EV Battery CAN Protocol Hacker bei Allye Energy

Allye Energy is revolutionising the energy storage sector with our cutting-edge Battery Energy Storage Systems (BESS) built using repurposed EV batteries. As part of our innovative approach to sustainable energy solutions, we are expanding our capabilities to integrate DC fast charging technology with our battery energy storage systems, creating a comprehensive energy ecosystem for the future of clean mobility and energy storage.

We need a 'hacker' - someone with the rare combination of automotive cybersecurity skills, embedded systems expertise, and the tenacity to reverse engineer complex CAN protocols. You'll be breaking our dependence on black-box third-party controllers by developing our own in-house solutions that work across multiple EV platforms from leading manufacturers.
 

Responsibilities

Reverse Engineering & Protocol Analysis

• Reverse engineer CAN bus protocols for leading EV manufacturer battery platforms
• Decode and create DBC files from scratch through systematic CAN logging and signal analysis
• Develop control code to mimic vehicle CAN messages to satisfy battery BMS requirements

Controller Development

• Design and implement multi-platform battery controllers using ESP32/STM32 microcontrollers
• Create embedded C/C++ firmware for automotive-grade CAN communication
• Develop Python-based analysis tools for automated CAN protocol discovery
• Build hardware prototypes integrating CAN transceivers, safety systems, and monitoring interfaces

Cross-Platform Integration

• Establish communication protocols that work seamlessly across Tesla and other major EV battery architectures
• Handle complex multi-bus scenarios (PCAN, BCAN, diagnostic CAN) found in modern EVs
• Implement safety-critical messaging for battery thermal management, balancing, and protection systems
• Create unified software architectures that abstract OEM-specific differences

Testing & Validation

• Develop comprehensive test suites for battery controller validation across all target platforms
• Perform real-world testing with actual EV battery packs in controlled environments
• Create automated testing frameworks using CANoe, SavvyCAN, or custom tooling
• Document reverse engineering methodologies for knowledge transfer and future platform additions
