Description

technical field [0001] The invention relates to a regenerative braking energy recovery system for a parallel hydraulic electric vehicle. Background technique [0002] At present, quite a lot of research has been done on the regenerative braking technology of electric vehicles abroad, and obvious progress has been made, and many products can be applied in real vehicles. In the regenerative braking system of gasoline-electric hybrid vehicles, batteries are often used abroad to recover braking energy. my country develops electric vehicles, electric vehicle regenerative braking systems, and proposes regenerative braking systems such as batteries, supercapacitors, flywheels, and hydraulic accumulators. Due to the existing domestic battery technology, it is difficult to use batteries or super capacitors as storage elements to recover braking energy. The series regenerative braking system CPS (Constant Pressure Source) is hydraulically driven by a constant pressure source. The fl...
