Description

[0001] Technical field [0002] The invention relates to a vehicle power supply delay device. Background technique [0003] Existing vehicles, such as passenger cars, generally contain engine electronic control devices, also known as engine controllers (ECUs), and the power supply of the controllers (ECUs) is provided by a power converter system. The input end of the power converter system is connected with the vehicle battery, and its output end is connected with the engine controller (ECU). The power converter system contains a voltage stabilizing integrated circuit. When the circuit supplies power to the system, the power converter system starts to work. After the vehicle is parked, it takes about 20 seconds for the electronic module data storage of the engine controller (ECU), and the vehicle battery of the existing vehicle has been supplying power to the engine controller (ECU) through the power converter system. In fact, the electronic module data storage of the engine...
