Problems solved by technology
[0004] This solution only restricts reverse charging from the perspective of wired reverse charging, does not involve the field of wireless charging, and meets certain conditions to forcibly stop reverse charging, without active selection design. In addition, this solution only controls reverse charging conditions. The limit is set, and the situation that the power supply device is exhausted and the power receiving device receives little power is not considered

Embodiment Construction
[0016] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments:
[0017] like figure 1 The reverse charging control system shown in the figure includes a power supply end (such as a car, a mobile phone, a Bluetooth speaker, etc.) and a power receiving end (such as a car, a mobile phone, a Bluetooth speaker, etc.), and the power receiving end includes a signal transmission module 1 and a charging capacity setting module. 2. The power supply terminal includes a signal receiving module 3, a charging time calculation module 4, a control module 5 and a power consumption calculation module 6, wherein the signal transmission module 1 is used for receiving the power preset by the charging amount setting module 2. The terminal demand power Q1 is transmitted to the signal receiving module 3, and the signal receiving module 3 transmits the receiving terminal demand power Q1 to the charging time calculation mod...

The invention discloses a reverse charging control system which comprises a power supply end and a power receiving end, the power receiving end comprises a signal transmission module and a charging amount setting module, and the power supply end comprises a signal receiving module, a charging time calculation module, a control module and a power consumption calculation module. By actively setting the required electric quantity of the power receiving end, calculating the required charging time and the consumed electric quantity of the power supply end according to the required electric quantity of the power receiving end, and judging whether a reverse charging condition is met, the situation that reverse charging is forcibly stopped when the electric quantity of the power supply end is lower than a certain value is avoided, and whether reverse charging is carried out can be actively selected; meanwhile, by calculating the consumed electric quantity of the power supply end meeting the demand electric quantity of the power receiving end, the situation that the power receiving end obtains little electric quantity due to the fact that the electric quantity of the power supply end is exhausted, namely the charging efficiency is too low can be actively avoided.
Description
technical field [0001] The invention relates to the technical field of battery charging and discharging, in particular to a reverse charging control system and a control method. Background technique [0002] The reverse charging technology is becoming more and more mature, but due to the low charging efficiency, the reverse charging consumes a lot of power at the power supply end, so it is necessary to control the reverse charging to determine whether the reverse charging conditions are met; in addition, due to the reverse charging If the loss is large, there will be cases where the remaining power at the power supply end cannot meet the needs of the power receiving end, resulting in the power supply end consuming all the power, and the power receiving end getting very little power. [0003] Patent CN 108808798A provides a method and device for reverse charging. In this patent, the power supply terminal and the power receiving terminal are in a connected state. The method in...
