Our company product and supply the solution that proper to battery pack, battery module and battery cell used in EV, hybrid automotive, Motorcycle using battery and forklift. To get more information, please refer to Battery test system.
Example for battery pack, battery module and battery cell (Module and pack based on flat cell. series¶llel connection)
Example for battery pack, battery module and battery cell (Module and pack based on core cell. series¶llel connection)
Battery pack internal resistance: This is measued as follow. Total battery internal resistance = battery pack resistance + other resistanc(PCBA + wire…etc.).
Battery operation/protection: Protect with OVP/UVP within SOC 100%~0% and set operation range from SOC 80% ~ 20%.
SOC: State of Charge
Parameter – Voltage, Current, Temperature, Usage age, Electric Material
OCV: Open Circuit Voltage
By producing the system as follow, this acquire data by communicating with battery’s BMS and can test reliability, durability, life, environmental condition and etc with various
Test life and capacity with Battery Simulator as below.
