Problems solved by technology
[0005] Traditional charging technology is limited by factors such as single energy source, non-movable equipment, and poor battery energy storage effect, which has brought about difficulties for operators to install new charging equipment, large investment in construction and maintenance, poor charging experience for electric vehicle users, and high time costs. , the power supply bureau is also facing huge challenges in the time of peak power consumption and off-peak idle time, as well as in dense residential areas, highway rest areas, and temporary parking areas for large-scale events.
[0006] In summary, traditional electric vehicle charging equipment can no longer meet market demands such as rapid erection, decentralized deployment, rapid power replenishment, and optimal utilization of energy.

The invention provides a distributed mobile digital energy storage system for rapid charging of an electric vehicle, and the system comprises a low-power charging unit which serves as an energy supplementing device; a digital battery energy storage unit as an energy storage unit; the high-power direct-current discharge unit is used as an energy output device; and the system energy management and control unit is used as a control center of the mobile digital energy storage system. By adopting the efficient digital battery energy storage system and the internet management and control platform, the digital battery energy storage system is subjected to digital, virtualization and internet accurate management and control, the design function of slow charging and quick discharging is achieved, cost increase caused by transformation of an existing power grid is avoided, and efficient management and operation of distributed energy storage assets are achieved. And meanwhile, a mobile charging function is provided for the electric vehicle, so that the electric vehicle can be quickly charged nearby, the mileage anxiety of an electric vehicle user is reduced, and the defect of the last kilometer of a current charging network is overcome.
Description
technical field [0001] The invention relates to the technical field related to electric vehicle charging, in particular to a distributed mobile digital energy storage system for fast charging of electric vehicles. Background technique [0002] With the rapid growth of the number of electric vehicles in my country, electric vehicle charging guarantee service has become the focus of the industry. The existing charging stations for electric vehicles include AC slow charging stations, DC fast charging stations, etc. Among them, AC slow charging technology is widely used in large charging stations and portable charging equipment, but because of this form of charging The charging power of the charging station is small, and electric vehicles need to be parked in fixed parking spaces for a long time, which greatly limits the "dynamic properties" of electric vehicles. [0003] Although the DC fast charging station has charging power several times that of the AC charging station, the...
