Automatic time-control charging method and intelligent charging device of electric bicycle

Abstract

The invention relates to a charging method and equipment of an electric bicycle, in particular to an automatic time-control charging method and an intelligent charging device of the electric bicycle. The automatic time-control charging method comprises the following steps of: reading riding current and riding time from an input / output bus of an electric bicycle battery through utilizing a single chip system and performing the statistic, meanwhile, obtaining a temperature of the current environment and calculating the change of a battery capacity, and finally, calculating electric quantity needing to be supplemented; and through comprehensively considering factors including air temperature, energy conversion efficiency and the like, calculating the charging time by using the following formula: T=[1+(25-X)%]Q / (99%I), namely obtaining the current charging time. The intelligent charging device comprises a charger with a time-control relay; the electric bicycle is internally provided with the single chip system which is used for calculating the charging time of the electric bicycle; a signal input end of the single chip system is respectively connected with the input / output bus of the electric bicycle battery and a temperature probe through data lines; a signal output end of the single chip system is connected with the input / output bus of the electric bicycle battery and the temperature probe through the data lines of the charger; and the switching-on or switching-off of a working circuit of the charger is controlled through using the time-control relay.

Description

Technical field [0001] The invention relates to a charging method and equipment for an electric bicycle, in particular to a charging method and an intelligent charging device for automatic control of an electric bicycle. Background technique [0002] An electric bicycle consists of five parts: a car body, an electric drive (motor), a rechargeable battery, a charger and a control system. Different types of vehicles have different control system placement locations and control forms. [0003] The electric vehicle charger is a device that supplements the battery with electric energy. The traditional charger does not have the function of regularly turning on and off the power. The charging of the electric vehicle needs to be completed with the help of the charger. During the charging process, the charger cannot control the charging time. In this way, after the battery is fully charged, the charger is still charging the battery, which will easily cause overcharging of the electr...

Problems solved by technology

[0009] However, there is a problem in existing smart sockets including timing chargers: how to accurately determine the charging time, especially most electric vehicles do not have odometers, and users cannot accurately know how many miles they have traveled and how long they should be charged. It can only roughly estimate the charging time, and the accuracy is poor. Especially, most people find it troublesome to estimate the charging time and use the timer. Therefore, the existing smart sockets, including timers, have great limitations in improving battery life.
