Battery Air Cooling System for LFP Battery Pack

The Challenge

Lithium Iron Phosphate (LFP) battery packs used in electric vehicles generate heat during charging and discharging due to internal resistance and electrochemical reactions. If this heat is not effectively dissipated, the battery temperature can exceed the safe operating range, leading to reduced battery efficiency, faster ageing, shorter lifespan, and potential safety risks. Manual temperature monitoring is impractical for large battery packs, making an automatic thermal management system essential to ensure reliable and safe battery operation.

Our Solution

To overcome this problem, an ESP32-based Battery Air Cooling System is developed for an LFP battery pack. The system uses 14 DS18B20 digital temperature sensors connected through two OneWire communication buses to continuously monitor the temperature at different locations within the battery pack. The ESP32 collects temperature data, identifies the highest temperature, and compares it with predefined threshold values. When the temperature exceeds the set limit (33°C), the ESP32 automatically activates the corresponding inlet fan and the common outlet fan through relay modules. The temperature readings, fan status, and system status are uploaded to Firebase Realtime Database and displayed on a real-time web dashboard for remote monitoring. This automatic air cooling system helps maintain the battery pack within a safe temperature range, improving battery performance, enhancing safety, and extending battery life.

A more robust, highly efficient thermal management solution is required to handle these extreme thermal loads.

Our Solution

We developed an advanced Liquid Cooling System designed to actively circulate coolant through strategically placed cold plates within the battery pack. This system provides superior heat dissipation compared to air cooling by maintaining uniform temperature distribution across all cells, even under heavy loads. Integrated thermal sensors and a smart controller continuously adjust the coolant flow rate based on real-time temperature data. This ensures the battery remains within its optimal operating window, maximizing charging efficiency, extending battery longevity, and ensuring the highest level of safety for high-performance EVs.

Digital Keyless Authentication System

Project Description

As electric vehicles become more common, ensuring vehicle security has become increasingly important. Most electric scooters rely on a physical key and basic ignition system, which can be vulnerable if the key is lost, duplicated, or misused. To address this issue, we developed a Smart Ignition System that adds an extra layer of security without making major modifications to the vehicle. Our project uses an ESP32 Development Board to implement a password-based authentication system. After turning the vehicle key ON, the rider must complete a secure authentication process before the vehicle can be unlocked. The ESP32 monitors the power button, detects a double press, and allows the user to enter a six-digit password using the vehicle's existing '+' and 'OK' buttons. Once the password is verified, relay modules simulate the required button presses to unlock the scooter and enable ignition. The system is designed to be compact, cost-effective, and easy to integrate with existing electric two-wheelers. By combining a traditional key with digital authentication, the project significantly improves vehicle security while maintaining a simple and user-friendly experience.

Problem Statement

Electric two-wheelers commonly use only a mechanical key or a basic electronic ignition system for vehicle access. If the key is stolen, duplicated, or accessed by an unauthorized person, the vehicle can be started easily, leading to security concerns and an increased risk of theft. There is a need for a secure, affordable, and intelligent ignition system that provides an additional authentication layer without affecting the vehicle's original electronics or user convenience.

Our Solution

To overcome these security challenges, we developed a Smart Ignition System using an ESP32 microcontroller. When the rider turns the key ON, the ESP32 powers up and waits for the user to press the power button. After detecting a double press, the system enters authentication mode. The rider enters a six-digit password using the existing '+' and 'OK' buttons available on the scooter. The ESP32 compares the entered password with the stored password. If the password is correct, the ESP32 activates relay modules that simulate the required button presses, allowing the scooter to unlock and start. If the password is incorrect, the relays remain inactive and the vehicle stays locked, preventing unauthorized access. This solution enhances security while requiring only minimal additional hardware, making it practical for both educational projects and real-world electric vehicle applications.
