Summary: | A battery charging apparatus is configured to charge a battery with at least one of charging current and charging power set to a predetermined setpoint, wherein the battery includes a lithium secondary cell. The battery charging apparatus calculates a lithium deposition threshold voltage value based on the setpoint, wherein lithium is assumed to be deposited in the lithium secondary cell when a terminal voltage of the lithium secondary cell is above the lithium deposition threshold voltage value. Then, the battery charging apparatus compares the terminal voltage with the calculated lithium deposition threshold voltage value, and controls the at least one of charging current and charging power depending on the comparison. |
