High-voltage distribution box for power battery

The invention relates to a high-voltage distribution box for a power battery. High-voltage devices in the high-voltage distribution box for the power battery are individually partitioned by plastic insulation partitions, in doing so, mutual interference is reduced, insulation distance is increased, and short circuit risk caused by direct contact of conductive parts among the high-voltage devices is avoided. Meanwhile, the high-voltage devices are electronically connected through copper bars, so that high-voltage electrical connection of the high-voltage distribution box is compact, and system integration and spatial utilization rate is increased. By the distribution box, current distribution control can be provided for a motor controller and electric accessories of a hybrid electric vehicle, stable current detecting terminals, electric leakage detecting terminals and low-voltage signal control terminals can be provided for a battery management system, and reverse overcurrent protection can be provided for a power battery of an electric vehicle. Accordingly, safety of a power supply system of the electric vehicle is greatly improved.
