The Heat Dissipation Unit HDU is an essential safety and performance component within the Movaria Powertrain, engineered to manage excess electrical energy and maintain system stability. During regenerative braking or energy recuperation — especially when the battery is fully charged, thermally stressed, or cell-unbalanced — the HDU safely diverts surplus energy by converting it into heat. This process mitigates voltage spikes and prevents potential damage to the battery management system (BMS) and power electronics. Key features include:

• Active thermal regulation via continuous temperature monitoring.

• Fail-safe energy dissipation to protect against overvoltage conditions.

• System-wide protection, ensuring the longevity of components and the safety of the user.

The HDU operates autonomously and in real - time, forming a critical layer of protection in high - performance and high - recovery scenarios.
