Regenerative Braking System by ASLAM
This technical report summarizes the working of a regenerative braking system. It discusses how regenerative braking systems capture kinetic energy during deceleration and convert it back to electrical energy instead of wasting it as heat. The electrical energy is then stored in batteries and can be used to power electric motors, providing improved fuel efficiency compared to conventional braking systems. Regenerative braking is particularly beneficial in stop-and-go city traffic where it can provide most of the braking force needed. The report examines the components involved like motors, inverters, batteries and explains the working principle in detail.

Hybrid Electric Vehicle
A hybrid electric vehicle combines an electric motor with an internal combustion engine to improve fuel efficiency. There are two main types of hybrid configurations - parallel and series. In a parallel hybrid, both the engine and electric motor can power the wheels directly. In a series hybrid, the engine charges the battery which powers the electric motor to turn the wheels. Fuel cell hybrid vehicles use hydrogen to power an electric motor, providing emissions-free propulsion. Driving at a constant speed, avoiding abrupt stops, and driving more slowly can improve the fuel efficiency of any hybrid vehicle.

Hybrid electric vehicles
A hybrid electric vehicle combines an electric motor with an internal combustion engine or other power source to improve fuel efficiency. There are two main types of hybrid systems - series and parallel. In a series hybrid, the engine only charges a battery which powers the electric motor to turn the wheels. In a parallel hybrid, both the engine and motor can power the wheels directly and work together or independently based on driving conditions. Key components of hybrid systems include batteries to store energy, a generator to charge batteries, and regenerative braking to capture kinetic energy during deceleration. Hybrid vehicles provide benefits like lower emissions and fuel use while maintaining the performance of conventional vehicles.

Hybrid Electric vehicles
Hybrid electric vehicles (HEVs) combine a conventional internal combustion engine with an electric propulsion system. This allows HEVs to achieve better fuel economy than conventional vehicles. Modern HEVs make use of regenerative braking to capture kinetic energy and charge the battery. HEVs have both a mechanical drive train and an electric drive train consisting of a battery, electric motor, and power electronics. HEVs can reduce emissions and fuel consumption compared to conventional vehicles and other alternative fuel vehicles. However, HEVs currently have a higher purchase price though lower lifetime costs through fuel savings.

This document discusses hybrid electric vehicles (HEVs). HEVs combine an internal combustion engine with an electric motor to provide propulsion. They offer improved fuel efficiency over conventional vehicles through regenerative braking and a smaller engine size. HEVs are classified as parallel, series, or power-split based on how their electric and fuel-powered components are connected and work together. While more expensive initially, HEVs provide benefits like reduced emissions and fuel costs compared to traditional vehicles.
Electric cars is Our Feature
Electric cars are powered by electric motors and batteries instead of gasoline engines. They produce no tailpipe emissions, are quieter to drive, and have lower emissions than gas-powered cars. Some advantages of electric cars include being better for the environment if powered by renewable energy, requiring less maintenance than gas cars, and qualifying for tax credits. Key features of electric cars are powerful acceleration, regenerative braking that charges the battery, and roomy interiors since electric drivetrains take up less space than engines. Popular electric car brands in India include Tata, MG, Hyundai, and Mahindra, with prices usually higher than comparable gas-powered cars but lower operating costs.

HYBRID ELECTRIC VEHICLES
1. INTRODUCTION
A hybrid electric vehicle (HEV) has two types of energy storage units, electricity and fuel.
Electricity means that a battery (sometimes assisted by ultracaps) is used to store the energy, and that an electromotor (from now on called motor) will be used as traction motor.
Fuel means that a tank is required, and that an Internal Combustion Engine (ICE, from now on called engine) is used to generate mechanical power, or that a fuel cell will be used to convert fuel to electrical energy. In the latter case, traction will be performed by the electromotor only. In the first case, the vehicle will have both an engine and a motor.
Depending on the drive train structure (how motor and engine are connected), we can distinguish between parallel, series or combined HEVs.
Depending on the share of the electromotor to the traction power, we can distinguish between mild or micro hybrid (start-stop systems), power assist hybrid, full hybrid and plug-in hybrid.
Depending on the nature of the non-electric energy source, we can distinguish between combustion (ICE), fuel cell, hydraulic or pneumatic power, and human power. In the first case, the ICE is a spark ignition engines (gasoline) or compression ignition direct injection (diesel) engine. In the first two cases, the energy conversion unit may be powered by gasoline, methanol, compressed natural gas, hydrogen, or other alternative fuels.
Motors are the "work horses" of Hybrid Electric Vehicle drive systems. The electric traction motor drives the wheels of the vehicle. Unlike a traditional vehicle, where the engine must "ramp up" before full torque can be provided, an electric motor provides full torque at low speeds. The motor also has low noise and high efficiency. Other characteristics include excellent "off the line" acceleration, good drive control, good fault tolerance and flexibility in relation to voltage fluctuations.
The front-running motor technologies for HEV applications include PMSM (permanent magnet synchronous motor), BLDC (brushless DC motor), SRM (switched reluctance motor) and AC induction motor.
A main advantage of an electromotor is the possibility to function as generator. In all HEV systems, mechanical braking energy is regenerated.
The maximum operational braking torque is less than the maximum traction torque; there is always a mechanical braking system integrated in a car.
The battery pack in a HEV has a much higher voltage than the SIL automotive 12 Volts battery, in order to reduce the currents and the I2R losses.
Accessories such as power steering and air conditioning are powered by electric motors instead of being attached to the combustion engine. This allows efficiency gains as the accessories can run at a constant speed or can be switched off, regardless of how fast the combustion engine is running. Especially in long haul trucks, electrical power steering saves a lot of energy.

An electric vehicle (EV) is a vehicle that uses one or more electric motors for propulsion. It can be powered by a collector system, with electricity from extravehicular sources, or it can be powered autonomously by a battery (sometimes charged by solar panels, or by converting fuel to electricity using fuel cells or a generator). EVs include, but are not limited to, road and rail vehicles, surface and underwater vessels, electric aircraft and electric spacecraft. For road vehicles, together with other emerging automotive technologies such as autonomous driving, connected vehicles and shared mobility, EVs form a future mobility vision called Connected, Autonomous, Shared and Electric (CASE) Mobility.

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.

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.
DEEP LEARNING FOR SMART GRID INTRUSION DETECTION: A HYBRID CNN-LSTM-BASED MODEL
As digital technology becomes more deeply embedded in power systems, protecting the communication
networks of Smart Grids (SG) has emerged as a critical concern. Distributed Network Protocol 3 (DNP3)
represents a multi-tiered application layer protocol extensively utilized in Supervisory Control and Data
Acquisition (SCADA)-based smart grids to facilitate real-time data gathering and control functionalities.
Robust Intrusion Detection Systems (IDS) are necessary for early threat detection and mitigation because
of the interconnection of these networks, which makes them vulnerable to a variety of cyberattacks. To
solve this issue, this paper develops a hybrid Deep Learning (DL) model specifically designed for intrusion
detection in smart grids. The proposed approach is a combination of the Convolutional Neural Network
(CNN) and the Long-Short-Term Memory algorithms (LSTM). We employed a recent intrusion detection
dataset (DNP3), which focuses on unauthorized commands and Denial of Service (DoS) cyberattacks, to
train and test our model. The results of our experiments show that our CNN-LSTM method is much better
at finding smart grid intrusions than other deep learning algorithms used for classification. In addition,
our proposed approach improves accuracy, precision, recall, and F1 score, achieving a high detection
accuracy rate of 99.50%.
