♦Data Collection Module (DCM) Dscription

DCM connects a battery module, along with temperature sensors. It is used to cllection battery voltage, temperature of the battery module and other information. 1 piece of DCM can monitor 1~16serial batteries. Each DCM attaches 2 or more pieces of temperature sensors. Meanwhile the DCM has balancing functions. when any single cell’s voltage reaches 3.55V, and the voltage diffierence is 20mV~800mV, the balance function will start working. And the DCM balances three cells each time.

♦Insulation Test Module (ISO) Function

The function of Insulation Test Module is to detect whether the batteries leakage to the car or not. It connects to Data Collection Module and receives commands from Central Module. Meanwhile the Insulation collection data and information and send the information and data to Central Control Module. Finally this data and information will be displayed by the screen.

♦Status Instructions

There are three lights on the screen that indicate the status of the operation of the system. including power light (PWR), Running (RUN), communication (COM). When the screen is powerded on, the PWR light will be always bright; if the RUN light is always bright, it means the screen is running fine; if the RUN light is dark, it means the scree has someting wrong; if the EMS is connected, COM light is flash yellow.
