Power distributor unit designed for EV，known as “electric vehicle high voltage power distributor box” ,Electric vehicle power distribution box", "Electric vehicle power unit" and "Electric vehicle safety box", is an important part in EV.It supports function converting and power distribution to every systematic unit. Such as motor control unit, battery management system, charging system, heating system,etc. PDU can also provide short circuit protection, current leaking protection and IP protection.Battery lifespan is longer and maintenance cost of EV is reduced with this unit (Easy maintenance, convenient installation, space saving and reliable electric connection).
Features
Metal shell, flexible production, and low cost, good protective performance, light weight, good structural strength.
Master bus inside the box.
Designed with busbar solution make the product with low temperature rise, good heat dispassion,electric conductive better and installation easily.
Connector solution developed by busbar has been applied;meets in this products, it meet most customer request.
This product can be designed and manufactured and manufacture according to customer's requirements.
