Problems solved by technology

[0002] The existing group vehicle charging system has a fixed output power and a single charging mode, which is far from meeting the charging needs of vehicles with different power levels and cannot provide an optimal charging method
Moreover, the system is complex and the power is small, so it is difficult to realize simple batch production
The cabinet is single, and it is difficult to realize flexible combination and parallel expansion between cabinets
The existing expansion method mainly adopts the matrix expansion method, the cost is too high, the control system is complicated, and it cannot be effectively applied to the market

Abstract

The invention discloses a charging method and system as well as a charging controller. InAccording to the system, an annular bus is adopted to connect the output ends of multiple power units in seriesand is provided with switch units for isolating adjacent power units, so that the whole architecture is simple. When an amount of charging guns needing to be charged is changed, on the one hand, thepower units, corresponding to the charged charging guns, are maintained in a power-on state to ensure continuous charging of a vehicle; and on the other hand, the states of other power units and the states of various switch units on the annular bus are regulated, a power of multiple power units is shared to all the charging guns needing to be charged after being integrated, so that the powers of multiple power units are fully utilized, the charging efficiency is improved, various power units in the system are effectively and flexibly distributed to various charging guns respectively, and the problems of too many contactors or relays, high cost, complex software control and the like in the prior art are solved.
