Specific embodiment
The exemplary embodiment that the present invention will be described in more detail below with reference to accompanying drawings.Although showing the present invention in attached drawing
Exemplary embodiment, it being understood, however, that may be realized in various forms the present invention without should be by embodiments set forth here
It is limited.It is to be able to thoroughly understand the present invention on the contrary, providing these embodiments, and can be by the scope of the present invention
It is fully disclosed to those skilled in the art.
Referring to Fig. 1, Fig. 1 is the flow chart of the embodiment of the method for present invention control battery charge, method includes:
Step 101: when the battery is in charged state, acquiring the voltage of the battery；
Charged state refers to battery receptacle to the state of charging current.And the charging current of battery is by small change in access
Big, default normal current is finally reached, therefore, the voltage for acquiring battery is the ability when charging current reaches default normal current
It executes.
Step 102: according to the voltage, controlling the charging current of the battery.
During charging, the temperature of battery increases battery, and the heat of battery increases, when battery when the temperature is excessively high,
Battery will appear the case where explosion or spontaneous combustion, therefore, it is necessary to which the charging current to battery controls, to avoid battery
Temperature is excessively high.And according to heat Calculation formula P=U*I, when charging current reaches default normal current, value is fixed, P
It is to change as U changes, therefore, the heat of battery can be determined according to the voltage U of battery, and then determine the temperature of battery
Degree can influence the peace of battery to avoid the temperature of battery excessively high according to the charging current that U controls battery on the contrary
Entirely.
Specifically, as shown in Fig. 2, controlling the charging current of the battery according to the voltage, further comprising:
Step 1021: according to the collected voltage of institute, judging whether the voltage of the battery increases, if so, executing step
1022, otherwise do not handle；
The voltage increase of battery refers to that the voltage of battery is in the trend risen, such as: before 1 minute, voltage 20V is existing
It is 22V in voltage, and voltage increases, in the trend of rising.
Step 1022: calculating the first voltage variable quantity of the battery in scheduled duration；
The specific value of scheduled duration is not construed as limiting, those skilled in the art may be set according to actual conditions, such as:
1 minute, 5 minutes etc..
Step 1023: judging whether the first voltage variable quantity is greater than default variable quantity, if more than the default variation
Amount, thens follow the steps 1024, otherwise, executes step 1025；
Default variable quantity is preset value, and specific value is not construed as limiting, and be may be set according to actual conditions.
Step 1024: the charging current of the battery is adjusted to default low current；
Step 1025: the charging current of the battery being made to remain default normal current.
Default low current is less than default normal current.When the voltage of battery is in rising trend, and first voltage variable quantity
When greater than default variable quantity, then illustrate cell heat suddenly strong rising, battery pole is easy to appear the risk of spontaneous combustion, therefore, in battery
Heat suddenly strong rising when, reduce the charging current of battery, the fever of battery can be reduced, amount of heat is avoided to build up, cause electricity
The risk of pond spontaneous combustion.When first voltage variable quantity is less than or equal to default variable quantity, then illustrate that the calorific value of battery is lower,
Default normal current can be kept to charge the battery, guarantee the charge efficiency of battery.
In some embodiments, adjust in the charging current of battery to default low current, if the calorific value of battery according to
It is so very high, then the charging of battery can be closed, in case there is security risk in battery, then as shown in Fig. 2, method further include:
Step 1026: continuing to obtain the second voltage variable quantity of the battery；
Step 1027: judging whether the second voltage variable quantity is greater than default variable quantity, if more than the default variation
Amount, thens follow the steps 1028, otherwise executes 1029；
Step 1028: closing the charging current of the battery；
When second voltage variable quantity is greater than default variable quantity, then when explanation is charged using default low current, electricity
The calorific value in pond is also excessively high, therefore, closes the charging current of battery, battery stops charging.Certainly, in some embodiments, when
The second voltage variable quantity is greater than default variable quantity, the excessively high prompt of output temperature, to prompt user, even if using low electricity is preset
Stream charges, and the temperature of battery is also very high.
Step 1029: the charging current of the battery being made to keep default low current.
When keeping default low current to charge the battery, electricity can be calculated in real time with the voltage of real-time monitoring battery
Variable quantity is pressed, variable quantity is preset when voltage variety is less than, the charging current of battery can be restored to default normal current, with
Guarantee the charge efficiency of battery.Certainly, when being charged the battery with default normal current, the voltage variety of battery is still
When less than default variable quantity, it can also be charged the battery using default largest battery, to further increase its charge efficiency.
In embodiments of the present invention, when charging the battery, the voltage of battery is detected, and according to the electricity of battery
Pressure, controls the charging current of battery, avoiding battery well, heat is flown up during the charging process, causes the temperature of battery
It is excessively high, draw the risk of its spontaneous combustion or explosion, compared with the existing technology in by temperature sensor detect battery temperature, and
The mode of charging current, the side that the embodiment of the present invention controls the charging current of battery are controlled according to the value of temperature sensor
Formula does not need temperature sensor, saves hardware cost.
The present invention also provides the Installation practices of control battery charge, referring to Fig. 3, controlling battery charge
