Abstract

The invention provides a portable intelligent charger of an electric car. The portable intelligent charger comprises a rechargeable battery, a weak current controlling and protecting module which is connected with the rechargeable battery, and a power factor correcting module which is connected with the weak current controlling and protecting module, wherein a resonant inverter rectifying module is connected between the rechargeable battery and the power factor correcting module; and a power device driving module connected with the weak current controlling and protecting module is arranged on the resonant inverter rectifying module. The portable intelligent charger can be used for overcoming the defects that the charger of the existing electric car is low in charging efficiency, low in reliability, high in power grid pollution and the like. The portable intelligent charger is high in charging efficiency as well as safe and stable to use.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a portable electric vehicle intelligent charger. Background technique [0002] The rapid increase in the demand for oil resources and the serious negative impact on the environment caused by the development of the automobile industry have increasingly attracted people's attention. Governments, academia and industry around the world are increasing investment in the development of electric vehicles to accelerate the development of electric vehicles. The pace of commercialization. One of the keys to the success or failure of an electric vehicle is the battery system, which is certainly related to the technical development of the battery itself. However, the charger as its energy supplement is also a crucial device. It must have a short charging time and have an impact on the service life of the battery. Therefore, it is very necessary to develop an electric vehicle battery fast charging ...
