Dimension

260 x 158 x 246 mm

Approximate Weight

15.1kg

Nominal voltage

12.8V

Maximum voltage

14.6V

Minimum voltage

10.0V

Discharge current

150A max. continuous current @ 23° C

Peak discharge current

300A max for 30 sec @ 23° C

Charge protection

When the Battery modules are charged to full, they will communicate with BMU, and the BMU has the capability to turn off the charger or open the main contactor. The battery module itself does not have any switch to disconnect the charger.

Cell Balancing

The intra-module balancing circuitry is used to compensate slight capacity imbalance among the four cell banks within a battery module.

The inter-module balancing circuitry is used to compensate slight capacity imbalance between different battery modules in series connection.

State of Charge Measurement

Individual cell bank voltage and charge/discharge current will be used to monitor the state of charge (SOC) of the battery module. The estimated capacity used for the calculations will be adjusted to meet the capacity of the lowest capacity cell bank when the pack is fully cycled.  The state of charge will be adjusted for normal self discharge of the pack when the unit is not on charge.    

RS-485 Uplink

RS-485 Communications will be used to communicate with the Battery Management Unit (BMU) or connection to other battery Modules. 

RS-485 Downlink

RS-485 Communication connection from Downstream battery module.

RS-485 insulation voltage rating

1414V

5000V rms for 1 minute

Status LED

A Dual LED on module to indicate working status. One is green and the other one is red. Blinking of the green LED indicates that the module is working properly. Blinking of the red LED indicates that the module has failure and needs service.
