3. INTRODUCTION

4. Battery Thermal Management Systems (BTMS) are designed to
regulate the temperature of batteries in electric vehicles (EVs),
hybrid electric vehicles (HEVs), and other applications. The
primary goal of a BTMS is to maintain the battery's optimal
operating temperature, typically between 20°C to 40°C (68°F to
104°F), to ensure.

5. IMPORTANCE
 Temperature-Dependent Chemistry: Battery performance and lifespan are highly dependent on
temperature.
 Heat Generation: Batteries generate heat during charging and discharging, which can lead to thermal
issues
 Environmental Factors: Ambient temperature, humidity, and solar radiation can impact battery
temperature.
Types of BTMS
 Thermoelectric Battery Management
 Air - Based Systems
 Phase Change Material (PCM)-Based Systems
 Liquid - Based Systyem

7. INTRODUCTION THERMOELECTRIC BTMS
 Thermoelectric Battery Management Systems (TE-BMS) are advanced systems
designed to regulate the temperature of batteries in electric vehicles,
renewable energy systems, and other applications. TE-BMS utilizes thermoelectric
technology to maintain optimal battery temperature, ensuring improved
performance, lifespan, and safety.
 Importance of Battery Thermal Management Battery temperature plays a
crucial role in determining its performance, lifespan, and safety. Extreme
temperatures can lead to:
 Reduced Performance: Decreased battery capacity and efficiency
 Degradation: Accelerated aging and reduced lifespan.
 Safety Risks: Increased risk of thermal runaway and fires

10. COMPONENTS

11. 1. Temperature sensors
(thermocouples, thermistors)
2. Cooling systems (heat sinks, fans,
liquid cooling)
3. Heating systems (resistive heating,
thermal electrical heaters)
4. Control unit (microcontroller,
FPGA)5. Power electronics (DC-
DC converters, switches)

12. FUNCTION

13. 1. Temperature Regulation: Maintains the battery temperature within a safe and optimal
range (usually between 20°C to 40°C) to ensure efficient performance, longevity,
and safety
2. Heat Dissipation: Removes excess heat generated by the battery during charging, discharging,
or idle periods, preventing overheating and potential thermal runaway.
3. Cooling: Provides active or passive cooling mechanisms, such as air cooling, liquid cooling
, or phase change materials, to reduce battery temperature.
4. Insulation: Helps to minimize heat transfer between the battery and the surrounding
environment, reducing heat loss or gain.
5. Protection: Prevents battery damage from extreme temperatures, which can affect performance,
lifespan, and safety.

14. CONSTRUCTION & WORKING

15. Construction of a BTMS
 Sensors: Temperature sensors (e.g., thermistors, thermocouples) monitor
the battery temperature.
 2. Heat Exchanger: A heat exchanger (e.g., radiator, heat sink) dissipates heat
from the battery.
 3. Cooling System: A cooling system (e.g., air cooling, liquid cooling) removes
heat from the heat exchanger.
 4. Control Unit: A control unit (e.g., microcontroller, PLC) monitors sensor
data and controls the cooling system
 5. Insulation: Insulation materials (e.g., foam, fiberglass) reduce heat transfer
between the battery and environment.

17. Working of a BTMS
 1. Temperature Monitoring: Sensors continuously monitor the battery
temperature.
 2. Temperature Comparison: The control unit compares the monitored
temperature to a setpoint temperature.
 3. Cooling Activation: If the battery temperature exceeds the setpoint, the control
unit activates the cooling system.
 4. Heat Dissipation: The heat exchanger dissipates heat from the battery to the
cooling system.
 5. Cooling: The cooling system removes heat from the heat exchanger, reducing the
battery temperature.
 6. Temperature Regulation: The control unit continuously monitors the battery
temperature and adjusts the cooling system to maintain the optimal temperature
range.

18. METHODOLOGY

19. A methodology for a battery thermal management system utilizing a
thermoelectric system typically involves: defining the battery system
requirements, selecting appropriate thermoelectric modules, designing the
thermal contact interface, integrating temperature sensors, implementing a
control algorithm to manage the thermoelectric cooling/heating, and finally,
conducting simulations and experimental validation to optimize the system
performance; key aspects include considering the battery cell arrangement,
heat generation profile, operating temperature range, and the power
consumption of the thermoelectric modules to achieve optimal thermal
management
