                              BATTERY COOLING SYSTEM FOR ELECTRIC VEHICLES

Leena Ajay Bhoi. SY-B, (Electrical)

bhoileena18@gmail.com

Abstract

The safety of lithium-ion batteries in vehicles is a priority for the automotive industry. The focus of the development activities is the reduction of risks and the improvement of the safety concepts and systems. Constant monitoring of battery parameters such as temperature, gas level, and voltage, current will alert the system to any abnormal or worse condition of emergency. As these conditions may lead to battery fire or battery explosion, early indication of such activities becomes very important. In a practical case fire or any accidental impact on the battery may cause an internal short circuit of the battery, which leads to excessive overheating of the battery, which leads to an explosion and fire. Our smart sensor-based network will keep batteries continuously monitoring, and in case of emergency, quickly battery will be taken out automatically through the stepper-based locks. This system will be extremely beneficial for saving the valuable life of the driver and the valuable investment in the vehicle.

1. Introduction:

An electric vehicle battery (EVB), also known as a traction battery, powers the electric motors of battery electric vehicles (BEVs) and hybrid electric vehicles (HEVs). These rechargeable batteries, typically lithium-ion, are designed for high capacity, with a focus on power-to-weight ratio, specific energy, and energy density to improve vehicle performance. Unlike starting, lighting, and ignition (SLI) batteries, EVBs are deep-cycle batteries intended to provide power over long durations. While current battery technologies have lower specific energy compared to liquid fuels, they continue to evolve, driven by advances in portable electronics. Lithium-ion and lithium polymer batteries are most common due to their high energy density. Battery packs are a significant cost in EVs, but their prices have decreased by 87% since 2010, making long-range electric vehicles like the Tesla Model S commercially available. EVs are also much more energy-efficient than vehicles with internal combustion engines, reducing operating costs.

 2. Problem Identification

The primary problem with electric vehicle (EV) batteries lies in their relatively low specific energy and energy density compared to liquid fuels, which limits the maximum all-electric range of EVs. While lithium-ion batteries, the most common type in modern EVs, offer high energy density and improved performance due to advancements in technology, their high cost remains a significant challenge, as the battery pack constitutes a major portion of the vehicle’s total cost. Additionally, the weight and size of batteries need to be minimized to enhance vehicle performance, posing a technical constraint. Despite their efficiency and reduced operating costs compared to internal combustion engines, further innovation is needed to address these limitations and make EVs more accessible and practical for widespread use.

3. System Overview

The Battery Cooling System for Electric Vehicle diagram is shown in Fig. 1.

Fig 1. Circuit diagram of the Battery cooling system for an Electric Vehicle

1. Gas Sensor (MQ-8): Detects the presence of flammable gas in the environment and outputs an analog signal proportional to the gas concentration.

2. Arduino Nano: The microcontroller processes the sensor data. Based on the threshold set in the program, it activates corresponding components (e.g., buzzer, relays).

3. SIM Module (SIM1): Sends alert messages (SMS) or calls when a gas leak is detected.

4. Buzzer (BUZ1): Provides an audible alarm when a gas leak is detected.

5. Relays (RL1, RL2): Controlled by the Arduino via transistors (Q1 and Q2). They can switch on/off external appliances or safety devices (e.g., exhaust fans).

6. Diodes (D2, D3): Protect the transistors and relays from back-EMF generated when the relays are switched off.

7. LCD Display (LCD1): Displays the system status, such as gas concentration or warnings.

8. Temperature Sensor (MAX6675 + Thermocouple TC1): Monitors the ambient temperature and provides data to the Arduino for additional safety monitoring.

9. Power Supply: Batteries (BAT1 and BAT2) provide power to the system, regulated and protected using diodes (e.g., D1).

 This system can detect gas leaks, alert users via SMS/calls, sound an alarm, and control safety devices automatically.

4. The need fora battery cooling system for electric vehicles

The need for electric vehicle batteries (EVBs) arises from the growing demand for sustainable and energy-efficient transportation solutions to reduce reliance on fossil fuels and decrease greenhouse gas emissions. These batteries must offer high energy density, specific energy, and power-to-weight ratios to maximize vehicle range, performance, and efficiency while minimizing weight and cost. Advances in rechargeable battery technologies, particularly lithium-ion, are critical to meeting these needs by improving energy storage capacity, reducing costs, and enabling frequent charging and discharging cycles without compromising performance. This is essential for the widespread adoption of battery electric vehicles (BEVs) and hybrid electric vehicles (HEVs) across various segments of the automotive market.

5. Result

The Battery cooling system for electric vehicles hardware circuit is shown in Fig. 2.

Fig 2. Project photo of the Battery cooling system for electric vehicles

Electric vehicle batteries (EVBs), typically lithium-ion, power electric and hybrid vehicles by providing sustained energy. They are designed for high capacity, lightweight, and efficient performance, although their energy density is lower than liquid fuels, limiting electric range. Advances in battery technology, driven by demands in portable electronics, have improved their performance and cost. As of 2019, the cost of EV batteries dropped significantly, making BEVs more affordable. Despite lower operating costs, battery packs remain a significant expense in EVs. Energy density, or energy per unit volume or mass, is key to improving vehicle range and efficiency.

6. Conclusion

Advanced battery cooling systems are crucial to the evolution of electric vehicle (EV) technology, enhancing performance, longevity, and sustainability. By effectively regulating battery temperatures, these systems improve energy efficiency, extend driving range, and reduce range anxiety, thus supporting EV adoption and global sustainability goals. They preserve battery health, minimize degradation, and reduce waste, increasing economic and environmental viability. Innovations in cooling technologies, including smart and adaptive systems powered by data analytics and machine learning, optimize energy usage and battery lifespan. This holistic approach ensures scalable, cost-effective, and environmentally friendly solutions, driving cleaner transportation and climate change mitigation efforts.

7. Future Scope

1. A more reliable and safety-ensuring system for safety while using electric vehicles.
2. Automatic and trouble-free operation, which should not disturb the normal operation of the vehicle.
3. Smart safety systems should not get damaged, and its internal faults should be minimal.
4. The future scope for a project on a battery cooling system for electric vehicles includes enhancing cooling efficiency through advanced materials and designs, integrating smart sensors for real-time monitoring and optimization, and developing innovative thermal management strategies to extend battery lifespan and enhance overall vehicle performance.
5. Additionally, exploring sustainable and eco-friendly cooling solutions to minimize environmental impact will be crucial.
