Abstract
The invention provides an identification method of a charger for a battery. An information base is previously stored in the main control circuit of the charger. The method comprises the steps: the control circuit arranged in the battery collects the model of the battery and state information, converts the information into a pulse signal of a characteristic frequency, and sends the pulse signal to the main control circuit of the charger through a circuit switched on when the charger is used for charging the battery; and the main control circuit of the charger receives the pulse signal and identifies the model and battery state information of the battery embedded in the charger referring to the information base according to the frequency of the pulse signal. The invention defines different batteries and battery states through different pulse signals so that the charger more correctly and more comprehensively identifies the battery embedded therein, the charger not only identifies the model of the battery, but also identifies the state information of the battery, thus, the charger automatically adjusts to adapt to the battery in the charging process, so as to prevent damage to the battery caused as the charging parameter and battery parameter are inconsistent in the charging process and prevent the battery from explosion.
Description
Technical field
The present invention relates to the recognition methods between a kind of charger and the rechargable battery.
Background technology
Adopting rechargeable battery is the fine selection that improves resource utilization at present, avoids the waste battery contaminated environment; In the equipment of various use rechargeable batteries; Possibly use dissimilar battery pack, different types of battery pack electric parameter is inconsistent, needs charger to treat with a certain discrimination.Present solution on the market is to increase in the battery pack to distinguish resistance, with the different dissimilar battery pack of resistance value difference.This kind methodological function is single, can not be with the out of Memory notice charger of battery pack.
Summary of the invention
The technical problem that the present invention will solve provides a kind ofly can discern the recognition methods of inserting the battery information in the charger automatically.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of charger stores information bank in advance to the recognition methods of battery in the charger governor circuit, the battery size and the battery status information that include pulse signal frequency information in this information bank and match with frequency information,
Described method step is:
The control circuit that is arranged in the battery is collected this battery size and battery status information, is the pulse signal of CF with information translation, and the circuit of conducting sends this pulse signal to the charger governor circuit when charging with charger through battery;
The charger governor circuit receives this pulse signal, and identifies the battery size and the battery status information of inserting in the charger according to the frequency contrast information bank of pulse signal;
This battery status information is battery current electric quantity information and temperature information.
Wherein, but be provided with the circuit of three conductings between charger and the battery, be respectively charging electrode line, ground wire and order wire, wherein, the charging electrode line is formed charge circuit to battery charge with ground wire, order wire and ground wire composition communication loop transmission pulse signal.
The present invention makes charger through different battery and the battery statuss of different pulse signal definition
To insert wherein battery identification more accurately, more comprehensive; Both can discern the model of battery; Also can identify the various state informations of battery; Like temperature, current electric quantity etc., thereby being regulated automatically, charger when charging adapt to this battery, avoided because problems such as charge parameter and the inconsistent battery damage that causes of battery parameter during charging, battery explosions.
Description of drawings
Accompanying drawing 1 is that embodiment of the invention charger connects sketch map with battery circuit.
Embodiment
For the ease of those skilled in the art's understanding, will combine specific embodiment and accompanying drawing that structural principle of the present invention is described in further detail below:
To the shortcoming of communicating by letter between charger in the prior art and the battery; What the present invention proposed is a kind of method that can identify more battery informations; So that charger when rechargeable battery is charged output voltage, electric current more meet the current requirement of battery, avoid damaging rechargable battery.
Among the present invention, in the charger governor circuit, store information bank in advance, the battery size and the battery status information that include pulse signal frequency information in this information bank and match with frequency information.
Thus, the circuit of conducting when being provided with three chargings between charger and the battery is respectively charging electrode line, ground wire and order wire.Wherein, charging electrode line and ground wire are formed charge circuit to battery charge, and order wire and ground wire are formed communication loop and transmitted pulse signal.Governor circuit received communication loop pulse signal in the charger also can contrast with the information bank data, is used to identify battery corresponding battery model and battery status information.
The step of recognition methods is:
At first, the control circuit that is arranged in the battery is collected this battery size and battery status information, is the pulse signal of CF with information translation, and the circuit of conducting sends this pulse signal to the charger governor circuit when charging with charger through battery;
Then, the charger governor circuit receives this pulse signal, and identifies the battery size and the battery status information of inserting in the charger according to the frequency contrast information bank of pulse signal.
The method of present embodiment can be battery size information and battery current electric quantity information and temperature information etc. to the information that charger provides, and charger is adjusted charge parameter according to this information through governor circuit.In charging process, can make it at interval that certain hour sends pulse signal automatically through setting to battery control circuit, make charger can be real-time the battery status information of electrolytic cell, in time adjust charge parameter.
As shown in the table is that charger governor circuit information bank content is given an example, and for different battery pack, the battery status informations different according to battery pack are provided with correspondent frequency:
This shows; The present invention is through different battery pack and the battery statuss of different pulse signal definition, make charger to insert wherein battery pack identification more accurately, more comprehensive, both can discern the type information of battery; Also can identify the various state informations of battery; Like temperature and current electric quantity etc., thereby being regulated automatically, charger when charging adapt to this battery, avoided because problems such as charge parameter and the inconsistent battery damage that causes of battery parameter during charging, battery explosions.
The governor circuit of the charger that present embodiment is related and the control circuit in the battery can improve a little at existing charger governor circuit and battery control circuit and get final product; Because of this improvement is easier to realize to those skilled in the art, do not do at this and give unnecessary details.
