Description
Technical field
The present invention relates to a kind of charger that shows the rechargeable battery charge volume that possesses, the multistage electric weight ratio that particularly has additional on charger shows the actual display unit of finishing the charge capacity value of rechargeable battery, when allowing the user take rechargeable battery, can carry out the action of interpretation and demonstration to the actual charge capacity of rechargeable battery.
Background technology
Rechargeable battery, provide people on the electrification product, not worry the power breakdown problem, its facility is carried and reusability, also improve operational facility of people and environmental protection child care function, because the rechargeable battery capacity significantly increases and the increasing of rechargeable battery material, the rechargeable battery application surface is increasingly extensive, on existing operating surface, no longer be confined to as small household appliances such as sound equipments, but rechargeable battery applied to large-scale means of transportations such as electric motor car, therefore, how rechargeable battery is carried out the validity charging and become a suitable important technology.
See also Republic of China's patent gazette No. 507412 " rechargeable battery charging device; rechargeable battery set charging method; and rechargeable battery set ", the rechargeable battery charging device that it disclosed, in order to the rechargeable battery set with rechargeable battery is charged, rechargeable battery set can store the information of the information of maximum charging current of expression rechargeable battery and maximum charging voltage and be connected this information, and has a memory mechanism that is used for storing the digital information of maximum charging voltage; Perhaps as No. the 522624th, Republic of China's patent gazette " charging method of rechargeable battery charging device, rechargeable battery set and secondary rechargeable battery ", it is a kind of when several rechargeable battery set are charged that its purpose will provide, can reduce the charging interval, and can produce the charging device of smaller size smaller.
More than two rechargeable battery charging methods disclosed rechargeable battery and how in the shortest time, effectively to have charged, but, for the user, rechargeable battery is before will using, how much must understand the actual charge volume of rechargeable battery in advance, how long just must charge again or change rechargeable battery in the back to carry out the decision operation power product, therefore, please consult Republic of China's patent gazette again No. 533646 " rechargeable battery charging system and rechargeable battery charging device thereof ", be to use one to have the microcontroller of drilling the translation routine plan, the charged state of supplying with rechargeable battery in order to monitoring produces a control signal, and supplies with suitable charging voltage and the electric current of rechargeable battery; Though this case has the function that detects the rechargeable battery capacity, in fact only do the process of one-time detection, it is full only to check that just rechargeable battery has or not, and can't accurately measure the capacity of rechargeable battery.
Can understand according to the above description, known technology can only judge that rechargeable battery has or not the detecting that reaches abundant saturation capacity, this part will not have too big help to the user, for instance, when need riding electric motor car, the user goes out, if do not know the actual charge capacity of rechargeable battery fully, can't judge actually and can ride how many distances, if will wait for that rechargeable battery is full of electric weight and how long does not also know to expend and produce greatly puzzlement, in addition, present system's use side (for example mobile phone) at miniature charging battery, behind system's use side in the rechargeable battery installing, though can show the charge capacity value in this rechargeable battery in real time, but for the user, if will carry a plurality of rechargeable batteries simultaneously, judge the entrained actual charge volume of each rechargeable battery again, because charger does not have the displaying ratio device, therefore, unless the user changes to system's use side one by one, otherwise can't learn this information at all, in view of this, how providing the user can obtain accurate electric weight ratio immediately and effectively on charger will be the problem that present charger is badly in need of solution.
Summary of the invention
Main purpose of the present invention, be to solve above-mentioned defective, existence for fear of defective, the invention provides a kind of charger that shows the rechargeable battery charge volume that possesses, mainly provide and add electric power and carry out power conversions the charging device that rechargeable battery charges is exported a shows signal after charging by charger, and on charging device, be provided with a display unit and receive this shows signal, by means of display unit rechargeable battery charging on the charging device action after, provide multistage electric weight ratio to show the actual charge value of finishing charging of rechargeable battery according to shows signal, formation one can be in real time and is accurately obtained to finish charge volume information like this, to allow the user can carry out the accurate judgement of rechargeable battery service time and distance.
Another object of the present invention is to charger is to add the electric power interrupt status outside, provide default reference electric quantity value after computing, to obtain the electric weight ratio that rechargeable battery reality has been finished charging by the actual charge capacity value of rechargeable battery feedback and this charger again, by charger this electric weight ratio is sent shows signal to a display unit again and inform that the accurate rechargeable battery of user finished charge capacity, therefore the present invention adopts and reads rechargeable battery charge capacity value separately and carry out interpretation, to do not added electric power and disturb and obtain accurate electric weight ratio, the user can feel at ease according to this information and effectively use.
