Nickel-hydrogen battery charging method

Abstract

The invention relates to a nickel-hydrogen battery charging method applicable to a car-mounted electronic device or a car-mounted electronic system. The method comprises that the car engine state and the nickel-hydrogen battery electric quantity are read through a processor, a car storage battery is controlled to provide different charging manners for the nickel-hydrogen battery, wherein the charging manners comprises a routine charging manner and a trickle charging manner. The method is capable of guaranteeing that the car storage battery does not feed, also is capable of prolonging the service life of the nickel-hydrogen battery to a great degree, and satisfies the low-power requirement of the car-mounted electronic device or the car-mounted electronic system at the same time.

Description

technical field [0001] The invention relates to a charging method of a rechargeable battery, in particular to a charging method of a nickel-metal hydride battery. Background technique [0002] With the development of the automobile industry, more and more electronic devices are loaded on the automobile. The on-board electronic device needs to be equipped with a rechargeable battery to ensure that the on-board electronic device can keep working normally when the car's power supply is abnormal or out of power, and the on-board electronic device has higher requirements on the rechargeable battery. At present, most of the rechargeable batteries equipped with on-board electronic devices are Ni-MH batteries, but the commonly used charging methods for Ni-MH batteries are long-term regular charging and trickle charging according to the battery power, regardless of the current engine status and after the vehicle is turned off. The requirement of low power consumption leads to advers...

At present, most of the rechargeable batteries equipped with on-board electronic devices are Ni-MH batteries, but the commonly used charging methods for Ni-MH batteries are long-term regular charging and trickle charging according to the battery power, regardless of the current engine status and after the vehicle is turned off. The requirement of low power consumption leads to adverse consequences that affect the body battery and even cause the body battery to feed power, and at the same time cannot guarantee the life of the Ni-MH battery
