Embodiment Construction

[0038] Now in conjunction with the accompanying drawings, the preferred embodiments of the present invention will be described in detail.

[0039] Such as figure 1 As shown, the present invention provides a preferred embodiment of a control method for a dual-battery charging system.

[0040] The control method of the dual-battery charging system includes the steps of:

[0041] S10, judging the status information of the charging device 10;

[0042] S20. If the first trigger condition is satisfied, control the charging device 10 to charge the second battery 30 with high power, otherwise, control the charging device 10 to charge the second battery 30 with low power;

[0043] S30, judging the state information of the first battery 20;

[0044] S40 . If the second trigger condition is met, control the first battery 20 to charge the second battery 30 with high power; otherwise, control the first battery 20 to charge the second battery 30 with low power.

[0045] By judging the s...

Abstract

The invention relates to the technical field of battery charging, in particular to a control method of a dual battery charging system. The dual battery charging system comprises a charging device, a first battery and a second battery. The control method includes the steps of judging the state information of the charging device, if the first trigger condition is satisfied, controlling the chargingdevice to charge the second battery with high power, otherwise, controlling the charging device to charge the second battery with low power; judging the state information of the first battery; if thesecond trigger condition is satisfied, controlling the first battery to charge the second battery with high power, whereas controlling the first battery to charge the second battery with low power. The invention can realize that both the charging device and the first battery can charge the second battery by charging with high power or low power, so that the energy of the charging device and the first battery is fully utilized, the output capacity of the system is improved, the waste of the charging energy is reduced, the performance-price ratio of the system is improved, and the hardware costis not increased.

Description

technical field [0001] The invention relates to the technical field of battery charging, in particular to a control method for a dual-battery charging system. Background technique [0002] In addition to the attributes of the vehicle, RVs and some special vehicles can also be equipped with daily life electrical appliances, as well as office equipment, such as computers, mobile communication terminals, air conditioners, TVs, refrigerators and other electrical equipment. [0003] In RVs and some special vehicles, there will be a main battery that can be used to start the electric vehicle, adjust the connection with the generator, and a secondary battery that supplies power to other electrical equipment. [0004] In a dual battery system formed of a main battery and a secondary battery, the main battery and the secondary battery need to be charged. In the existing dual-battery charging control system, two branches are set up to charge the auxiliary battery, one for the main ba...
