System brief
GTBMS005 battery management is made up of a GTBMS005A-MC8 management host、 two GTBMS005A-VCT voltage/current/temperature module, can measuring all voltage of single batteries, total current of pile, environment temperature. Detailed performance as follows:
A. Management host consists of black and white LED and managing calculator, first page displays of battery group total voltage and current、max voltage and battery number、min voltage and battery number; Second page displays capacity(adds while is charging, subtract while is discharging, save while power cut, clear)、consume Walt-hour、max temperature of all measuring points and min temperature; Press key display every battery voltage;
B. Sampling module adopts master-slave mode. Master sampling module manages ten batteries、one current and one temperature, slave sampling module manages ten batteries and one temperature.
C. The number of batteries that is managed by sampling module can be set from 1~N (N≤10) through management host, connection mode adopts N+1.
D. Master sampling module provides one sampling current, current sensor is current hall sensor.
E. Management host has two alarm interfaces, switch of voltage upper limit、aural and visual alarm, high temperature switch、aural and visual alarm、switch of over current、aural and visual alarm. Max voltage alarm and high temperature alarm share the same group interface, voltage lower limit alarm and over current alarm share the same group interface.
