Description
Affiliated technical field
The present invention relates to a kind of electric bicycle charging method and equipment, charging method and intelligent charger when definite a kind of electric bicycle of saying so is controlled automatically.
Background technology
Electric bicycle is made up of car body, electric driver (motor), rechargeable battery, charger and control system five major parts.Different types of car, it is different that its control system is put position, control forms etc.
Electric car charger is the device to the battery electric energy supplement, and traditional charger does not have regularly break-make electric work ability, and the charging of electric motor car need be accomplished by charger; In the process of charging, the uncontrollable charging of charger how long, so just causes behind the battery full charge; Charger is still charging to battery, causes overcharging of electric motor car easily, not only wastes electric energy; Storage battery is carried out overtime charging make the battery deformed damaged, thus the useful life of reducing battery.
Battery of electric vehicle is a dynamic life, the strict charger that does not have enough to guarantee the battery charge quality in the market of saying.But the higher is the price, the better is the quality of the merchandise, and good charger can have good charging and protection effect to battery really.Group method is: duty is filled shallow putting, and does not starve and does not support.Promptly each the use tried not once to use under-voltage, and it is hot that each charging also tries not to be charged to heating, and be more can not the time of a specified duration excessively.At present charger generally all is according to being full of (refer to ridden far away, battery discharge is near under-voltage situation) design in 8～10 hours, and each Battery Plant instructs charging according to the method.But have been found that: charging (particularly summer) at ordinary times be as long as the time length of filling will make battery heating distortion, particularly also do not have the battery that can let of real meaning be full of with regard to automatic stop function in the market.
The battery life of electric motor car and charging method have direct relation.Experienced user knows that the expense of changing battery is to use the maximum expenditure of electric motor car, so all be concerned about very much the problem in the useful life of battery.Your charging in time of all try one's best every day of this method suggestion: even if your Capability Requirement that continues is not long, fills once electricity and can use 2 to 3 days, still still want all charge every day, can make battery be in shallow recurrent state like this, the life-span of battery can prolong.The memory benefit of lead acid accumulator is so not strong.It is bigger to the effect on service life of battery often to have put electricity.Most chargers are after the indication of indicator light change lamp is full of electricity, and it possibly be 97%～99% that battery charges into electric weight.1%～3% electric weight almost can be ignored the influence of the ability of continuing though only owe to charge.If untimely charging, battery discharge has just begun sulfidation later on, beginning in 12 hours, tangible sulfuration just occurred.
In time charging can be removed sulfuration, prevents to vulcanize the crystallization accumulation and progressively forms thick crystallization, and general charger is helpless to these thick crystallizations, can progressively form the decline of battery capacity, has shortened the useful life of battery.So, except charging every day, be also noted that, after being over, use let battery cool off a little while just charging as early as possible a little, and make battery be in full state as far as possible.
Charging interval must guard against long: many electric motor car users think that long more battery electric quantity of charging interval is sufficient more, and this is very wrong.Charging interval 10-20 minute was the best (conventional method is that suggestion is full of back prolongation 1-2 hour, and is unassisted here) to be full of the back prolongation generally.Overcharge for a long time and can make battery distortion, dehydration etc., thereby directly shorten the life-span of battery.
The most handy smart jack of electric motor car charging: numerous electric motor car users charging of coming home from work, to cut off the electricity supply when going to work in second day, big in fact multi-charger can not absolutely guarantee when battery is full of, to cut off the power supply automatically.Best bet is to choose smart jack, sets the time during charging, so just can solve the problem of feeling at ease to have a rest evening.
