Abstract

The invention discloses an automobile engine start control system, which comprises a super capacitor energy storage component, a storage battery, a relay and a body control module, wherein an anode of the super capacitor energy storage component and an anode of the storage battery are respectively connected with the relay, a cathode of the super capacitor energy storage component is connected with a cathode of the storage battery, and the relay is further connected with the body control module. The automobile engine start control system can avoid potential safety hazard caused by connection of a capacitive filter with the storage battery, and can play a buffer role in high current impact when an engine is started.

Description

technical field [0001] The invention relates to an automobile engine starting control system. Background technique [0002] The current automobile engine start control system is an automobile battery and a capacitor filter. This capacitor filter is directly connected to the battery to stabilize the voltage to a certain extent. Since the capacitor filter is always connected to the battery and cannot be disconnected, there are hidden dangers in safety. As the battery self-discharges, the electrical energy stored in the capacitor gradually decreases. The structure of this capacitor filter mostly uses multiple 25V, 2200UF capacitors connected in parallel, and there is often a lag in the storage and response speed of electric energy. Moreover, the cut-in of the capacitor is not controlled, and it does not have a buffering effect on the high current impact of starting the engine. Contents of the invention [0003] Purpose of the invention: In view of the problems and deficien...
