When it comes to tracking SOC and SOH for a
BMS, measurements ultimately boil down to three
variables: voltage, current, and temperature. Each
variable individually provides useful insights into the
state and health of the battery, and the combination
of all three variables can paint a complete picture.
However, different specialized components are
needed to measure each variable.
For current sensing, the shunt resistor is the most
fundamental component. Shunt resistors are very
accurate, low-resistance components that utilize
VOLTAGE,
CURRENT, AND
TEMPERATURE
MEASUREMENTS
Energy Storage Systems on industrial and
commercial applications have demanding
lifetime requirements ranging between 15 and
20 years. BMS plays a crucial role in achieving
this by monitoring cell voltage, temperature,
and current to prevent issues such as
overcharging and overheating, thereby
extending the life of the batteries."
