Description

Technical Field

[0001] This utility model relates to the field of energy storage battery technology, specifically to a high-safety rechargeable battery home energy storage module. Background Technology

[0002] Home energy storage battery modules are used to improve home energy self-sufficiency, especially in the context of the increasing popularity of renewable energy sources such as solar and wind power.

[0003] Specifically, a home energy storage battery module is an integrated battery system, typically composed of multiple battery cells, capable of storing electrical energy from renewable energy systems such as solar panels. Its main functions include:

[0004] Energy storage: storing electrical energy when electricity demand is low or electricity prices are cheap, so that it can be used when demand is high or electricity prices are high;

[0005] Power dispatching: Intelligent dispatching of power usage based on household electricity demand and electricity price changes.

[0006] Emergency power supply: Provides backup power during power outages to ensure that basic household electricity needs are met.

[0007] The components of a home energy storage battery module include battery cells, a battery management system (BMS), an inverter, and a control system, with the battery cells being the main component.

[0008] The battery cells are assembled using a series-parallel connection and then encapsulated inside the casing. After the battery cells are connected in series and parallel, both the positive and negative terminals are exposed. The distance between the positive and negative terminals is relatively short, and the casings for home energy storage are generally metal. During operation, metal tools and metal screws are used for tightening, which can easily cause short circuits in the modules, posing a serious safety hazard. Utility Model Content

[0009] The purpose of this invention is to provide a highly safe rechargeable battery home energy storage module, which features high safety, convenient installation, and low cost.

[0010] This utility model can be achieved through the following technical solutions:

[0011] This utility model discloses a high-safety rechargeable battery home energy storage module, including a box, in which several battery units are arranged. The battery units are fixed inside the box by insulating strips. The surface of the insulating strips is provided with positioning posts, and insulating partitions are installed on the positioning posts. The insulating partitions provide safety protection for the positive and negative terminals of the battery units.

[0012] Furthermore, the insulating partition is made of plastic sheet, which is injection molded, and the material is widely available and has low processing costs.

[0013] Furthermore, the plastic sheet can be a phenolic resin sheet, PP sheet, PE sheet, PET sheet or PVC sheet, which can be flexibly selected according to actual needs.

[0014] Furthermore, there are several positioning posts, which are evenly spaced and at the same height on the insulating pressure strip, which effectively fixes the insulating partition plate and ensures the integrity of the coverage.

[0015] Furthermore, the insulating partition plate is detachably fixed to the positioning post by screws or fasteners, simplifying the installation and fixing process.

[0016] Furthermore, the number of battery cells is several, and these battery cells are assembled from battery cells through series and parallel connections. The structural design is relatively flexible and meets the usage requirements.

[0017] Furthermore, the insulating separator is larger than the mounting area of ​​several battery cells and fully covers the areas where the positive and negative electrodes of the battery reaction are located, effectively ensuring safety.

[0018] Furthermore, the battery cell is a square cell, which is an aluminum-plastic film cell or an aluminum shell cell, making it convenient for fixed installation.

[0019] Furthermore, the battery cell is a lithium-ion battery cell, which may be a lithium manganese oxide battery cell, a lithium cobalt oxide battery cell, a lithium iron phosphate battery cell, or a ternary material battery cell.

[0020] Furthermore, the battery cell is a sodium-ion battery cell, which is a polyanion battery cell, a layered oxide battery cell, or a Prussian blue material battery cell.

[0021] This utility model discloses a highly safe rechargeable battery home energy storage module, which has the following beneficial effects:

[0022] First, it has high safety. By setting positioning posts on the pressure strip and installing insulating partition plates on the positioning posts, the positive and negative terminals of the originally exposed battery cells are effectively covered and insulated to avoid the risk of short circuit and effectively improve the safety of the battery module.

[0023] Secondly, it is easy to install. The installation of the insulating partition plate only requires the design of a positioning column structure on the original insulating pressure strip. There is no need to make complicated modifications to the original box structure, which effectively improves the convenience of installation.

[0024] Third, it is inexpensive. The fixing structure of the insulating partition is relatively simple, and the choice of material, such as commercially available plastic boards, can meet the insulation requirements, effectively reducing its manufacturing and processing costs.
