The battery management system is an essential part of the new energy vehicle, which is integrated with the battery and management system and represents the three main technologies of the new energy vehicle. 

With the promotion of new energy cars and more companies are realizing the functionality of battery management systems, which offers great business opportunities. However, there were many challenges in developing the system. Challenges are obstacles that must be overcome in the further development of new energy cars.


Three different aspects demonstrate the importance of a battery management system for new energy cars. First, the system can obtain traction battery parameters to ensure the safe operation of the battery and the entire vehicle. Second, the parameters provided by this system help the control system to develop a proper management strategy that has a positive impact on the dynamics, safety, and low energy consumption of electric vehicles.

Battery performance such as stability, safety, and lifetime is affected by temperature. By controlling the temperature of the battery, the battery is kept under ideal temperature conditions. You must keep the temperature at each corner of the battery case to prevent damage to the device. Identity is another focus of the battery.

The capacity and internal resistance of a battery differ for different batches due to different containers and materials. The effectiveness will vary greatly after use. Other causes can also lead to incompatibility, eg. Self-discharge, and distribution of voltage and current.
