Abstract

The invention discloses a voltage holding circuit and an applicable vehicle device thereof. The voltage holding circuit is connected with a starting element and a traffic control unit; the starting element outputs a starting signal; the voltage holding circuit comprises a first switch unit, which receives an input power source and includes a first output end, a voltage maintenance unit, which is connected with the first output end and the starting element to receive the starting signal and output maintenance voltage, and a voltage adjusting unit, which is connected with the traffic control unit and the first switch unit and has an end point. The end point has adjusting voltage, wherein the traffic control unit controls and adjusts a voltage value of the voltage; the first switch unit operates according to the voltage difference between the maintenance voltage and the adjusting voltage; the first output end outputs the input power source and the voltage maintenance unit receives the input power source so that the voltage maintenance unit lastingly outputs the maintenance voltage when the first switch unit is conducted. The invention can avoid the loss of micro-power and reach the effect of totally saving electricity.

Description

technical field [0001] The invention relates to a voltage holding circuit, in particular to a voltage holding circuit and a vehicle device to which it is applied. Background technique [0002] In recent years, due to rising gasoline costs, long commuting time, traffic congestion causing a large amount of exhaust gas emissions, and the greenhouse effect have become increasingly serious, electric vehicles that are purely powered by electricity have been designed to replace traditional fuel-engine vehicles. However, electric vehicles must Installing a large number of heavy battery devices in the car has problems such as inconvenient charging, long charging time, and poor battery life. Therefore, in order to save car oil and avoid environmental pollution, it must be able to provide enough horsepower, oil The design concept of hybrid electric vehicle (also known as environmental protection and energy-saving vehicle) is born accordingly. [0003] A gasoline-electric hybrid vehicl...
