Problems solved by technology

At present, the charging interface module of the charger is exposed. Since the general battery pack is a low-voltage battery pack, the exposed charging interface module usually does not cause serious electric shock accidents to the human body; but when the battery pack is a high-voltage battery pack, the exposed There will be high voltage on the charging interface module, which is easy to cause electric shock accidents

Embodiment Construction

[0030] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0031] Such as figure 1 As shown, the charging method applied to the high-voltage battery pack is specifically: setting an on-off circuit for controlling the main power module in the charger;

[0032] The specific charging steps are as follows:

[0033] 1) The charger is connected to the AC power supply, the auxiliary power module is working, the main power module is not working, and the charging interface has no high-voltage output;

[0034] 2) Insert the battery pack into the charger, the on-off circuit is turned on, and a conduction signal is generated to make the main power module work, and the charging interface outputs high voltage;

[0035] 3) After the charging is completed, the high-...

Abstract

The invention discloses a charging method applied to a high-voltage battery pack. An on-off circuit for controlling a main power supply module is arranged in a charger; the charging method comprises the steps as follows: the charger is connected to an alternating current power supply; an auxiliary power supply module works and a main power supply module doest not work; and a charging interface has no high-voltage output; the battery pack is inserted into the charger, and the on-off circuit is switched on to generate a switch-on signal to enable the main power supply module to work, and the charging interface outputs a high voltage; after the charging process is completed, the high-voltage battery pack is pulled out; and the on-off circuit is switched off to generate a switch-off signal to enable the main power supply module not to work, and the charging interface has no high-voltage output. Meanwhile, the invention also discloses the charger applied to the high-voltage battery pack. The charger comprises the auxiliary power supply module, the main power supply module, an MCU, a PNP triode Q1, the charging interface and the on-off circuit. According to the charging method and the charger, hardware and software dual protection is achieved, so that electric shock risk of a user is effectively lowered, and related safety standard and requirement are satisfied; and meanwhile, the scheme is simple, safe and reliable, and low in realization cost.

Description

technical field [0001] The invention relates to a charging method and a charger applied to a high-voltage battery pack, belonging to the technical field of charging. Background technique [0002] The battery pack is a common power module, which is charged by a charger. The current charger mainly includes an auxiliary power module and a main power module. The main power module is used to convert external AC power, and the output to the battery pack meets the requirements. The voltage; the auxiliary power supply provides power for each module in the charger. At present, the charging interface module of the charger is exposed. Since the general battery pack is a low-voltage battery pack, the exposed charging interface module usually does not cause serious electric shock accidents to the human body; but when the battery pack is a high-voltage battery pack, the exposed There will be high-voltage electricity on the charging interface module, which is prone to electric shock accid...
