System Brief
GTBMS005A-MC16 battery management system consists of a colourful led screen with touch panel, a GTBMS005A-MC11 host controller, a GTBMS005A-VT voltage、temperature sampling modules and current sampling module, detecting all cells` voltage of the battery pack, total current of the pack and the surrounding temperature. Detailed performances as follow:
A. The host master consists of a colorful screen and managing calculator, the screen displays total voltage and current of the pack、storage electrical quantity(SOC)、 maximal temperature , you can examine all the sampled data that includes each cell`s voltage、temperature、capacity、energy and so on through the screen; You can set the system running parameters through the screen, the running parameters includes the choice whose number of batteries that sampling modules manage、cell`s voltage upper/lower limit alarm、temperature upper limit alarm、the highest charging 、current upper limit alarm、the biggest voltage differences 、charging cycle times、battery health index、SOC initialization、 rated capacity、storage electrical quantity calibration coefficient and so on.
B. System voltage and the temperature collect board adopt modularization structure; Every module manages 10 battery and 1 road temperature. The battery collecting board but adapting to an electric motor car distributes broader characteristic, follow the battery box to disperse installation, between require mains lead and a little data communication to link up only.
C. The amount of voltage ane temperature sampling boards management battery can be set from 1~N(N≤10)flexible, connecting method adopts N+1; Temperature can be set to have or have no depends on need.
D. Current sampling board provides a loop current sampling data,hall sensor is used as current sensor.
E. The host provides CAN Bus (cable) which is compatible with ISO 11898 standard completely.
F. The host provides USB interface that can be connected with computer. It can save all data within 7days and receive all data through the BMS application software.
G. The host provides alarming interface,coltage upper/lower limit,temperature upper limit alarm,over current alarm,etc.
