Analysis of the calculation method of lithium battery charging time

The theoretical charging time of a lithium battery is the ratio of the nominal capacity of the battery to the current: lithium battery charging time (h) u003d battery capacity (mAh) u0026 pide; charging current (mA) because impedance occurs during charging, in order to offset the impedance The actual charging time is longer than the above theoretical charging time. In order to make the lithium battery charging time meet the actual full-charge requirement, a factor greater than 1 is generally set according to the ratio of the charging current to the battery capacity. Lithium battery charging time (hours) u003d rechargeable battery capacity (mAh) / charging current (mA) * 1.5 coefficient. If you use a 1600mAh rechargeable lithium battery and the charger uses a current of 400mA to charge, the charging time is: 600/400*1.5u003d6 hours (note: this method does not apply to newly purchased or long-term unused rechargeable batteries) portable electronic products The charging time of the lithium battery is also specified in accordance with the above formula. These lithium batteries are generally equipped with corresponding constant current chargers. The operation of this lithium battery charger on the charging time of the lithium battery is declared by the full battery indicator. , When the battery is overcharged, an alarm signal will be issued, so consumers only need to follow the instructions and do not have to worry about how long the lithium battery is charged. In practice, the charging time of the lithium battery is longer than the theoretical time because of the energy consumption during charging. The increase of the charging voltage can increase the charging power. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
