AI Technical Summary
Existing electric vehicle systems suffer from significant stray magnetic field losses, battery overheating, and thermal runaway risks. Current technologies cannot achieve coordinated optimization of active intervention and range improvement, and have insufficient safety redundancy and high energy consumption.
The system employs AI to perceive the status of the three electrical components (battery, motor, and electronic control system) in real time and dynamically adjust the magnetic field. Combined with three layers of composite protective materials, the system utilizes a three-electric status perception unit, an AI active magnetic control core unit, an active magnetic control execution module, and a vehicle safety collaborative control unit to achieve dynamic adjustment of the magnetic field and safety strategies.
It reduces eddy current losses by 8% to 18%, lowers battery temperature by 3°C to 7°C, increases range by 5% to 12%, delays thermal runaway by 15 to 35 minutes under extreme conditions, and can be pre-installed or retrofitted without altering the original vehicle structure, keeping costs under control.
