A high power anti-polarization electric vehicle charger comprises a rectification, filtering and voltage stabilizing control circuit, a photoelectricity coupling unit and a pulse formation control unit, a pulse formation control circuit power supply unit connected with the pulse formation control unit and providing power supply, and an inverter unit which are connected in sequence, wherein the inverter unit is respectively connected with the rectification, filtering and voltage stabilizing control circuit, the photoelectricity coupling unit and a high frequency transformer unit; and the output of the high frequency transformer unit and the output of the pulse formation control circuit power supply unit are respectively connected with a non-balance form and sampling feedback unit. In the process of the depolarization of a VRLA storage battery of an electric vehicle, the charger provided by the invention remarkably reduces the inner pressure, the temperature and the inner resistance of the storage battery (no deformation), prolongs the service life of the storage battery, and stabilizes beta-PbO2 proportion and other indexes. The charger has an output voltage range 36V-48V so as to be selectively used, and is universally applicable to electric tricycles and electric bicycles.
Description
technical field [0001] The invention relates to an electric vehicle charger. In particular, it relates to a high-power anti-polarization electric vehicle charger. Background technique [0002] As electric vehicles enter thousands of households, the requirements for electric vehicle chargers are getting higher and higher, especially the charger circuit design is reasonable, easy to use, short charging time, long use time, etc. However, the existing electric vehicle chargers generally have some unreasonable circuit structures, such as the existing commercially available small current chargers that cannot be depolarized, and the constant voltage or constant current charging time is as long as 10-20 The disadvantages of hours, and there is also the problem of service life. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a high-power anti-polarization electric vehicle charger which reduces the internal pressure, tem...
