Abstract

The invention discloses an electric vehicle sliding automatic charging circuit, which belongs to the device for charging the storage battery during the usage of electric vehicles. The invention provides the electric vehicle automatic charging circuit with improved circuit for executing charging in the sliding process of the electric vehicles on the basis of the invention 'electric vehicle sliding automatic charging circuit' applied by the inventor. When a single field effect transistor V1 is used for single-terminal output, the secondary electrode L1 of a high-frequency transformer T3 only outputs a half-wave rectified voltage. an S16, a D17, a C13 and an L2 are added, and the energy stored during the cut-off period T3 of the field-effect transistor V1 can be released by the D17 and the C13, so that the L2 can also output a half-wave rectified voltage in the reverse period of the V1. Accordingly, the entire device can output a full-wave rectified voltage and the rectification efficiency is improved by one time. Additionally, connected resistors and temperature-control switches can facilitate a more reliable operation of the device. The invention can prolong the running mileage of the electric vehicle, protect the controller and, more importantly, significantly prolong the service life of the storage battery.

Description

technical field [0001] The invention relates to a device for charging a storage battery during the use of an electric vehicle, in particular to an automatic charging circuit for electric vehicle sliding. Background technique [0002] With the progress of society and the development of science and technology, as well as the tension of global energy and people's continuous attention to environmental protection. The development of electric vehicles has become a demand of today's industrial production and people's lives. At present, many varieties of products such as electric vehicles and electric bicycles have come out. The power of the electric vehicle comes from the output of electric energy stored in the battery to start the mechanical movement. Therefore, the battery of the electric vehicle must maintain sufficient power to drive. Once the storage battery is out of electricity, then the electric vehicle just cannot travel, and the electric vehicle that cannot travel must c...
