Battery SOH and SOC monitoring system

Dynamic SOH (State of Health) detection performs a comprehensive analysis of the battery’s internal parameters. It provides real-time and accurate estimation of the current battery capacity, overcoming errors caused by the false voltage effect common in lead-acid batteries. This offers reliable data to prevent overcharging and addresses the nonlinearity between battery capacity and voltage, giving users a clear and accurate understanding of the battery system’s charge status and operating condition.

Output information

No. Item Description
1 Total Voltage (V) Battery pack voltage. Available system options: 24V, 36V, 48V, 60V, 72V, 84V, 96V, 114V (customizable upon request).
2 State of Charge (SOC) Current battery pack remaining capacity, displayed as a percentage % (or +Ah).
3 State of Health (SOH) Indicates the maximum energy (capacity) the battery can store. If capacity drops below 50%, maintenance or replacement is required. Display format: percentage % (+Ah). 100% = rated capacity.
4 Charging Current Based on battery capacity, the charging current and capability vary. Range: 1–100A.
5 Discharging Current Represents the discharge capability of the battery pack. Range: 1–500A.
6 Energy (kWh) Total energy output accumulated from the battery pack. (Optional)
7 Power (kW) Output power of the battery pack. (Optional)
8 Temperature (°C) Two temperature measurement points.
