Description

A kind of charger

Technical field

The utility model relates to a kind of charging device, is specially a kind ofly can effectively prolong the battery charger in useful life.

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 battery is put position, control forms etc.

Electric car charger is the device to the battery electric energy supplement, and the charging of electric motor car need be accomplished by charger, and traditional charger does not have regularly the break-make electric work can; In the process of charging, in the uncontrollable charging interval of charger, replenish how many electric weight; So just cause after battery is full of electricity, charger is still charging to battery, causes overcharging of battery easily; Not only waste electric energy; And make storage battery heating fill the drum distortion easily and cause damage, make the water electrolysis dehydration in the electrolyte simultaneously, reduce the useful life and the usefulness of battery.On the other hand; Because the influence of traditional concept; Think that life-span of storage battery receives the restriction of charging times, a lot of manufacturers and client reduce charging times as far as possible, fill once in about two days that have; Increase storage battery vulcanization and dead point so virtually and formed, shortened the useful life of storage battery greatly.Another reason of damaging battery is that a lot of users just charge as long as ride up to the place of charging in the needs charging immediately; Same like this have certain injury to storage battery, because least recently used storage battery all can produce heat, particularly summer; Go charging again, can make the battery secondary temperature elevation, the temperature of entire cell can get on very soon; So, this will cause electrolyte volatilization dehydration, even causes battery to fill drum.Facts have proved,, will cause the mortal injury that to repair battery as long as battery fills drum.So for battery of electric vehicle on the whole: " at first cooling, instant filling are not starved and are not supportted." this is the method for filling that the applicant sums up, and can let battery life prolong the secret place of several times.Fill the method detailed annotation: 1. rode charging on the same day same day; 2. ride back cooling charging in 1 hour at every turn; Charging interval not long, preferably what what fill with, when device to be charged became green light, floating charge half an hour was good (above method all can use the charging device of originally lengthening the life to realize full Based Intelligent Control) again; 4. charging for the first time, 8 winters 10 of summer (unit: hour, only for initial charge and park for a long time); 5. except that load and driving skills, battery life, also relevant with tire pressure, thus tire pressure must be sufficient (otherwise hinder tire easily or prick tire, hinder motor, Hall, battery, charger and controller).

The battery life and the method for using of electric motor car have direct relation.General 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 battery problem in useful life.Therefore advise user's charging in time of all try one's best every day: even if not long, electricly can use 2-3 days even fill once, but need all charge every day, can make battery be in saturation condition like this, the life-span can be prolonged greatly to the Capability Requirement that continues.

Most chargers are when charging, and the indicator light indication is full of after the electricity, and it possibly be 97%～99% that battery charges into electric weight, though 1%～3% the electric weight of only owing to charge almost can be ignored the influence of the ability of continuing.If untimely charging, battery discharge has just begun sulfidation later on, after the several hrs, 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.In addition, except charging every day, be also noted that, let the battery cooling just charge as soon as possible after use is over a little while, 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 was the best in 30 minutes to be full of the back prolongation generally.

In sum, because present existing charger, function ratio is more single; After battery is full of electricity, can not cut off the power supply automatically, but continue charging, often cause battery drum, disconnected lattice and phenomenon of losing water to occur filling; Shortened the useful life of battery, therefore needed further to improve.
