Embodiment Construction
[0040] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing the embodiments is to make the disclosure of the present invention more thorough and comprehensive.
[0041] It should be noted that when an element is referred to as being “fixed on” another element, it may be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of illustration only. ...

An energy storage buffer control method and control system, the energy storage buffer circuit includes an engine, a generator, a power battery, a charge and discharge controller, a buffer module and a load, the engine is connected to the generator, and the three control terminals of the charge and discharge controller It is respectively connected to the power battery, the generator and the load, and the buffer module is connected in parallel at both ends of the load. The energy storage buffer control method includes: real-time detection of the current demand power of the load; when the current demand power is less than the optimal output power of the engine, Detect the power of the power battery; when the power of the power battery is not full, control the engine to work according to the optimal output power, and control the output of the generator to pulse between the load and the power battery according to the first duty cycle through the charge and discharge controller mode switching, the first duty cycle is the ratio of the time when the load is connected to the generator in one control cycle to the time of the control cycle.
Description
technical field [0001] The invention relates to the technical field of automobiles, in particular to an energy storage buffer control method and a control system. Background technique [0002] In many places in life, it is necessary to use a mobile power supply device to provide electric energy, and the power supply device is generally powered by a generator driven by an internal combustion engine. The engine can only achieve high-efficiency electrical energy conversion under the highest thermal efficiency. With the increasing requirements of energy and environment, improving the power conversion and utilization efficiency of traditional generators under different loads, and achieving high energy efficiency utilization and low emission thermal generator technology have attracted more and more attention. [0003] In the existing power supply device, when the required power of the load matches the optimal output power of the engine, the engine maintains the optimal output pow...
