Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clearly
Chu, it is fully described by.
Embodiment 1
A kind of method for charging batteries is present embodiments provided, as shown in figure 1, the processing stream of the present embodiment method
Journey is comprised the following steps：
Step 101, detection obtain the battery temperature of rechargeable battery.
In charging process, battery temperature can be raised battery, the reason for the rising of battery temperature a part be by
The heat energy of battery is converted into the electric energy for charging, a part is to generate heat to making battery in use due to terminal
The heat of itself increases.
Charging device should real-time detection rechargeable battery battery temperature, so when battery temperature is larger, fill
Electric installation can prevent the battery temperature of rechargeable battery from persistently raising to adjust charging method in time, cause one
A little potential safety hazards.
Step 102, the battery temperature be more than default temperature threshold when, by current charging current adjustment
For preset charged electric current is charged.
Wherein, the preset charged electric current is less than the current charging current.
Charging device shows when the battery temperature for detecting the rechargeable battery is more than default temperature threshold
To a higher level, now charging device will adjust charging method to the battery temperature, ought
Preceding charging current is adjusted to preset charged electric current and is charged, wherein, the preset charged electric current is less than described
Current charging current.Can play due to carrying out charging to battery with smaller charging current and battery is lowered the temperature
Effect, therefore when charging device is adjusted to preset charged electric current and is charged, the liter of battery temperature can be suppressed
It is high.So when battery temperature rises to temperature threshold, can also continue to be continued to charge with less electric current,
Avoid occurring after battery temperature is raised it is possible that be inserted with adapter always and problem that battery can not charge.
In charging process, if cell voltage reaches the specified limitation voltage of battery, charging device is just for battery
Can stop charging, when specified limitation voltage described here refers to rechargeable battery full charge, be further continued for charging,
Cell voltage will not also rise, and cell voltage now is referred to as specified limitation voltage.
Certainly, charging device is less than or equal to default temperature threshold in the battery temperature for detecting rechargeable battery
When, showing that the current battery temperature of rechargeable battery is not also very high, continuation is carried out according to existing charging method
Charge, until when cell voltage reaches the specified limitation voltage of battery, stopping charging.
Herein it should be noted that the temperature threshold described in the present embodiment method is general higher, example,
It can be 45 DEG C -52 DEG C；Preset charged electric current is the electric current that battery battery core allows to charge at relatively high temperatures, such as
0.5C or smaller, 0.5C are 0.5 multiplying power of charged battery capacity, and C (Capacity, battery capacity) is represented
Charged battery capacity, it is assumed that charged battery capacity is 1000mAh, then preset charged electric current represent for 0.5C
Charging current is 0.5*1000mA=500mA.
Embodiment 2
A kind of method for charging batteries is present embodiments provided, as shown in Fig. 2 the processing stream of the present embodiment method
Journey is comprised the following steps：
Step 201, detection obtain the battery temperature and cell voltage of rechargeable battery.
In charging process, battery temperature can be raised battery, the reason for the rising of battery temperature a part be by
The heat energy of battery is converted into the electric energy for charging, a part is to generate heat to making battery in use due to terminal
The heat of itself increases.
Charging device should real-time detection rechargeable battery battery temperature, so when battery temperature is larger, fill
Electric installation can prevent the battery temperature of rechargeable battery from persistently raising to adjust charging method in time, cause one
A little potential safety hazards.
In addition, rechargeable battery is in the case where battery temperature is larger, if cell voltage is too high, it is also possible to produce
The certain potential safety hazard of life, therefore charging device also needs to the cell voltage that detection obtains rechargeable battery, it is to avoid electricity
Charged under conditions of HTHP in pond.
Step 202, when the battery temperature is more than default temperature threshold, adjust the rechargeable battery
Limitation voltage is preset limit voltage.
Specified limitation voltage of the preset limit voltage less than rechargeable battery.
Charging device shows when the battery temperature for detecting the rechargeable battery is more than default temperature threshold
, to a higher level, for security consideration, now charging device can be described for the battery temperature
The limitation voltage of rechargeable battery is adjusted to the preset limit voltage less than specified limitation voltage, will limit voltage
Turn down.
Here, what preset limit voltage was set can not be too low, and to ensure battery when stopping charging, battery is electric
Amount be in higher level, meanwhile, preset limit voltage set can not be too high, it should for rechargeable battery compared with
The appropriate voltage for charging is allowed under high-temperature.By taking lithium battery as an example, the specified limitation voltage of lithium battery is generally
4.24V, preset limit voltage typically could be arranged to 4V.Typically according to different battery products, set out
Rational preset limit voltage.
Certainly, charging device is less than or equal to default temperature threshold in the battery temperature for detecting rechargeable battery
When, showing that the current battery temperature of rechargeable battery is not also very high, continuation is carried out according to existing charging method
Charge, until when cell voltage reaches the specified limitation voltage of battery, stopping charging.
Herein it should be noted that the temperature threshold described in the present embodiment method is general higher, example,
It can be 45 DEG C -52 DEG C.
Step 203, the cell voltage be less than the preset limit voltage when, by current charging current adjust
It is whole for preset charged electric current is charged.
When the cell voltage is less than the preset limit voltage, show that cell voltage is not also very high, go back
In the safe range for charging, still can continue to charge, now the charging device will can currently charge
Electric current is adjusted to preset charged electric current and is charged, wherein, the preset charged electric current currently fills less than described
Electric current.Can play a part of to lower the temperature battery due to battery charge with smaller charging current,
Therefore when charging device is adjusted to preset charged electric current and is charged, the rising of battery temperature can be suppressed.So
When battery temperature rises to temperature threshold, can also continue to be continued to charge with less electric current, it is to avoid hair
After raw battery temperature is raised it is possible that be inserted with adapter always and problem that battery can not charge.
The preset charged electric current is the electric current that battery battery core allows to charge at relatively high temperatures, such as 0.5C or more
It is small.
Step 204, the cell voltage be more than or equal to the preset limit voltage when, stop charge.
When the cell voltage is more than or equal to the preset limit voltage, show that cell voltage is too high,
In the case that the battery temperature exceedes temperature threshold, continue charging and be likely to result in some potential safety hazards, therefore stop
Only battery charges.
