Problems solved by technology

At the same time, it adopts the design of DO anti-reverse connection interface, which can automatically identify the reverse connection of the battery to avoid wrong operation. However, at present, the identifiable voltage for reverse connection safety detection is greater than 2V, and the reverse connection detection cannot be performed in the forced output startup mode.
As a result, there is a certain security risk

Description

Low voltage identification pre-charged smart car emergency start circuit technical field The present invention relates to the technical field of intelligent automobile emergency start circuit, be specifically related to a kind of low-voltage identification pre-charged intelligent Can car emergency start circuit. Background technique [0002] At present, the car starts relying on the battery to provide an instantaneous large current, and the car is started through the starter. Start the battery Said battery, scientific name lead-acid battery. After decades of technological innovation, the current batteries are basically maintenance-free and do not require To add water or dilute sulfuric acid. All batteries, even when not in use, self-discharge, which means that if the battery is not in use, With the extension of time, the capacity of the internal storage will be gradually reduced or even exhausted. [0003] During the discharge process of the battery, there is polari...
