DC-DC12V25A adaptor having electric door lock function special for electric vehicle

Abstract

The invention relates to a DC-DC12V25A adaptor having an electric door lock function special for an electric vehicle. The adaptor comprises a main circuit and a control circuit, wherein the two circuits employ independent circuit boards to achieve flexible plug of the main circuit and the control circuit, replacement and troubleshooting are facilitated when a fault occurs in one of the circuit boards, the whole circuit board is not needed to be replaced, the adaptor is convenient to maintain and install, materials are saved, and the production efficiency is improved; the electric door lock function, energy storage and output over-voltage protection can be achieved by the main circuit, and the control circuit has an effect of voltage stabilization on the circuit; the control circuit comprises a control chip, a voltage stabilization circuit, an oscillation circuit and a pulse output circuit; a voltage, such as 48V, 60V, 64V and 72V, used by a storage battery of the electric vehicle is converted to 12V, and a rated working voltage is provided for a 12V low-voltage power utilization device such as a lighting lamp, an instrument, a horn, a window wiper, a light indicator, a fan, a radioand a backup camera.

Description

technical field [0001] The invention relates to a converter capable of converting the DC high voltage of an electric vehicle battery pack into a DC 12V low voltage, which is used to provide rated working voltage for the lighting system, signal indicating system, and various auxiliary electrical appliances of the whole vehicle. Circuit technology field. Specifically, it is a special DC-DC12V25A converter for electric vehicles with electric door lock function. Background technique [0002] At present, the DC / DC power converters of electric vehicles on the market do not have the electric door lock control function, which makes the converters work for a long time, reduces the service life of the converters, consumes the electric energy of the battery, and also brings hidden dangers to the safety of the whole vehicle. . Moreover, there are technical problems such as insufficient output power, poor voltage stabilization effect, poor load capacity, easy damage, and easy to burn l...
