5.1.2 BMS functions
Main functions of the integrated Battery Management System (BMS) are:
Battery Thermal Management: battery needs to be warm before it starts receive or deliver
energy. The thermal management of the BMS performs the warm-up process automatically
as soon as it is powered.
Battery Charge Process: the BMS is equipped with a charge controller which is able to
regulate the charging parameters (voltage and current) in order to obtain the best charging
performance.
Battery Power/Energy Output Checks: the BMS calculate the battery SOC to provide a
reliable and safe operation and to avoid overcharge or over discharge.
Battery Operating Conditions Checks: the BMS continuously measures all the battery
parameters such as voltages, currents, temperatures, insulation levels providing a
continuous monitoring of the operating conditions.
Redundant Control: the controller is equipped with a safety redundant microprocessor
(Watchdog) for safe operations.
Battery communication: the BMS has various communication capability using different
communication ports: USB, RS485, optional CAN Bus or Ethernet.
