Car Battery Charging Method

The operation process of the car battery to convert the electrical energy of the external circuit into the storage battery into chemical energy and store it. Charging rate: the current value required to charge the battery to the rated capacity within a specified time, or the time required to charge to the rated capacity at a certain current. Similar to the discharge rate, it is generally expressed by the rate (several C) or time rate. Constant voltage charging: A charging method that keeps the voltage at the charger end constant while the car battery is charging. Constant current charging: A charging method in which the charging current remains unchanged while charging. Polarization: Polarization is the change in battery voltage and electrode potential caused by the battery changing from a static state (current i = 0) to a working state (i> o).

The product of voltage and current is equal to power, and then multiplied by the battery running time is the output power, so the polarization phenomenon reflects the energy loss from the static state to the working state, so the smaller the polarization loss, the better. Common polarization phenomena include anode polarization, cathode polarization, ohmic polarization (resistance polarization), concentration polarization and electrochemical polarization. The polarization phenomenon can also be understood as a deviation from the equilibrium phenomenon. The thermodynamic equilibrium process is closely related to the reversible phenomenon. The rate of change of the reversible process or the equilibrium process is very small, but the actual process must have a certain rate, and sometimes a high rate is required.
