A charger control method

Abstract

The invention discloses a charger control method. The method comprises steps of high-frequency setting in which a MCU chip sets a first clock frequency to be a working clock frequency, charging detection in which the MCU chip detects states of a charger and a battery pack, charging judgment in which the MCU chip judges whether charging is allowed at present, low-frequency setting in which the MCU chip sets a second clock frequency to be a working clock frequency, and low-frequency keeping in which the MCU chip waits for a preset time duration at the second clock frequency or in a clock closing state. The charger control method has the beneficial effects that the frequency of the working clock is adjusted in a non-charging stage, the percentage of the clock frequency reducing state or / and the clock closing state in the overall charging control process is improved, and power consumption is greatly reduced.

Description

technical field [0001] The invention relates to a charger control method, in particular to a charger control method capable of reducing energy consumption. Background technique [0002] With the enhancement of people's awareness of environmental protection and the prominence of environmental problems, various countries have put forward higher requirements on the energy consumption of electrical appliances and formulated more stringent energy consumption standards. [0003] As a commonly used electrical device, the charger is widely used in our daily life. It is the initial energy source of all electric tools using battery packs, so reducing its power consumption is of great significance. [0004] Among the existing charger technical solutions, one is implemented by pure hardware, which can also achieve lower standby power consumption, but the pure hardware circuit, function and user interface are relatively simple, and it is difficult to meet the diverse needs of customers. ...

Problems solved by technology

[0004] Among the existing charger technical solutions, one is implemented by pure hardware, which can also achieve lower standby power consumption, but the pure hardware circuit, function and user interface are relatively simple, and it is difficult to meet the diverse needs of customers.

Another technical solution is realized by combining hardware and software. Usually, a single-chip microcomputer is used in the circuit, and a single-chip microcomputer is used. In order to meet the needs of performance, a higher working clock is used, and the power consumption is also higher. It is difficult to achieve low standby power consumption as a whole

There is still no control method that can effectively reduce the standby power consumption of the charger
