Problems solved by technology

[0002] Most of the existing charging technologies for emergency start-up power supplies for automobiles or supporting products for drones use low-current constant-current charging, which takes a long time to charge, and the original charger must be used for safety reasons, which will cause inconvenience to users
Charging is slow, and it cannot replace charging is its obvious shortcoming, especially when the car's emergency start-up power supply or the drone is out of power or low in power, and it happens to be urgently needed at this time, there is a fast and safe charging method Or emergency charging is necessary

Embodiment 1

[0082] Embodiment 1: as Figure 12-13 , a mobile power supply timing charging method, when the charging starts, start the timer, when the preset timing time of the timer arrives, control the charging circuit to disconnect, and stop charging.

[0083] The timer is a timer integrated in the MCU in the mobile power supply; the timer is started by the MCU, and when the preset timing time of the timer arrives, the MCU controls the charging switch to disconnect and stop charging.

[0084] The timer is a mechanical timer, and the mechanical timer is connected in series in the charging circuit.

[0085] Said charging refers to direct charging. Direct charging refers to charging the battery by directly loading the DC voltage through the charging switch; there are two preferred methods: (1) use the 12V DC voltage of the car cigarette lighter port to charge the battery; (2) obtain DC voltage from the mains through a transformer and a rectifier , the battery is charged by this DC voltag...

Abstract

The invention discloses a method for timed charging of a mobile power source. Before charging begins, a timer is started, when a preset timing time of the timer arrives, a charging circuit is controlled to be switched off, and charging is stopped. The timer is a time integrated in an MCU in a mobile power source; and the MCU starts the timer, when the preset timing time of the timer arrives, the MCU controls a charging switch to be switched off, and charging is stopped. The MCU in the mobile power source is also connected with a battery electric quantity detection module; and if it is detected that a battery is full before the time of the timer arrives, charging is automatically controlled to end through the charging switch. The MCU in the mobile power source is also connected with a temperature detection module; and if it is detected that battery temperature or temperature in the mobile power source reaches a preset value before the time of the timer arrives, charging is automatically controlled to end through the charging switch, wherein the preset value is a certain value from 55 DEG C to 75 DEG C. The method for timed charging of the mobile power source has the characteristics of quick charging and high safety.

Description

technical field [0001] The invention relates to a method for timing charging of a mobile power supply. Background technique [0002] Most of the existing charging technologies for emergency starting power supplies for automobiles or supporting products for drones use low-current constant-current charging, which takes a long time to charge, and the original charger must be used for safety reasons, which will cause inconvenience to users. Charging is slow, and it cannot replace charging is its obvious shortcoming, especially when the car's emergency start-up power supply or the drone is out of power or low in power, and it happens to be urgently needed at this time, there is a fast and safe charging method Or emergency charging is necessary. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a mobile power supply timing charging method, which has the characteristics of fast charging and high safety. [0004] The tec...
