Problems solved by technology

see figure 1 and figure 2 , the installation sequence of the power cabinet is usually: start with the base assembly 03 at the bottom, then stack the battery modules 02 layer by layer, and finally install the power management module 01 at the top; in this installation sequence, each battery module 02 There is a voltage between the two poles of the connector port on the end face. Every time one battery module 02 is stacked, the stacked voltage will rise by a step; and the distance between the two poles of the connector port on the upper end face of the battery module 02 is relatively small. Small, during the installation process, the risk of electric shock to the human body is great

Abstract

The invention provides a stacked power supply cabinet. The stacked power supply cabinet comprises a top layer assembly and at least one battery module, in the stacked power supply cabinet, when the number of the battery modules is greater than 1 and the battery modules are stacked in sequence from top to bottom, the stacked battery modules establish an electrical connection path for external voltage, and conduction connection can be realized only through a power transmission line in the top layer assembly, so that electrification is realized; therefore, in the installation process of the stacked power supply cabinet, before the top layer assembly is installed, the stacked battery modules establish an electric connection path of external voltage to be uncharged, so that the risk of electricshock of a human body in the installation process of the stacked power supply cabinet is reduced, and the safety in the installation process of the stacked power supply cabinet is further improved.

Description

technical field [0001] The invention relates to the technical field of power electronics, in particular to a stacked power cabinet. Background technique [0002] With the rapid development of photovoltaic distributed energy storage systems, lithium batteries, which are an important part of photovoltaic energy storage batteries, are widely used in daily life and industrial production. However, the voltage of a lithium battery is too low to meet the needs of external devices, so usually multiple lithium batteries are connected in series to form a power cabinet with a voltage of several hundred volts to meet the needs of use; wherein each lithium battery is used as a battery mod. [0003] In engineering practice, the specific structure of the power cabinet is as follows: figure 1 As shown, its internal circuit principle is as follows figure 2 shown. see figure 1 and figure 2 , the installation sequence of the power cabinet is usually: start with the base assembly 03 at ...
