Development status of battery management system
Aug 08, 2018

In the future, electric vehicles will use lithium batteries as the main driving source. The main reason is that lithium batteries have high energy density advantages, so the performance is relatively stable. However, the quality of the lithium battery is difficult to master when it is mass-produced. There is a slight difference in the power of the battery core when it leaves the factory. With the operating environment, aging and other factors, the inconsistency between the batteries will become more and more obvious, and the battery efficiency and life will also be worse. In addition, if it is overcharged or over-discharged, it may cause safety problems such as fire and burning. Therefore, the battery management system (BMS) can accurately measure the battery pack usage, protect the battery from overcharging and discharging, balance the power of each battery in the battery pack, and analyze and calculate the battery pack's power and convert it into driving. Understand the endurance information to ensure that the power battery can operate safely.

In 2012, the global battery management system (BMS) market value increased by more than 10%, and the growth rate will jump to 25-35% from 2013 to 2015. At this stage, whether it is an OEM, a battery factory, or a related vehicle-electric component factory, it has invested in battery management system (BMS) research and development in order to grasp the key technologies of the electric vehicle industry. Since the vehicle factory is a user of the battery management system, the car factory has many It prefers to use its own software processing and is controlled by a special factory to maintain operational flexibility. The development of the battery management system (BMS) industry may be similar to lithium batteries. In order to master key technologies, the car manufacturers will cooperate closely with long-term suppliers to develop products, which is difficult for newcomers to enter. Therefore, in the future, newcomers want to cut into the supply chain of the car manufacturer. In addition to strengthening the cooperation relationship with the relevant supply chain, it is only possible to seize the opportunity to build a customized solution for the demand.
