High-power high-reliability voltage retainer used for automobile starting and stopping system

Abstract

The invention provides a high-power high-reliability voltage retainer used for an automobile starting and stopping system. The high-power high-reliability voltage retainer is higher in power and reliability and smaller in size and ripple. The high-power high-reliability voltage retainer comprises a through circuit module (1), a booster circuit module (2), a reversed polarity circuit module (3), a CAN transceiver (4), a CPU (5), a DSP (digital signal processor) (6) and a battery. A battery input port and a battery output port are formed in the through circuit module (1), a battery input port and a battery output port are formed in the booster circuit module (2), and the reversed polarity circuit module (3) is electrically connected with the booster circuit module (2); the CAN transceiver (4), the CPU (5) and the DSP (6) are sequentially and electrically connected; the CPU (5) is electrically connected with the through circuit module (1), and the DSP (6) is electrically connected with the through circuit module (1); the DSP (6) is electrically connected with the booster circuit module (2).

Description

Technical field [0001] The invention relates to an automobile accessory, in particular to a high-power and high-reliability voltage keeper used in an automobile start-stop system. Background technique [0002] Currently, among the automotive hybrid technology, hybrid vehicles with start-stop control (Start_Stop_System) have begun to spread. When this type of car stops at a red light, the gasoline engine is turned off, and the battery provides short-term power; and when the red light turns to a green light, stepping on the engine accelerator will restart the gasoline engine and switch back to the gasoline engine to provide power and Charge the battery. Obviously, this kind of technology is more energy-efficient than cars waiting all the time; as hybrid vehicles with start-stop control continue to be put on the market, it will definitely contribute to the energy-saving and emission reduction of cars and the implementation of higher vehicle emission regulations. The driving effect...

AI Technical Summary

Problems solved by technology

This physical phenomenon, in a hybrid vehicle with start-stop control, if not controlled, will bring serious impact and interference to the electrical system of the vehicle, making the electrical work of the vehicle disordered and causing great confusion to the driver

[0004] At present, most of the voltage holders on the market are low-power and low-reliability components (such as 200W or 400W), and some hybrid vehicles with low power requirements can meet the requirements

For other cars that require high-power and high-reliability voltage retainers, these components cannot meet their working requirements.
