Abstract

The main structure consists of the volt change conversion unit, the rectification unit, the power conversion output unit, the start control unit and the charging control unit. This charging device (CD) has advantage: during car start, controlling CD to charge the car battery; ensuring that the battery has enough energy to offer the start current; helping the car to start; CD can help car start when the battery energy is insufficient and the city power is not available; after charging, CD will stop automatically. Features are: small volume, lightweight, low noise and low cost. It has a protection means specially designed for CD to prevent CD from damage caused by short circuit or opposite connection so as to extend service life.

Description

technical field [0001] The invention relates to an auxiliary device for an automobile, in particular to a charging device which can help the automobile to start. Background technique [0002] The battery in the car is one of the essential power devices in the process of starting and running the car. The traditional car battery charging device is generally a lead-acid battery charging device, and its circuit structure is relatively complicated. And most of the car battery charging devices in the prior art use laminated transformers, namely EI transformers, which not only have large volume and weight, are inconvenient to carry, but also have low power, high vibration and noise, and high cost. [0003] When the car starts, it needs a large current, especially in a cold environment, and the battery needs to have a high energy to start. Therefore, when the power of the battery is insufficient and cannot provide the large current required for starting, the car is difficult or imp...
