An extended-range generator controller and its control method

Abstract

The invention discloses a range extending type power generator controller and a control method thereof. The range extending type power generator controller comprises a power generator control switch set, a charging control switch set, an interlocking module, a two-way AC / DC power device and a control system module. The two-way AC / DC power device is connected with the output end of an automobile power generator through the power generator control switch set and connected with an alternating current charging connection socket through the charging control switch set. Both the power generator control switch set and the charging control switch set are connected with the interlocking module. Both the interlocking module and the two-way AC / DC power device are connected with the control system module. The output end of the two-way AC / DC power device is connected to an automobile power battery set through a high-voltage distribution box. By the adoption of the scheme, two controllers are combined into one controller, the arrangement space of power system components is reduced, high-voltage and low-voltage wiring harnesses are simplified, the weight of a power system is reduced, and the cost of the power system is reduced. The scheme is suitable for all electric vehicles with range extending type power generators.

Description

technical field [0001] The invention relates to the field of charging and discharging control of a hybrid electric vehicle, in particular to an extended-range generator controller integrated with the function of a vehicle-mounted charger and a control method thereof. Background technique [0002] At present, there are two commonly used charging methods for electric vehicles: one is to build a professional charging station to realize DC high-power fast charging, but the investment is huge and it is difficult to recover the cost, and it is difficult to carry out commercial promotion; the other is a low-power car charger. , although the charging is convenient, the AC charging power is small and the charging time is too long, which cannot meet the needs of electric vehicles. [0003] The power battery capacity of the extended-range electric vehicle is much smaller than that of the pure electric vehicle power battery, so there is room for the on-board low-power charger. At presen...

Problems solved by technology

[0006] The present invention mainly solves the technical problems existing in the prior art that the separate control of the on-board charger and the generator leads to large space occupation, complicated wiring harness, increased weight, etc., and provides a device that reduces the layout space of power system components and simplifies the high and low voltage. Wiring harness, a range-extending generator controller that reduces the weight of the power system and reduces the cost of the power system, and provides a control method for the range-extending generator controller
