Discharging method, charging device, computer storage medium and mobile power supply

Abstract

The invention discloses a discharge method, charging equipment and computer storage medium, comprising: detecting the output current of the charging equipment; when the output current is less than the first critical current, controlling the output voltage of the charging equipment to be the rated output voltage of the charging equipment The sum of ΔU1 and ΔU1; when the output current is equal to or greater than the first critical current, the output voltage of the charging device is controlled to be the sum of the rated output voltage and ΔU2, ΔU1 and ΔU2 are positive numbers and ΔU2 is greater than ΔU1. The discharge method, charging device and computer storage medium provided by the present invention control the output voltage of the charging device to be additionally increased on the basis of the rated output voltage according to the output current of the charging device, so as to realize the compensation of the charging voltage actually obtained by the electric device , the charging voltage actually obtained by using the electric equipment is basically consistent with the rated output voltage of the charging equipment, which can solve the problem that the actual output power of the charging equipment for charging the electric equipment is inconsistent with the required power of the electric equipment.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a discharge method, a charging device and a computer storage medium. Background technique [0002] With the popularity of mobile electronic equipment and other electrical equipment, people's lives are greatly facilitated, and with the increasing battery capacity of today's mobile electronic equipment, the traditional 5V / 1A charging power can no longer meet the demand, more and more More and more electronic devices are beginning to support fast charging technology. In this context, charging devices that support high-current discharge such as mobile power banks that support fast charging functions have emerged as the times require. [0003] However, when traditional charging equipment such as adapters and mobile power supplies charge electronic equipment, due to the loss of charging cables and charging interfaces, the actual charging voltage obtained by electronic equipment is...

Problems solved by technology

[0003] However, when traditional charging equipment such as adapters and mobile power supplies charge electronic equipment, due to the loss of charging cables and charging interfaces, the actual charging voltage obtained by electronic equipment is lower than the output voltage of the charging equipment, and the reduction in voltage It will increase with the increase of charging current, which will cause the actual output power of the charging device to charge the electric device to be inconsistent with the demand power of the electric device

For example, when a mobile power supply with a large current discharge is used to charge an electronic device, since the actual charging voltage obtained by the electronic device will be significantly lower than the output voltage of the mobile power supply, the charging management chip of the electronic device will think that the load of the mobile power supply is insufficient , thus greatly reducing the output power of the required mobile power supply, so that the actual output power of the mobile power supply charging the electronic device is significantly lower than the required power of the electronic device
