Specificaton of Battery Management System
BMS
Voltage | Measures voltage of individual batteries which helps users determine the health and performance of the batteries. |
Current | Measures the amount of current which flows through each battery bank during the float, charge and discharge mode, as this enables the user to optimize the current flow in the system. |
Battery Temperature |
Monitors the ambient temperature which helps the user in detecting and preventing incorrect temperature levels, which allows for an increase in the battery life.
|
Ambient Temperature | Measures the individual battery temperature to prevent thermal runaway and overheating. |
Capacity | Indicates the battery capacity in percentage, which helps one determine
the power of every block.
