Description

Technical Field

[0001] The present invention relates to the field of battery technology, and in particular to a low-voltage battery energy storage module. Background Art

[0002] With the improvement of the living standards of the national economy and the popularization of electric vehicles, the consumption of electricity is gradually rising. The speed of power grid construction can no longer meet the growth of electricity consumption. A method and device to quickly solve the bottleneck of electricity consumption is needed. In fact, the peak of urban electricity consumption only lasts for more than an hour and then quickly declines to a stable state. The main reason is that catering, air conditioning, and online car-hailing charging lead to local energy shortage.

[0003] The low-voltage distributed modular energy storage device adopts a standardized and miniaturized approach to disperse the energy storage modules to every corner of the city. The energy storage device connects data with the integrated energy management platform through the 4G network. The integrated energy management platform also connects data with the dispatching platform of the power company, and the dispatching platform of the power company has the highest command authority. When the load is not tight, the cost is recovered through the peak-valley power difference. When the load is tight, the dispatching platform can issue dispatching instructions to the integrated energy management platform through the network. After receiving the dispatching instructions from the power dispatching platform, the integrated energy management platform stops the peak-valley power difference instructions and starts to unify the instructions of the corresponding power dispatching platform. In the case of insufficient load, energy is released by responding to remote dispatching to meet the load demand of national production and life in local areas and achieve the purpose of peak regulation. When the load is insufficient at night or the solar photovoltaic power generation is too large, energy is absorbed to achieve the purpose of valley filling.

[0004] Since the low-voltage distributed energy storage module is small in size (length, width and height are 2000*1000*2000mm) and has a small unit capacity (single module is 120KW / 220Kwh or 50Kw / 110Kwh), it can be dispersed to the open space within each enterprise and connected by low-voltage cables. Dozens or even hundreds of modules can be arranged in local areas for unified scheduling to effectively regulate the electricity demand in the local area.

[0005] A battery refers to a cup, trough or other container or part of the space of a composite container that contains an electrolyte solution and metal electrodes to generate electric current. It is a device that can convert chemical energy into electrical energy and has a positive electrode and a negative electrode.

[0006] According to the "A Low Voltage Battery Energy Storage Module" proposed in Chinese Patent Publication No. CN 215771427 U, it includes a box body, a battery module is fixedly connected inside the box body, a box cover assembly is fixedly connected to the top of the box body, and the two sides of the top of the box cover assembly are respectively fixedly connected with a positive terminal block and a negative terminal block, the positive terminal block is connected to the positive end of the battery module through a positive cable, and the negative terminal block is connected to the negative end of the battery module through a negative cable, and the box cover assembly includes an upper cover, a button is embedded on one side of the top of the upper cover, a communication interface is embedded on the other side of the top of the upper cover, and an indicator light is provided between the communication interface and the button, and a BMS component is fixedly connected to the bottom of the upper cover, and the button, communication interface and indicator light are electrically connected to the BMS component. The utility model has the characteristics of clarity and simplicity, simple installation, flexibility and variability, and the energy storage module is convenient for later expansion, which reduces costs.

[0007] However, the above device has the problem that the battery module needs to be replaced or repaired after long-term use to ensure that no accidents occur during the long-term use of the low-voltage battery energy storage module.
