Technical Field

[0001] This invention relates to the field of vehicle power supply technology, specifically to a vehicle power supply cold start power consumption compensation device and operating method. Background Technology

[0002] A car battery is a device used in automobiles to convert chemical energy into electrical energy. It is a DC power source, providing a strong starting current to the starter motor when the engine is started; assisting the generator in supplying power to electrical equipment when the alternator is overloaded; supplying power to electrical equipment when the engine is idling; and acting as a large-capacity capacitor to protect the car's electrical appliances. When the alternator terminal voltage is higher than the electromotive force of the lead-acid battery, some electrical energy is converted into chemical energy for storage, i.e., charging. The battery is an essential part of a car and can be divided into traditional lead-acid batteries and maintenance-free batteries. Onboard power generally refers to a power inverter, which converts DC 12V direct current into AC 220V alternating current, the same as mains power, for use by general electrical appliances. It is a convenient power converter. A cold start is starting the car when the engine coolant temperature is low, usually caused by the car not being started for a long time.

[0003] Existing vehicles suffer from insufficient battery power during cold starts due to excessive contact resistance in the battery connection wires, preventing the alternator from supplying power in a timely manner. This affects the normal operation of the vehicle's electrical equipment.

When the power consumption of the vehicle's electrical equipment is insufficient during a cold start, the vehicle's power inverter converts the DC power generated by the photovoltaic solar panels into AC power and supplies it to the vehicle's electrical equipment to make up for the insufficient power consumption. This overcomes the problem in existing vehicles where the alternator cannot supply power in time due to excessive contact resistance of the battery connection wires during a cold start, resulting in insufficient battery power and affecting the normal use of the vehicle's electrical equipment.

[0023] 2. When the car is not in use, the photovoltaic controller charges the internal storage of the vehicle battery with electrical energy. When the car is cold started, the ignition switch is turned on and the integrated alternator generates AC power. The AC power generated by the integrated alternator is used by the vehicle's electrical equipment, thus achieving the purpose of energy saving and replenishing power consumption.

[0024] 3. The vehicle remote control module is operated remotely via a mobile terminal. Then, the vehicle remote control module triggers the body controller to control the cover controller.
