Embodiment Construction

[0039] This embodiment provides a charging and repairing management method for lead-acid batteries of electric vehicles, such as figure 1 , 2 , 3, the charging management method of this embodiment adopts the multi-stage constant current pulse charging mode, which is divided into four stages: fast pulse charging repair stage, variable pulse charging stage, trickle charging stage and pulse maintenance stage. The control principles of different stages They are different, but the same is that they all use pulse switch control to realize the adjustment of parameters such as duty cycle and frequency, so as to complete the control tasks in different stages.

[0040] A. Fast pulse charging stage

[0041] This stage can be similar to the constant current and voltage limiting charging stage of a three-stage charger. When charging, the switching power supply is input with a constant current value of 0.1~0.3C. Different constant current values ​​​​are not achieved by adjusting the chargi...

Abstract

The invention relates to a charging and repairing management method and a charging and repairing device for a lead acid battery of an electric vehicle. The charging and repairing management method comprises a fast pulse charging stage, a variable pulse charging stage, a trickle charging stage and a pulse maintenance stage. The charging and repairing device realizes the charging and repairing management method by using the control of a single chip microcomputer. The invention discloses a pulse type charging repair control method, which adopts constant voltage and current limiting switching power supply technology, under the control of a single chip microcomputer, a charging repair device turns on and off the output current at a high speed, changes the direct current into a high-frequency charging pulse, and uses a digital control mode to precisely control the duty cycle of the charging current pulse.

Description

technical field [0001] The invention relates to the field of charge management of lead-acid batteries, in particular to a charging and repairing management method and a charging and repairing device for lead-acid batteries of electric vehicles. Background technique [0002] In recent years, with the development of my country's economy, the electric vehicle industry has been widely popularized. So far, the market size of my country's electric vehicle industry has ranked first in the world. With the continuous economic growth and the improvement of the income level of urban and rural residents, due to the The convenience and environmental protection of bicycles make the electric bicycle market show a momentum of continuous growth and stable development. At the same time, consumers have higher and higher requirements for product quality. [0003] At present, lead-acid batteries are still used as the main power storage device for electric vehicles due to their advantages of low...
