Embodiment one
As shown in figure 3, in the present embodiment, a kind of charging/discharging thereof, comprising:
Battery temperature in S10, acquisition mobile terminal；
S20, judge whether the battery temperature is lower than preset temperature threshold；
If so, S30, unlatching heating module are battery heating；So that the battery temperature reaches preset temperature
Threshold value, to carry out normal charge and discharge；
Otherwise, S40, according to default rated current be battery charging and discharging.
In the present embodiment, it by the battery heating that heating module is under low temperature, allows battery battery core temperature to increase, promotes electricity
The lithium ion vigor of pond battery core improves battery efficiency, improves the available battery charge under current application mode.
In the present embodiment, the heating module includes resistive coil, has ultra-thin advantage, is laid in can be convenient
In mobile terminal, the resistive coil is laid in the surface of the battery.As shown in figure 4, for resistive coil (namely heater wire
Circle) artwork in mobile terminal.
In the present embodiment, the resistive coil can be by being attached on a face of battery after insulation processing, can also be with
It is attached on two opposite faces of battery, is heated by face, allow battery battery core fast lifting temperature, with can be under rated current
Charge and discharge are carried out, battery efficiency under low temperature environment is improved, improves the user experience of mobile terminal.
In the present embodiment, the size of resistive coil and the size of battery of mobile terminal are suitable, are in order to more efficient
Battery heating.
In the present embodiment, the control of heating module is realized by hand self-contained circuit, as shown in figure 5, before heating coil
End is provided with a load switch, which receives the control signal that mobile terminal AP is sent and opened and closed, when need
When heating for battery battery core, AP is heating by power supply of the battery after power management module PM by opening load switch
Coil power supply realizes the purpose of coil heats.
In the present embodiment, for transferring battery supply to load switch, PM is realized power management module PM herein
Isolation between load and battery.When low temperature charging, the isolation of charging output voltage and cell voltage is realized, system is being forbidden
When charging, realize battery supply and charger input charging BUCK power supply (VPH_PWR) isolation, and heating coil then from
Electricity is taken on VPH_PWR, when charger charging, the power supply of coil can take electricity from charger, without taking electricity from battery-end.?
Under discharge mode, load switch then passes through PM and directly takes electricity from battery-end.
As shown in fig. 6, in the present embodiment, the step S20 includes:
S21, when mobile terminal in charging mode, judge whether the battery temperature is lower than preset first temperature threshold
Value；
If so, S31, unlatching heating module, power for the resistive coil, heat for the battery；
Otherwise, S40, according to default rated current be battery charging and discharging.
In the present embodiment, first temperature threshold is preferably 15 DEG C, when system in charging mode, detect battery
Temperature is lower than 15 DEG C, system can opening coil heating module power supply, be coil power supply, heated for battery cell, allow electricity
Core temperature rises, and when temperature is more than 15 DEG C, system can be battery charging according to specified charging current, so as to improve terminal low
Bad experience that is slow or not charging of charging under temperature.When battery temperature after heating reaches 15 DEG C, is then closed from lower than 15 DEG C
Close heating module.
At this point, when mobile terminal detects that battery core temperature (can reduce bad charging electricity lower than 15 degree lower than 15 DEG C or 0 DEG C
Stream；It can stop charging lower than 0 degree；), the lithium ion liveness of battery core reduces, and when systems scan is to Current Temperatures, then it can open
Heating coil module, for battery core heat, thus drive battery core lithium ion liveness promoted, when temperature be higher than 15 DEG C, then can for electricity
Pond is charged according to 1C, and the latter then starts to charge for battery core according to 0.2C after temperature is higher than 0 DEG C.To realize under low temperature mode,
For the function of mobile terminal charging.
As shown in fig. 7, in the present embodiment, the step S20 further include:
S22, when mobile terminal in discharge mode, judge whether the battery temperature is lower than preset second temperature threshold
