In the battery control method of the embodiment of the present invention, battery and electronic equipment, at low ambient temperatures, pass through current discharge, carry out powering load, and flow through battery itself by electric current and come to heating of battery, battery temperature is made to increase, but in whole heating process, meeting temperature current according to battery at any time determines the electric current of current power supply, the supply current that described battery utilizes this corresponding with temperature under Current Temperatures is for during to described load supplying, and the voltage of described battery is higher than the electric current of described cut-ff voltage.By said process, both ensure that the voltage of battery maintained on cut-ff voltage, improved battery temperature again, and made battery to enter operating state, avoided the adverse effect that special low temperature battery capacity is low and hot operation characteristic difference band is next.
The battery control method of the embodiment of the present invention is applied in a battery, described battery has a cut-ff voltage, and described battery is used for a load supplying, as shown in Figure 1, described battery control method comprises the following steps that circulation performs, until the temperature of described battery is more than or equal to the first temperature threshold:
Step 11, obtains the Current Temperatures of described battery;
Step 12, when the Current Temperatures of described battery is lower than the first temperature threshold, determines the current strength corresponding with described Current Temperatures;
Step 13, controls described battery to have the supply current of described current strength to described load supplying;
Wherein, described supply current be described battery under Current Temperatures to described load supplying time, make the voltage of described battery higher than the electric current of described cut-ff voltage.
In specific embodiments of the invention, when battery is with an electric current powering load, battery and load form a loop, and this supply current can flow through battery simultaneously, and the internal resistance of cell is when electric current passes through, and can produce heat, carry out heating battery.
And described battery is when exporting with larger electric current, because internal resistance own is larger, now output voltage can reduce, in a particular embodiment of the present invention, below cut-ff voltage is reduced in order to prevent cell voltage, the current strength of the supply current of described battery can be controlled, when to make under Current Temperatures to described load supplying, make the voltage of described battery higher than the electric current of described cut-ff voltage.
Above-mentioned process hockets, and the output voltage of battery can either be maintained on cut-ff voltage, and carrys out heating battery by the heating power of the internal resistance of cell simultaneously, realizes the lifting of battery temperature.
The battery control method of the specific embodiment of the invention makes common battery also can enter operating state at low ambient temperatures, to power electronic equipment, and special low temperature battery core need not be used, avoid the adverse effect that special low temperature battery capacity is low and hot operation characteristic difference band is next.
In a particular embodiment of the present invention, the supply current of battery can be changed by changing load, as in the initial period, only start a heating film (load), and after temperature is elevated to certain numerical value, start two heating films ..., until battery temperature is higher than the minimum temperature of normal need of work.
Usually, at low ambient temperatures, cell output is limited, and along with the increase of electric current, cell voltage will decline, and electric current increase to certain some time, voltage can be reduced to cut-off point, and battery will power-off.
That is, for a battery, corresponding to some battery temperature X (as subzero 30 degree), its discharging current has a maximum, described battery subzero 30 degree to described load supplying time, once supply current exceedes this maximum X, then its output voltage can be reduced under cut-ff voltage, battery is caused to enter the state that cannot use, and when being less than or equal to this maximum when battery is at subzero 30 degree to supply current during described load supplying, its output voltage can maintain on cut-ff voltage.
In addition, along with the rising of battery temperature, cell output also can improve gradually, and it maintains the maximum discharge current of output voltage on cut-ff voltage and also improves thereupon.

When determining at a first temperature to described load supplying, make the voltage of described battery higher than the maximum current of described cut-ff voltage;
Obtain the record sheet recording the corresponding relation of described maximum current and all temperature;
Then in following cycle process, all discharging current is determined according to this record sheet.
Due in follow-up cyclic process, battery temperature can continue to go up, and the maximum discharge current of its correspondence also can continue to increase, therefore, complete whole heating process with the maximum discharge current that minimum temperature is corresponding, output voltage must be maintained on cut-ff voltage.
< mode two >
In above-mentioned mode one, maximum discharge current corresponding to minimum temperature completes whole heating process, clearly, its heating process can be long, electronic equipment is enable to utilize battery to carry out work as early as possible in order to accelerate heating process, in mode two, all use at each temperature and corresponding with this temperature make the voltage of described battery higher than the maximum current of described cut-ff voltage, in whole like this heating process, at each temperature spot, all use the maximum output voltage of battery that makes to be kept above the maximum current of cut-ff voltage, therefore, it is possible to quickening heating process.
A kind of specific implementation of mode two is described as follows.
In mode two, determine in the step of the current strength corresponding with described Current Temperatures, especially by the record sheet searching a record temperature and current strength corresponding relation, obtain the current strength corresponding with described Current Temperatures, described record sheet describes at each temperature to the maximum current making the voltage of described battery higher than described cut-ff voltage during described load supplying.

For temperature X1 (as 40 degrees below zero), battery is positioned over environment lower a period of time that a temperature is X1, makes battery temperature consistent with ambient temperature;
One initial less discharging current is set;
With this discharging current to load supplying, after a period of time, judge that whether the output voltage of battery is higher than cut-ff voltage; Generally, if discharging current is less, now, the output voltage of battery, higher than cut-ff voltage, just can recover battery in this case, then increase discharging current, then return when judging to utilize the current discharge of this increase, whether the output voltage of battery, higher than cut-ff voltage, if still higher than cut-ff voltage, then continues to increase.
When continuing current flow increases to a certain degree, can find at some points, front nonrecoverable electric current lower than cut-ff voltage, now, can be recorded as the discharging current at this temperature by the output voltage of battery.
Temperature spot for other can use above-mentioned method to obtain, and does not repeat them here.
