Fuel cells
Fuel cells generate electricity through an electrochemical reaction of hydrogen and oxygen. They are composed of an anode, cathode, and electrolyte membrane. Two main types are polymer electrolyte membrane fuel cells, which operate at lower temperatures and pressures, and alkaline fuel cells, which use an aqueous alkaline electrolyte. Fuel cells have benefits like low emissions, high efficiency, reliability, and fuel flexibility.
concept of electric car
An electric car runs on a battery-powered electric motor rather than a gasoline engine. It has three main parts: a battery, motor, and controller. When the accelerator is pressed, the controller directs electricity from the battery to power the motor, which transforms the energy into mechanical motion to turn the wheels. Electric cars provide environmental benefits over gas vehicles as they produce no direct emissions and can use recyclable batteries.
Regenerative braking system
This document provides an overview of regenerative braking systems. It discusses:
- The history of regenerative braking, which was first patented in 1908 and later commercialized by Toyota and other automakers for hybrid vehicles.
- The principles of regenerative braking, which involve using the electric motor as a generator to convert kinetic energy during braking into electrical energy that can be stored in batteries.
- The components and working of regenerative braking systems in hybrid and electric vehicles, which feed generated electricity back into the battery charging system.
- The benefits of regenerative braking, which include improved fuel economy and reduced emissions.
Electric Monowheel BMS Simulation PPT by Ayush Dubey
This document summarizes an electric monowheel battery management system (BMS) simulation project. The project aims to design a small, portable, low-cost electric vehicle for transportation using lithium-ion batteries. It discusses electric vehicles, a monowheel design, BMS components and functions, and implementing a BMS simulation in Matlab/Simulink. Key blocks used include Goto/From for signal passing, Powergui for circuit solving, and Scope for output display.
Regenerative Braking of BLDC Motors
This document discusses regenerative braking of BLDC motors. It describes how kinetic energy from a motor during braking can be stored in a battery through regenerative braking. It then provides simulations and test results of using a 3-phase MOSFET bridge rectifier with a boost converter to regeneratively brake a BLDC hub motor on an e-bike. The maximum efficiency was 55% at 50% duty cycle, but maximum braking force occurred at 70% duty cycle. A PID controller is proposed to maintain a constant braking force at varying motor speeds.
Kinetic Energy Recovery Systems
These slides use concepts from my (Jeff Funk) course entitled analyzing hi-tech opportunities to analyze how the economic feasibility of kinetic energy recovery systems is slowly becoming better through improvements in batteries, hydraulic pumps, and flywheels. Many of these systems are currently used in Formula 1 race cars because they enable these cars to achieve higher acceleration and longer times between pit stops. For consumers, flywheels may become the energy storage technology of choice for vehicles particularly as improvements in carbon nanotubes and graphene occur.
The rates of improvement for energy and power storage densities for batteries have been very slow and those of flywheels have been much faster. One of the reasons for the rapid improvements in the densities for flywheels is that improvements in the strength per weight of materials have enabled faster rotations and the storage densities are a function of rotation velocities squared. As shown in the slides, carbon fiber has about four times the strength to weight ratio and seven times the energy density of glass. Since carbon nanotubes have strength to weight ratios 15 times higher and graphene has ones 30 times higher than do carbon fiber, energy storage densities of 120,000 kJ/kg or 33.6 kWh are possible with graphene. This energy density is about 100 times higher than is currently available from lithium-ion batteries.

Regenerative braking system
This document provides an overview of regenerative braking systems. It begins with an introduction and history section describing early patents and developments. The principles and components of regenerative braking are then explained, noting that kinetic energy is converted to electrical energy during braking via electric motors or hydraulic pumps. Applications in electric vehicles, hybrids, and locomotives are discussed. The benefits include improved efficiency and emissions reductions, while costs and complexity are disadvantages. Regenerative braking effectively improves vehicle performance by recapturing kinetic energy.
Braking system
This document discusses regenerative braking systems. It explains that conventional braking systems waste kinetic energy as heat, while regenerative braking systems capture this energy and convert it to electrical energy which is stored in batteries. There are different types of energy storage used. Regenerative braking can recapture around half of the energy lost in braking, improving fuel efficiency by 25-45%. While it has limitations, regenerative braking provides benefits by reducing wear on brake pads and fuel usage, making hybrid and electric vehicles more efficient. Popular car models that use this technology are listed.
Regenerative braking
A regenerative brake uses a generator, battery, and rectifier to convert a vehicle's kinetic energy into electrical energy during braking. The generator produces 3-phase AC power that is converted to DC by the rectifier and stored in a battery. This stored energy can then be used to power the vehicle or fed back into the electrical supply system. The system includes a 3-phase generator, battery, transformer, rectifier, and variable resistor. When braking occurs, the generator converts mechanical braking force into 3-phase AC which is converted to DC by the rectifier and stored in the battery.
Regenerative braking Project report
This project report describes the development of a regenerative braking system for bicycles that captures kinetic energy lost during braking and uses it to power LED safety flashers. The system was designed for urban commuter cyclists. It includes custom direct-pull brake calipers with friction pads and an integrated DC motor generator. Testing showed that the system can power LED flashers continuously when braking occurs 8 or more times per mile, and semi-continuously when braking occurs 4 times per mile, which would be sufficient for most urban commutes. The regenerative braking system provides safety benefits to cyclists without requiring additional physical exertion compared to existing human-powered lighting systems.
Regenerative braking
This document discusses regenerative braking in electric vehicles. It begins by introducing regenerative braking and its importance for electric vehicles in conserving electrical energy. It then provides details on the components and design of a regenerative braking system, including using an induction motor, alternator, rectifier, battery, transformer and load. The document describes the block diagram and working of the system, where kinetic energy recovered during braking is used to charge the battery and power a light bulb load.
iaetsd Use of photo voltaic panels to increase the car’s mileage
The document proposes using photovoltaic (solar) panels to power the electrical components of a car in order to reduce fuel consumption and increase mileage. The main electrical loads such as the air conditioner compressor, headlights, music system, and horns would be powered by the solar panels. This is estimated to increase mileage by 2-3 kilometers per liter of fuel. Over the average 15-year lifespan of a car, total fuel savings could range from Rs. 70,500 to Rs. 2,35,000 for diesel cars and Rs. 90,000 to Rs. 2,57,000 for petrol cars. The system would use solar panels, a charge controller, batteries, and a permanent magnet DC motor to drive
Electric car
This document discusses the components and history of electric vehicles. It begins with an introduction stating that electric cars are propelled by electric motors powered by rechargeable batteries.

IRJET- Design and Implementation of Electric Vehicle
This document describes the design and implementation of an electric vehicle. It discusses the various components of an EV including the motor, motor controller, battery, braking system, and chassis design. The key points are:
1. An electric vehicle uses a battery and electric motor instead of an internal combustion engine. This makes the EV more efficient and reduces emissions compared to gas-powered vehicles.
2. The main components discussed are the brushless DC hub motor, motor controller, lithium-ion battery, disc brakes, and a lightweight chassis.
3. Lithium-ion batteries are well-suited for electric vehicles due to their high energy density and power, low self-discharge, and
Regenerative braking system
A regenerative brake system converts the kinetic energy of a moving vehicle into other forms of energy through different mechanisms. There are three main types: electric energy storage which uses a motor-generator and batteries; compressed gas storage which uses a flywheel; and hydraulic storage which uses a pump and accumulator tank. These systems can capture 50-70% of the energy lost during braking to improve efficiency. The optimal system captures energy hydraulically and uses it to power an electric motor for hybrid or electric vehicles.

It concludes that KERS can improve vehicle performance and efficiency.
Regenerative Braking System ppt
This document discusses regenerative braking systems. It begins by explaining conventional braking systems, noting that they waste up to 30% of a car's energy through heat dissipation.

Power generating using Regenerative Braking system ppt
Regenerative braking is a system used in hybrid vehicles to capture kinetic energy during braking that would otherwise be lost as heat. The system uses the electric motor to act as a generator during braking, converting the energy into electricity that is stored in the vehicle's batteries. This captured energy can then be used to help power the electric motor, improving the vehicle's efficiency. Regenerative braking provides benefits like greater fuel economy and emission reductions compared to traditional braking systems that waste energy as heat. While more efficient, regenerative braking systems still lose some energy through heat and resistance in transferring and storing the captured kinetic energy in the batteries.

The document presents the history of regenerative braking and provides examples of vehicles that use this technology today, concluding that regenerative braking improves fuel efficiency and reduces emissions.

A kinetic energy recovery system (often known simply as KERS, or kers) is an automotive system for recovering a moving vehicle's kinetic energy under braking. The recovered energy is stored in a reservoir (for example a flywheel or high voltage batteries) for later use under acceleration
Fabrication of Prototype Model of Infrared Sensor Based Regenerative Braking...
The objective of this paper is to stored the kinetic energy dissipated in the brakes to accelerate
the vehicle. This project is based on prototype model of Regenerative braking system using electromagnetic
clutch. Regenerative braking results in an increase in energy output for a given energy input to a vehicle,
the efficiency is improved. The amount of work done by the engine of the vehicle is reduced, in turn
reducing the amount of prime energy required to propel the vehicle. In order for a regenerative braking
system to be cost effective the prime energy saved over a specified lifetime must offset the initial cost, size
and weight penalties of the system. The energy storage unit must be compact, durable and capable of
handling high power levels efficiently. The energy can be directly provided to dynamo itself to generate
current and will be displayed on the Ammeter installed in the set up. This set up also consists of an Infrared
Sensor which helps to prevent the frequency of accidents increasing due to inefficient braking system and
therefore can be considerably avoided using IR sensors. The vehicle instantly stops as any object appears
in front of it where IR Sensors are installed.
Presentation1
This document describes the design of a self-charging electric bicycle. It consists of a bicycle, battery, DC brushless motor, alternator, gear mechanism, and other components. The alternator generates power from pedaling that is stored in the battery. The motor uses power from the battery to drive the rear wheel. A gear system connects the pedaling to the alternator and motor. The system allows the bicycle to be powered by either pedaling or the motor using stored energy from the alternator.
Architecture of electric vehicles.pptx
The architecture of electric vehicles (EVs) encompasses the intricate integration of components that enable their electric propulsion. This includes the arrangement of the electric motor, power electronics, and energy storage system (usually lithium-ion batteries) within the vehicle's frame. The architecture also involves control systems, thermal management, and regenerative braking mechanisms to optimize efficiency. This thoughtfully designed structure contributes to EVs' environmental benefits and provides a foundation for continuous innovation in the realm of sustainable transportation.

and weight penalties of the system. The energy storage unit must be compact, durable and capable of
handling high power levels efficiently. The energy can be directly provided to dynamo itself to generate
current and will be displayed on the Ammeter installed in the set up. This set up also consists of an Infrared
Sensor which helps to prevent the frequency of accidents increasing due to inefficient braking system and
therefore can be considerably avoided using IR sensors. The vehicle instantly stops as any object appears
in front of it where IR Sensors are installed.

Basic of electrical vehicles components and parts
This document discusses electric vehicles and their components. It describes how electric vehicles work and their advantages over gas-powered vehicles, such as being cheaper to run and causing less pollution. The main components of an electric vehicle are described as the traction battery pack, power inverter, controller, electric traction motor, charger, and transmission. Several types of electric vehicles are also outlined, including battery electric vehicles (BEVs), hybrid electric vehicles (HEVs), plug-in hybrid electric vehicles (PHEVs), and fuel cell electric vehicles (FCEVs). The roles and working principles of mechanical engineers in electric vehicle design and testing are summarized.
Electric vehicles
Electric vehicles use lithium-ion batteries to power electric motors. There are two main types of electric motors used - DC motors which are directly powered by current, and AC motors which use an inverter to convert current to alternating current to power the motor. Hybrid electric vehicles can combine electric motors with combustion engines or renewable energy sources to improve efficiency. Regenerative braking also makes electric vehicles more efficient by recharging the battery with kinetic energy during braking. Electric motors provide torque more efficiently than combustion engines, allowing for quicker acceleration. Electric vehicles also have fewer moving parts and require less maintenance than gasoline vehicles.
ELECTRIC VEHICLES
Electric vehicles use lithium-ion battery packs to power electric motors instead of internal combustion engines. The batteries provide electricity to the motor which turns the wheels and propels the vehicle forward. When the accelerator pedal is pressed, the controller regulates energy from the batteries to send power to the motor based on how far the pedal is pressed, causing the motor to rotate and move the car. Key components include the battery, motor, controller, and onboard charger which converts AC power to DC for charging the batteries.
How does Electric Vehicles Work_esbeem_Learn Engineering
The document discusses the key components and workings of an electric car. It explains that electric cars use induction motors powered by lithium-ion battery packs.

The aquaponic system of planting is a method that does not require soil usage. It is a method that only needs water, fish, lava rocks (a substitute for soil), and plants. Aquaponic systems are sustainable and environmentally friendly. Its use not only helps to plant in small spaces but also helps reduce artificial chemical use and minimizes excess water use, as aquaponics consumes 90% less water than soil-based gardening. The study applied a descriptive and experimental design to assess and compare conventional and reconstructed aquaponic methods for reproducing tomatoes. The researchers created an observation checklist to determine the significant factors of the study. The study aims to determine the significant difference between traditional aquaponics and reconstructed aquaponics systems propagating tomatoes in terms of height, weight, girth, and number of fruits. The reconstructed aquaponics system’s higher growth yield results in a much more nourished crop than the traditional aquaponics system. It is superior in its number of fruits, height, weight, and girth measurement. Moreover, the reconstructed aquaponics system is proven to eliminate all the hindrances present in the traditional aquaponics system, which are overcrowding of fish, algae growth, pest problems, contaminated water, and dead fish.

Embedded machine learning-based road conditions and driving behavior monitoring
Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.

This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.

The proper function of the integrated circuit (IC) in an inhibiting electromagnetic environment has always been a serious concern throughout the decades of revolution in the world of electronics, from disjunct devices to today’s integrated circuit technology, where billions of transistors are combined on a single chip. The automotive industry and smart vehicles in particular, are confronting design issues such as being prone to electromagnetic interference (EMI). Electronic control devices calculate incorrect outputs because of EMI and sensors give misleading values which can prove fatal in case of automotives. In this paper, the authors have non exhaustively tried to review research work concerned with the investigation of EMI in ICs and prediction of this EMI using various modelling methodologies and measurement setups.
