Abstract

The invention discloses an intelligent earth wire for connecting an automobile emergency startup power supply with an automobile storage battery. According to the invention, an MCU is adopted as a control chip and combined with a power supply circuit, a temperature detection circuit, a voltage detection circuit, a working state prompting circuit, a load access detection circuit, a load connectionstate identification circuit, a connection control circuit and other peripheral circuits. In this way, an automobile storage battery externally connected with the earth wire can be detected. By meansof the MCU, the connection state of the automobile storage battery can be judged. Meanwhile, when the automobile storage battery is in a positive connection state, the electric connection between a first negative electrode connecting end and a second negative electrode connecting end is connected through a connection control circuit control switch. The automobile emergency startup power supply andthe automobile storage battery are connected in parallel. In this way, the formation of a short circuit at the two ends of the earth wire is avoided. Meanwhile, the occurrence of a safety accident caused by the reverse connection of the automobile storage battery is avoided, so that the product is safer and more reliable.

Description

technical field [0001] The invention relates to automobile electronic technology, in particular to an intelligent fire wire for connecting an automobile emergency starting power supply and an automobile storage battery. Background technique [0002] With the rapid reduction of automobile manufacturing costs, automobiles have gradually become people's daily means of transportation. However, most car batteries use lead-acid batteries, and the charging and discharging performance of lead-acid batteries will be greatly reduced under low temperature conditions, so many cars cannot be started in cold winter. In order to solve this problem, car emergency The starter power came into being. Automobile emergency starting power usually uses high-rate lithium batteries as energy storage batteries, which will not affect the corresponding charge and discharge performance due to low temperature, which well makes up for the shortage of lead-acid batteries. With the wide application of car...
