Energy-saving power supply device for automobile

Abstract

The invention provides an energy-saving power supply device for an automobile. The energy-saving power supply device comprises an automotive generator, a generator controller and a main battery, wherein the generator controller detects the voltage level state of the main battery, automatically controls the automotive generator to charge the main battery when the voltage of the main battery is in a low state, and controls the automotive generator to unload when the power of the main battery is full, so that fuel is saved, the overcharge of the main battery is avoided, and the life of the battery is prolonged. The energy-saving power supply device is additionally provided with a standby power supply, and then, an auxiliary battery can be used for supplying power to start up the automobile when the power of the main battery is used up because an automobile user forgets to turn off headlights or overuses electrical equipment on the automobile without starting up an engine. Moreover, the energy-saving power supply device is provided with a solar charging assembly which is connected with the main battery and is used for charging the main battery, so that the main battery can be kept in a full-power state; and the power supplying time of the automotive generator is reduced by using the solar energy for power supply, so that the unload time of the automotive generator can be longer, the thrust to the generator caused by the engine is reduced, and the fuel consumption is saved.

Description

technical field [0001] The invention relates to an automobile power supply device, in particular to an energy-saving automobile power supply device, which can save fuel consumption by generators. Background technique [0002] Today's international crude oil prices are rising steadily, and oil prices have become a burden for drivers. Not only that, the global environmental pollution caused by massive fuel consumption has gradually surfaced, and has gradually attracted the attention of the public. Therefore, automobile-related industries must study vehicles and The harmony of the environment reduces fuel consumption. However, in order to achieve good sales, the current automobile industry is constantly expanding the electrical equipment in the car, such as digital TV, DVD player, LCD display, satellite navigation, and DC 12V to AC110V power conversion. A large amount of energy stored in the battery is consumed by the device, fog lights, etc., and the large amount of electricit...

In this way, when the vehicle is moving, the storage battery 81 can be continuously charged to maintain a full state of power; however, from the above-mentioned design of the current vehicle power supply device, it can be seen that after the storage battery 81 is fully charged, as long as the engine continues to run, The car generator 80 will overcharge the storage battery 81, which not only causes the engine to cause more fuel waste for driving the car generator, but also shortens the life of the battery, which is not ideal

[0004] Moreover, because m...
