Quick charge method and system

The invention is suitable for the field of a mobile terminal and provides a quick charge method and system. A second controller sends a quick charge request to a first controller; the first controller feeds back a quick charge permission instruction to the second controller; the second controller sends a notification request for obtaining voltage value of a battery core to the first controller; the first controller obtains the voltage value of the battery core through a battery core connector and sends the obtained voltage value of the battery core to the second controller; the second controller finds out a current regulation instruction matched with a threshold value range where the voltage value of the battery core locates from a threshold value range table, and sends the current regulation instruction to a regulator circuit; and the regulator circuit carries out current regulation according to the current regulation instruction, and outputs a power supply signal after current regulation. Therefore, before the battery core of the mobile terminal is subjected to quick charge, the mobile terminal is asked whether to accept quick charge; and in the charging process, the charging current is controlled, thereby effectively preventing the battery core from being charged excessively.

An active equalizing system and an equalizing method of power lithium ion battery

The invention relates to an active equalizing system and an equalizing method of power lithium ion battery. The equalizing system comprises a battery module, which is connected with an input end of an equalization controller through a battery pack voltage sampling module; any single battery in the battery module is connected with the input end of the equalization controller through a single battery voltage measuring module and is connected with an electric quantity equalizing module, which is connected with the input end of the equalization controller; and when the single battery voltage values and an average voltage value of the single batteries in the battery module correspond to the voltage relations preset by the equalization controller, the equalization controller outputs equalizing control signals to the electric quantity equalizing module and realizes the active equalization of the corresponding single batteries in the battery, thereby making the single battery voltages and the average voltage value of the single batteries in the battery module match the voltage relation preset by the equalization controller. The active equalizing system and equalizing method are convenient for usage and operation, capable of prolonging the service lifetime of the battery, highly flexible, safe and reliable.

Battery protection circuit, electric energy supply device and electronic device

The invention discloses a battery protection circuit, an electric energy supply device and an electronic device. The battery protection circuit is externally connected with a battery and comprises a battery protection chip for providing protection control signals to the battery, and the battery protection chip at least comprises a positive chip power supply input pin. The battery protection circuit further comprises a chip control switch which is arranged between the positive chip power supply input pin and the positive electrode of the battery and configured as the connected or disconnected status in a controlled way; when the chip control switch is in the connected status, the positive chip power supply input pin of the battery protection chip is connected with the positive electrode of the battery, so that the battery protection chip begins to operate; when the chip control switch is in the disconnected status, the positive chip power supply input pin of the battery protection chip is disconnected with the positive electrode of the battery, so that the battery protection chip stops to operate. Through the solution, the battery is excessively discharged because the battery protection chip consumes power, the service life of the battery is prolonged.
