LITHIUM ION BMS

A BMS (Battery Management System) is essential in a Lithium-Ion battery system. This device manages a real-time control of each battery cell, communicates with external devices, manages SOC calculation, measures temperature and voltage, etc.

TECHNICAL DETAILS:

Voltage: minimum and maximum cell voltage
State of charge (SOC) or depth of discharge (DOD), to indicate the charge level of the battery
State of health (SOH), a variously-defined measurement of the remaining capacity of the battery as % of the original capacity
State of power (SOP), the amount of power available for a defined time interval given the current power usage, temperature and other conditions
State of Safety (SOS)
Maximum charge current as a charge current limit (CCL)
Maximum discharge current as a discharge current limit (DCL)
Energy [kWh] delivered since last charge or charge cycle
Internal impedance of a cell (to determine open circuit voltage)
Charge [Ah] delivered or stored (sometimes this feature is called Coulomb counter)
Total energy delivered since first use
Total operating time since first use
Total number of cycles
