LiFePO4 Battery Pack BMS Performance
1.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.
2.Balancing
The inter-module balancing circuit is used to compensate slight
capacity imbalance between different battery modules in series
connection.
3.State of Charge Measurement
Individual cell block 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 block when the
battery system is fully cycled. The state of charge will be
adjusted for normal self discharge of the battery system when the
unit is not on charge.
4.RS-485 Communication Uplink
RS-485 Communications will be used to communicate with the Battery
Management Unit (BMU) or connection to other battery Modules.
5.RS-485 Communication Downlink
RS-485 Communication connection from Downstream battery module.
6.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.
Application
- Communication and signal systems such as telecommunication,
- solar light , solar lamp ,
- Electric power system and nuclear power plant, energy storage of
solar and wind power generation; e-v and E-car
- UPS, medical equipment, and emergency illumination etc.
