Problems solved by technology

[0002] Most of the existing charging technologies for emergency start-up power supplies for automobiles or supporting products for drones are 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

[0085] Embodiment 1: as Figure 12-13 , a mobile power supply based on timing charging. When charging starts, a timer is started. When the preset timing time of the timer arrives, the charging circuit is controlled to be disconnected and charging is stopped.

[0086] 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.

[0087] The timer is a mechanical timer, and the mechanical timer is connected in series in the charging circuit.

[0088] 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) the 12V DC voltage of the car cigarette lighter port is used to charge the battery; (2) the 220V AC voltage is obtained through a transformer and a rectifier in turn The DC voltage...

Abstract

The invention discloses a mobile power supply based on timing charging, which comprises an input end interface, a voltage conversion circuit, a charging switch, a battery pack, a control unit and a timer, wherein the input end interface, the voltage conversion circuit, the charging switch and the battery pack are sequentially connected; the charging switch is controlled by the control unit; when charging begins, the timer is started, when the preset timing time of the timer arrives, the charging circuit is controlled to be cut off, and charging is stopped. The MCU inside the mobile power supply is also connected with a battery power detection module. If the battery is detected to be fully charged before the time of the timer arrives, the charging is automatically controlled to be over through the charging switch. The MCU inside the mobile power supply is also connected with a temperature detection module. If the battery temperature or the temperature inside the mobile power supply is detected to reach a preset value before the time of the timer arrives, the charging is automatically controlled to be over through the charging switch. The mobile power supply based on timing charging has the advantages of quick charging and high safety.

Description

technical field [0001] The invention relates to a mobile power supply based on timing charging. Background technique [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 may 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 based on timing charging, which has the characteristics of fast charging and high safety. [0004] The technical...
