Embodiment
It should be noted that, in the situation that not conflicting, the feature in embodiment and embodiment in the application can combine mutually.Below in conjunction with accompanying drawing, the present invention is described further.
Conventionally battery comprises structural member and is separately positioned on battery core, the control chip in structural member; battery core is made up of positive electrode, negative material, barrier film and electrolyte; in control chip, be provided with the current foldback circuit, overvoltage crowbar and the overcharge protection circuit that are connected with battery core; complicated control chip possesses the function with main-machine communication; its function comprises the output state that battery is set; comprise various overcurrents, overvoltage, the protection overcharging; and the reading of operating state to battery, such as battery electric quantity, battery temperature, internal resistance of cell etc.The model of these control chips have X2935 X2936 X2937, the DS2502 that also has Maxim to release, DS2782, DS2784, wherein DS2782, DS2784 has possessed the communication function with main frame, as shown in Figure 1, the IIC communication protocol that its basic hardware communication protocols is international standard, mainly on structural member, to be respectively equipped with the serial data line SDA terminal being connected with battery core, serial time clock line SCL terminal, positive source terminal and power cathode terminal, serial data line SDA terminal is connected with the central processing unit in main frame respectively with serial time clock line SCL terminal, the advantage of doing is like this that the contact point of battery and main equipment is few, only need two contact points.The present invention is in the technical foundation having had at these, in control chip, be also provided with battery operated state control circuit, by increasing the output state of battery, a work output state by the battery in past is increased to two or more battery operated output states, communicate by letter by IIC, according to the demand of main control device, change the output state of battery by main control device, reach like this optimum Match of main control device and battery.
Embodiment mono-
The present invention is arranged to two by the control chip on battery by the output state of battery, one is High-current output state, one is normalized current output state, conventionally battery is in normalized current output state, as shown in Figure 2, the method of improving battery impulse power supply of the embodiment of the present invention, comprises the following steps:
Step 2, control chip is received an order that changes electric current output state;
Step 3, the output state that battery operated state control circuit changes battery is automatically High-current output state, according to predefined set time when length gauge;
Step 4, control chip control battery core is exported large electric current;
Step 5, control chip is controlled battery core and is got back to original normalized current output state after a predefined set time length.
As another kind of execution mode, before step 2, increase again step 1: the time that main control device shifts to an earlier date 80-120ms sends by IIC or RS232 the order that changes electric current output state to control chip.Open so in advance the output thresholding of battery, so not only can in the large electric current of needs, prenotice battery and carry out output state change, optimize the process that electric current increases, shorten battery output current from little electric current to the needed time of large electric current, this is to improving the launching success rate of mobile device, reduce frame losing phenomenon and have larger help, concerning communication, the success rate that initial boot files (or header file) in the communication protocol that handheld device sends out is received completely by base station improves greatly, can well avoid the frame losing phenomenon of handheld device.
Embodiment bis-
The difference of the present embodiment and embodiment mono-is, as shown in Figure 3, also comprises to control chip and send the time span that this state keeps in described step 1; In step 2, also comprising that control chip has judged whether to receive the time span that this state keeps, is to enter step 6; No, enter 3;
Step 6, the output state that battery operated state control circuit changes battery is automatically High-current output state, the time span that control chip provides according to order is carried out timing;
Step 7, control chip control battery core is exported large electric current;
Step 8, after the time arrives, control chip control battery core is got back to original normalized current output state.
Adopt and change output state the mode that starts timing, can keep the time of current state output, in the situation that battery electric quantity is few relatively, handheld device can also proper communication, has extended the cruising time of battery, improves the success rate that base station receives completely.
To sum up, first the present invention needs to distinguish the needed large electric current or occurred the large electric current that unusual condition causes of transmitting, the output state of battery is divided into High-current output and two states of normalized current output, certainly, the output state of battery is changed into multiple, the different working stage of corresponding handheld device, as resting state, emission state, receives only state etc.Control chip is learning it is after signal is launched, battery status is transformed into High-current output state by battery operated state control circuit, and keep rational time span of this state, this rational time span is generally three times of signal transmitting duration, can be provided by handheld device, after time is up, battery is got back to normalized current output state automatically.
The invention solves when for a long time the overcurrent protection electric current of battery being arranged too greatly; while even exceeding with the needed transient current of satellite communication; current foldback circuit does not have the overcurrent protection function to battery and terminal equipment in the time of non-signal transmitting, likely damages terminal equipment, reduces the problem in terminal equipment life-span.If it is too low that overcurrent protection electric current arranges, the transmitting power of mobile device is too little, and the accuracy of impact and satellite communication, produces a large amount of error rates.
The above is the specific embodiment of the present invention, it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention, can also make some modifications, and these are revised and are also considered as protection scope of the present invention.
