6 FAQs about [Battery controller current parameter table picture]
How is current measured in a battery pack?
Current is measured by a low-side shunt resistor. Battery pack current, temperature and cell’s voltage determine state of charge (SOC). State of health (SOH) is determined by comparing cell’s current parameters with the parameters of a new battery pack. The BMS default HW parameters are listed in Table 1.
What determines a battery pack state of charge (SOC)?
Battery pack current, temperature and cell’s voltage determine state of charge (SOC). State of health (SOH) is determined by comparing cell’s current parameters with the parameters of the new battery pack. The BMS default parameters are listed in Table 1.
How is a battery pack temperature monitored?
Battery pack’s temperature is monitored by Dallas DS18B20 digital temperature sensor/s. Current is measured by a low-side shunt resistor. Battery pack current, temperature and cell’s voltage determine state of charge (SOC). State of health (SOH) is determined by comparing cell’s current parameters with the parameters of a new battery pack.
What is the state of charge of a battery module?
At the start of the simulation, the battery module has a state of charge (SOC) of 10%. The Battery CC-CV block performs a constant-current (CC) charging until it reaches the limit cell voltage of 4.1 V specified in the Maximum cell voltage (V) parameter.
How does a battery balancing algorithm work?
When the battery is discharging, the model uses a constant current. Balance a battery with two cells connected in series by using a passive cell balancing algorithm. The initial state-of-charge (SOC) for the two cells are equal to 0.7 and 0.75. The balancing procedure depends on the cell voltages.
How does a battery balancing system work?
The BMS equalizes cells’ voltage by diverting some of the charging current from higher voltage cells to the whole pack or from the whole pack to a lower voltage cells – active balancing. The device’s temperature is measured to protect the circuit from over-heating due to unexpected failure.
