Designing Intelligent Battery Junction Boxes for Advanced EV Battery Management Systems
As electric vehicles become more popular, the challenge for automakers is to reflect true range while making vehicles more affordable. This means making the battery packs lower cost with higher energy densities. Every single watt-hour stored and retrieved from the cells is critical to extending the driving range.
The purpose of power distribution in automobile power management is explained in this introduction, along with the difficulties that contemporary power distribution systems face. Role of Power Distribution in Automotive Power Management. One way to think of power distribution is as the electrical components of a vehicle''s circulatory system.

Battery Management Systems for Electric Vehicles | SRMTech
It is challenging to monitor battery pack performance since each cell in each module tends to charge and discharge at different rates. Also, each cell functions differently due to temperature, health status, and energy. Therefore, each battery cell must be independently observed for safer and more efficient operation.
For example, the unit supports function conversion and power distribution to each system unit. Such as engine control unit, battery management system, charging system, heating system, etc. The PDU can also provide short-circuit protection, leakage current protection and IP protection. ... to battery pack: MSD: 350~500A: Motor interface: 240A ...
