Information

BMS,made up of colorful touch screen ,master BMS ,voltage ,temperature collection module and external charge control module,is mainly designed to monitor and report charge and discharge process during start-up and manage the exterior charge.. Collection module, is mainly used to collect voltages of all individual cells and temperatures in the battery pack, monitor the critical state of battery and send information to master BMS. The master BMS mainly collects state information of every cell and send the information to the vehicle management system ,in the meantime display the voltage, current, temperature and total capacity in the colorful touch screen.

1. The master BMS is made up of a colorful touch screen and a managing computer. On the homepage of the screen, you can find the pack total voltage, pack total current ,SoC, maximum temperature, charge and discharge states and voltage of individual cells in each pack displayed in turn. Especially, you can see the state of each cell through the matrix display of cell state.
2. Through CAN main cable, BMS sends message of battery’s state including each pack’s temperature, capacity and ability to charge and discharge to the vehicle management system for its reaction.
3. The system collection board of voltage and temperature adopts module structure and each module manages 12 cells and a multipath temperature sensor. The collection board can be installed separately with battery cases connected through message cable in case that EV batteries are installed in a scattered way.
4. The number of batteries managed by collection board of voltage and temperature can be flexibly set from 6 to N(N≤13) ,wired with N+1.
5. Master BMS have the CAN main cable interface which is compatible with ISO 11898. 
6. Master BMS provides the alarm interface for upper and lower alarm, temperature upper alarm and over charge alarm.
