Customer ServiceThe charging current electrolyzes the water from the electrolyte and both hydrogen and oxygen gas are produced this process called “gassing” of the battery. This gassing raises several problems in the battery. This is unsafe due to the explosive nature of hydrogen produced.
The constant voltage is applied till the current taken by the cell drop to zero, this maximizes the performance of the battery. Charge Termination:- The end of charging is detected by an algorithm that detects the current range that drops to 0.02C to 0.07C or uses a timer method.
Discharge Process: During the discharge process, the battery’s chemical reactions undergo a reversal. Lithium ions migrate from the negative electrode to the positive electrode, while electrons travel from the negative electrode to the positive electrode.
About 65% of the total charge is delivered to the battery during the current limit phase of charging. Assuming a 1c charging current, it follows that this portion of the charge cycle will take a maximum time of about 40 minutes. The constant voltage portion of the charge cycle begins when the battery voltage sensed by the charger reaches 4.20V.
The charging process involves introducing the charge (in this case, a high-quality gas) into the system when the working fluid is in the gaseous state at room temperature. For example, with cryogenic heat pipe fluid.
During charging of battery, external DC source is applied to the battery. The negative terminal of the DC source is connected to the negative plate or anode of the battery and positive terminal of the source is connected to the positive plate or cathode of the battery. The external DC source injects electrons into the anode during charging.
