For Ni-Cd and Ni-MH battey: 1.Constant current(ab.CC) charge: it is the most usual method that charge currents are fixed at a certain value during the charge progress. 2.Constant voltage(ab.CV) charge: during the charge progress the voltage between the two terminals of the power supply is maintained at a certain value, while the current in the circuit become smaller and smaller with the battery voltage rises. 3. Constant current(ab.CC) and constant voltage(ab.CV) charge: firstly a cell is charged at CC, when the cell voltage rises to a value, its voltage keeps steady, while the current in the circuit drops to the smallest till to zero at last.
For Li-ion battery: Constant current(ab.CC) and constant voltage(ab.CV) charge: firstly a cell is charged at CC, when the cell voltage rises to a value, its voltage keeps steady, while the current in the circuit drops to the smallest till to zero at last. |
