Battery car equipment: exploration of efficient wiring harness solutions

Sale leads: There are many types of energy storage, among which electrochemical energy storage is a relatively key energy storage method. The electrochemical energy storage system is mainly composed of energy storage batteries, inverters, BMS battery management systems and other electrical equipment. The energy storage BMS system is responsible for communicating with the power grid, controlling key parameters such as harmonics and frequency, and realizing information interaction between the PCS and the monitoring system. Then the PCS controller obtains the status information of the battery pack through the CAN interface and the BMS communication, is responsible for monitoring the working status of each single battery, and uploads battery-related information and status through communication to prevent the battery from overcharging and over-discharging, which plays an effective protective role.

The energy storage monitoring system is responsible for the interface between the BMS battery management system and the distribution network system, and can accept dispatching instructions, which helps to complete the actual application of the power grid such as battery charging and discharging control, support for independent off-grid systems, peak shaving and valley filling, and smooth output of new energy power generation. BMS plays a vital role in the entire electrochemical energy storage system.

There are a large number of battery clusters in the energy storage system, and the battery clusters have balanced management and circulation management. The energy storage system BMS has high requirements for anti-interference. The energy storage BMS system is mainly used for the management and control of energy storage batteries, mainly including BAU master control management unit, BCU master control management unit, and BMU slave control management unit. The energy storage BMS system is conducive to extending the service life of the battery, enhancing the stability and balance of the battery, reducing the operation and maintenance costs of the system, and improving the system efficiency. In order to improve the reliability and anti-interference of the energy storage system, the energy storage harness connection is required.
