🛡️ 3. Safety & Protection Mechanisms

⚠️

Smart Thermal Management

Linear derating above 85°C MOSFET temp; complete cut-off shutdown over 100°C.

⚠️

Hardware-Level Overcurrent / Short-Circuit

High-frequency closed-loop response (<10ms) with microsecond gate-level cut-off.

⚠️

Over/Under-Voltage Lockout

Prevents battery over-discharge/charge; includes regenerative braking overvoltage protection.

⚠️

Signal Loss Protection (Failsafe)

Automatic safe deceleration and braking within 100ms of control/CAN signal loss.
