4.5.4 Battery Module
The battery module consists of 60 electrochemical cells (three parallel strings,
each consisting of 20 cells connected in series). The electrochemical cells are made
of lithium iron phosphate. A built-in re suppression module is used. All external
ports are located at the front of the module for easy installation and maintenance.
Each battery module has a built-in battery management unit (BMU) that monitors
battery information such as voltage and temperature, provides relevant alarms,
and manages battery balancing. The BMU provides the following functions:
● Battery voltage measurement and alarm
● Battery temperature measurement and alarm
● Battery voltage balancing
● CAN communication between battery modules
