The BMS system is the core component of electric vehicles and hybrid electric vehicles, and is also the heart of power. Mainly used for on-line detection and real-time monitoring of the car battery, providing vehicle battery voltage, current, temperature, SOC and insulation status and other information, while real-time determination of the battery's operating status and battery pack discreteness, if a fault occurs, The fault signal is sent to the vehicle in time and an alarm is issued. Its entire detailed function is as follows:
I. Failure prediction and alarm: In the course of operation of the battery pack, a single battery often appears damaged. If this condition is not found in time, it will cause other battery performance to be affected, and then cause the entire battery pack to be damaged. The battery management system can discover and notify maintenance personnel to repair or replace the battery in time to extend the life of the battery pack.
2. Dynamic balancing function: In the manufacturing process, the battery will inevitably appear inconsistent. In the running process, it directly shows that the battery voltage is inconsistent. As a result, the battery with small capacity is often in an overcharge state during the charging process, and the service life is shortened. An intelligent battery management system can balance battery imbalances and reduce battery damage caused by overcharging.
III. Prediction of the remaining capacity (SOC): In the case of strict requirements on the remaining capacity of the battery, the intelligent management system uses a high-precision, high sampling frequency measurement system to predict the SOC of the battery.
4. Remote monitoring interface: The system has rs-485/'target='_blank'>RS-485, CAN and other communication interfaces. It can use monitoring software to realize remote real-time monitoring. The software is simple to operate and displays clearly and clearly.
The following is a block diagram of the overall BMS program:
Whether in the process of signal monitoring, control, or external communication, the excellent features of our CF0505 products are the first choice for BMS product design. Our company passed the TS16949 certification in the quality management system, and this series of products meet the AEC-Q100 certification requirements in terms of materials, while the product operating temperature range is -50°C-125°C.
BMS power solution:
In response to the high reliability requirements of the automotive industry and the "heart" role of BMS in the vehicle system, Jin Shengyang has introduced the global automotive-grade DC_DC power supply module CF0505XT-1WR2 to fill the gap in the BMS power supply industry for the power supply industry.
