Description

technical field [0001] The invention belongs to the field of power supply equipment, and in particular relates to a multifunctional mobile energy storage vehicle with a common bus and a control strategy. Background technique [0002] The current electrochemical energy storage is limited by the high cost of energy storage batteries, which severely limits the promotion and application of electrochemical energy storage. The mobile emergency power supply using batteries as energy storage medium is also difficult to be recognized by users because the cost is much higher than that of diesel power generation. With the popularity of electric vehicles, road emergency rescue vehicles for electric vehicles have begun to be favored by the industry. Compared with diesel power generation, electrochemical energy storage has the characteristics of green, pollution-free and low noise. It can realize AC or DC output by matching with corresponding AC and DC inverters. [0003] The Chinese pa...
