specific Embodiment 1

[0020] The standardized module adopts a 48V, 100AH ​​battery module and a lithium-ion battery. The module weighs 50kg. The module has a CAN communication port. The module shell adopts a standardized 3U (unit for communication backup power supply) size. The module has separate charging and discharging functions.

[0021] The energy storage battery pack consists of 1000 standardized modules with a capacity of 4.8MWH, which can provide 4.8MW of normal charging power ("peak clipping") and 4.8MW of normal discharging power ("valley filling"). The energy storage battery pack is distributed by the power management distribution system. In this power distribution basis, there are four groups of circuits that can be operated independently, each of which consists of 250 standardized modules. Through preset, the four circuits can be set as circuit A, circuit B, circuit C, and circuit D, and the preset circuit A is charged at 100%, circuit B is charged at 80%, and circuit C is charged at 5...

specific Embodiment 2

[0027] The following uses a specific embodiment to illustrate the application of the present invention to provide electricity provided by standardized energy storage battery packs in specific occasions.

[0028] The energy storage battery pack is the same as implementation 1. However, there are many villages next to the purchased enterprise, and a large part of the villagers go out to work. Normally, the power consumption provided by the transformer is surplus, but when people come back during the Spring Festival or harvest season, there will be a gap in power consumption, resulting in artificial time-sharing power outages. In order to solve the power shortage within a certain period of time, the surrounding villages negotiated a contract with the energy storage battery pack company to provide a power supply of 800KWH for two months in May-June and December-January each year, and the energy storage battery Group enterprises are responsible for power supply.

Abstract

The invention relates to an energy storage battery pack of a standardized energy storage module. The battery pack comprises an energy storage battery core, a battery management system, a battery communication port and a standardized shell. The standardized energy storage module comprises a fixed voltage and a fixed capacity and can be individually charged and discharged. The standardized energy storage battery pack possesses power station ''peak-load shifting'' of an existing energy storage battery pack, can provide an emergency power supply service for peripheral facilities requiring emergency power such as a communication base station, an emergency medical service, and an important data center and the like, provides power supply for a peripheral electric quantity required by person increase in a period of time, and can provide the power supply service for a national disaster and the like.

Description

technical field [0001] The invention relates to energy storage technology, in particular to an energy storage battery pack based on an energy storage module. Background technique [0002] Energy storage battery packs have been proven to have outstanding effects in terms of "shaving peaks and filling valleys" of the power grid and stabilizing the frequency regulation of the power grid. Moreover, it also plays an active role as an emergency / backup power supply for large electricity consumers. However, the initial purchase price of a 10MWH energy storage battery pack is about RMB 15 million (estimated according to the lithium-ion energy storage system). Such a high cost is a heavy burden for users, and it also limits the commercial promotion of energy storage battery packs. Moreover, the existing energy storage battery packs are fixed and indivisible systems, which limits the development and expansion of other commercial values ​​of the energy storage battery packs.
