Abstract

An electric vehicle inverse charging converter includes a back-emf pre-collection module 1, a constant current boost module 2, a self-power module 3, a switching power supply integrated controller 4 and a discrimination module 5. The converter separates and extracts the counter-electromotive force lower than the accumulator electric voltage from the circuit, and then charges the accumulator in a constant-current modus, thereby saving about 30% energy consumption of the electric car, extending battery service life and increasing running mileage.

Description

technical field [0001] The invention relates to an energy-saving device for an electric vehicle, in particular to a reverse charging device for an electric vehicle. Background technique [0002] When the electric vehicle has no shifting device and is easy to start, there are many ups and downs in cities, especially mountainous cities, so coasting or braking is frequent. When the electric vehicle is gliding or braking, the motor windings will generate back electromotive force due to cutting the magnetic force lines, and the electric vehicle reverse charging converter will collect the generated back electromotive force and store it in the battery. The current electric vehicle reverse charging circuit such as Figure 10 shown. The disadvantages of this technology are: (1) Since the speed of the electric vehicle is generally lower than 50Km / h, the back electromotive force generated is lower than the battery voltage (generally the electric vehicle battery is 36V or 48V), so the ...
