Battery energy storage probably means placing the batteries inside the energy storage container, and then there are BMS battery management systems, EMS energy management systems, etc. arranged inside. BMS is now widely used in electric vehicles. EMS mainly manages a large number of energy storage batteries and ensures a stable and reliable connection to the power grid.


The electrochemical energy storage system uses electrochemical batteries as energy storage carriers and stores and releases cyclic electrical energy through energy storage converters. The energy storage system consists of energy storage batteries, electrical components, PCS bidirectional energy storage converters, EMS It is composed of energy management system and BMS battery management system and other components.


Energy storage batteries generally adopt a modular energy storage method. The cells are composed of modules. The modules are placed in the electrical box, and the electrical box forms the battery cabinet, which in turn forms the energy storage unit.


PCS can realize two-way energy transfer between the DC battery of the battery energy storage system and the AC power grid, and realize the charge and discharge management of the battery system through control strategies. EMS mainly collects energy storage power station information and accepts power grid dispatching instructions to achieve peak regulation, frequency regulation, and smoothing fluctuations. The BMS monitors the battery status and realizes the monitoring of the battery status.


Energy storage wire harness is a common connection wire in battery energy storage system. It mainly plays an important role in signal, data and power transmission. Before wireless transmission technology is mature enough, energy storage wire harness plays an important role in the field of energy storage.


In addition to being used in photovoltaic energy storage, communication base station energy storage, mobile energy storage, shared energy storage and other energy storage fields, energy storage wire harnesses also serve as connecting lines between new energy electric vehicles, electric vehicle motors, batteries, air conditioners and other components. .


In the field of new energy vehicle research, truly outstanding car companies and suppliers will continue to grow, and star companies in the industry chain will emerge one after another. Technological progress is like a gravitational star, where talents and funds will gather. Once competitive advantages begin to form, new energy vehicles are likely to become the pillar industry with the greatest global influence in China's entire economic structure.
