Problems solved by technology
[0004] However, the existing photovoltaic lithium battery system still has deficiencies in the energy storage link. In terms of power transmission and energy storage, it cannot automatically balance the voltage of each battery. Therefore, it is necessary to develop a new type of energy storage cabinet to solve the problem of shortened battery life due to unbalanced batteries

Embodiment Construction
[0032] 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. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention may be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.
[0033] In addition, an element in the present invention is said to be "fixed" or "disposed on" another element, and it may be directly on another element or an intervening element may also exist. 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 pur...

The invention relates to photovoltaic power generation energy storage equipment, in particular to a photovoltaic energy storage cabinet, which is characterized in that an inverter, a host and a plurality of superposed battery modules are sequentially mounted in a cabinet body from top to bottom, and the host is connected with the battery modules through a mobile charging mechanism; the mobile charging mechanism comprises two chain wheels rotationally installed in the cabinet body and a chain used for connecting the two chain wheels, the chain is arranged in the height direction of the cabinet body, and a charging assembly in butt joint with the battery module is arranged on the chain; the power device drives the redirection assembly to work, the redirection assembly drives the walking assembly to operate, and the walking assembly drives the chain wheel connected with the walking assembly to intermittently rotate, so that the charging assemblies on the chain are in butt joint with the stacked battery modules one by one, and power is equivalently transmitted to the battery modules one by one; and after the charging assembly transmits power to the multiple battery modules one by one, the direction changing assembly changes the running direction of the walking assembly, so that the chain wheel rotates discontinuously in the reverse direction, and then the charging assembly transmits power to the multiple battery modules equivalently in the reverse direction one by one.
Description
technical field [0001] The invention relates to a photovoltaic power generation energy storage device, in particular to a photovoltaic energy storage cabinet. Background technique [0002] With the attention of human beings to clean energy, the development prospect of photovoltaic lithium battery is immeasurable. Photovoltaic lithium battery technology directly converts the sun's light energy into electrical energy, which is an inexhaustible and environmentally friendly energy. [0003] The photovoltaic lithium battery system is basically composed of photovoltaic inverters, photovoltaic modules, several battery modules connected in series, energy storage cabinets, battery management hosts, etc. Most of the current photovoltaic systems also use lead-acid batteries as energy storage devices. But in comparison, lithium iron phosphate battery replacement can give full play to its advantages, including improving energy storage efficiency, prolonging service life, reducing unit co...
