How to test a battery?
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.
How to charge CCCV battery?
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 test will repeat three times.
How does a battery test work?
A load bank, voltmeters, and an amp meter will be utilized to discharge the battery at a specific current till a minimum voltage is achieved. The findings will be recorded across time intervals to determine whether the battery matches the required amp-hour rating according to discharge current & duration.
What happens when a battery reaches a voltage reference?
When the battery does reach the voltage reference, the voltage loop overrides the current loop and the battery current increases to zero. The direction of the current to charge or discharge the battery is controlled by a logic signal (indicated as “Direction” in Figure 2).
How to measure battery discharge capacity in electric vehicles?
Based on the requirements of Technical Conditions for Battery Management Systems in Electric Vehicles, it is necessary to measure the maximum discharge capacity of the battery three times in succession. The test method is to fully charge the battery at standard current with constant-current constant-voltage (CCCV).
What are the charge and discharge modes of a buckle battery?
