Abstract

The invention discloses an input and output circuit for a car jump starter. The input and output circuit comprises a charging input circuit and a power output circuit; the charging input circuit includes four input interfaces, namely, a car storage battery power taking interface, a dry cell charging interface, a USB charging interface and a car cigar lighter interface; and the power output circuit includes a relay. The input and output circuit for the car jump starter includes different types of power interfaces, and is especially suitable for charging mobile power supplies in occasions without AC power supply.

Description

technical field [0001] The invention particularly relates to an input and output circuit used for starting a power supply of an automobile. Background technique [0002] The mobile power supply is widely used. The existing mobile power supply is generally connected to the AC power supply through the power adapter to obtain electric energy. However, charging becomes very difficult when the AC power supply is inconvenient. [0003] In addition, the car starting power supply needs to output a large starting current to the car, and the current value reaches several hundred amperes, so its output control circuit needs to be specially designed. [0004] Therefore, it is necessary to design an input and output circuit for the car starting power supply. Contents of the invention [0005] The technical problem to be solved by the present invention is to provide an input and output circuit for automobile starting power supply. The input and output circuit for automobile starting po...
