By measuring the voltage across the battery, its remaining capacity can be preliminarily estimated. The constant current discharge method is a more accurate battery capacity test method. Connect the battery to a certain load and discharge it at a constant current until the battery voltage drops to the predetermined cut-off voltage.
The test method is to fully charge the battery at standard current with constant-current constant-voltage (CCCV). The schematic diagram of CCCV charging is shown in Fig. 2.11. After fully charging the battery, rest for a period of time and then discharge the battery with a constant current (CC) to the lower cutoff voltage.
The constant current discharge method is a more accurate battery capacity test method. Connect the battery to a certain load and discharge it at a constant current until the battery voltage drops to the predetermined cut-off voltage. By measuring the discharge time and combining the current value, the battery capacity can be accurately calculated.
At the same time, the end voltage change of the battery is collected to detect the discharge characteristics of the battery. Constant current discharge is the discharge of the same discharge current, but the battery voltage continues to drop, so the power continues to drop.
It helps evaluate the battery’s ability to handle peak loads. Capacity Load Test: This test determines the battery’s capacity by discharging it at a specific rate until it reaches a predefined voltage level. It provides insights into the battery’s usable capacity and helps estimate its runtime.
Here are some common types of load tests: Constant Current Load Test: This test applies a constant current load to the battery and measures its voltage response over time.
