Example Embodiment

[0043] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the specific embodiments will be described in detail below in conjunction with the accompanying drawings.

[0044] figure 1 It is a flowchart of the steps of the method embodiment of the present invention, such as figure 1 As shown, the embodiment of the present invention provides a method for real-time control of automobile electrical balance, which includes the following steps:

[0045] Step 1. The controller obtains the real-time power value of the battery;

[0046] Step 2: According to the real-time power value of the battery, the controller judges whether it is necessary to charge the battery, if yes, proceed to the next step, otherwise the generator does not work and the process ends;

[0047] Step 3: The controller obtains the real-time load value of the engine;

[0048] Step 4. According to the real-time load value of the engine, the controller judges whether...

Abstract

The invention relates to automotive electric balance technology, in particular to real-time control method and device for automotive electric balance. The method includes the steps of firstly, acquiring real-time electric quantity of a storage battery; secondly, judging whether the storage battery needs to be charged or not according to the real-time electric quantity of the storage battery; thirdly, if yes, acquiring real-time load of an engine; fourthly, judging whether the engine is able to drive a generator to operate or not according to the real-time load of the engine; if yes, determining that the generator needs to operate and going to next step; fifthly, allowing the generator to operate; sixthly, acquiring real-time power of the generator and real-time electric consumption of an automobile; seventhly, judging decreasing or increasing the power of the generator is needed or not according to the real-time power of the generator and the real-time electric consumption of the automobile, and executing. Start and stop of the generator and operating efficiency thereof are controlled through the controller, so that real-time electric balance of the automobile is maintained.

Description

technical field [0001] The invention relates to automobile electric balance technology, in particular to a dynamic control method and device for automobile electric balance. Background technique [0002] At present, the electric balance of automobiles is preset according to the engine power, generator power, vehicle power consumption and battery capacity at the beginning of product design. Once the product is finalized, the electrical balance cannot be adjusted. However, due to the different electrical configurations of each car and the different operating conditions of the whole car, it will cause waste of power generation or power loss of the whole car, and will also cause deep discharge of the battery and reduce the life of the battery. Contents of the invention [0003] The purpose of the embodiments of the present invention is to provide a real-time control method and device for electric balance of automobiles, so as to solve the problem of electric power imbalance o...
