The power storage technology of lithium ion battery is developing rapidly. Similar energy storage systems using different kinds of batteries have been widely used in the industry, such as lead acid batteries and sodium sulfur batteries, the introduction of lithium ion batteries for the new choice. Lithium battery energy storage application covers from small portable personal storage (such as mobile phone auxiliary power), to buffer is used to generated by wind turbines or solar panels of green energy mid size family energy storage, to large enterprises or public level energy storage on different occasions. All these applications provide a full range of battery products. Regardless of customer purchase is a single core or a full battery box system or subsystem, will be the whole process of the system integration of customers to provide design and technical support.
