It is exemplary below by the embodiment being described with reference to the drawings, it is intended to for explaining the application, and the restriction to the application can not be interpreted as.
Below with reference to the accompanying drawings the charge control method of the embodiment of the present application, device and terminating unit are described.
First, in order to clearly each embodiment of the application is described, first, several nouns in the application are explained.
" the stopping potential value of charging chip " in the embodiment of the present application refers to according to the voltage rating serving as chip, being used for of can setting judges the benchmark value of battery whether charging complete, it is less than the safety voltage value of charging chip, is namely less than the load voltage value of charging chip. " reference voltage value " is that the application sets, and is used for judging that battery is the need of the benchmark value continuing charging, when the voltage of battery equals this benchmark value, then determines that battery has completed charging.
For example, if the voltage rating serving as chip is 4.35 volts (V), then stopping potential is considered after safe clearance, it is possible to be 4.25,4.2V or 4.18V etc.
Fig. 1 is the schematic flow sheet of the charge control method of the application's embodiment.
As shown in Figure 1, this charge control method comprises:
Step 101, judges whether the current magnitude of voltage of battery equals reference voltage value, and described reference voltage value is less than or equals the stopping potential value of charging chip.
Concrete, the charge control method that the present embodiment provides is configured in battery charge controller, and this battery charge controller can be the part in the terminating unit with rechargeable cell.
Specifically, in order to overcome the too high problem of battery charging voltage that the discordance due to charging chip brings. In the present embodiment, serve as control device and can first control charging chip, set a magnitude of voltage low or more equal than the stopping potential of charging chip, as benchmark value, then monitor the current magnitude of voltage of battery, and compare current magnitude of voltage and the size of reference voltage value.
Such as, it is noted that the type of terminating unit is a lot, it is possible to select as required: mobile phone, panel computer etc.
Step 102, if the current magnitude of voltage of described battery equals reference voltage value, then judges whether the charging current of described battery is zero.
Step 103, if not, then by reference voltage value described in the rule adjustment preset, until the charging current of described battery is zero.
Concrete, if battery control device determines battery, current magnitude of voltage equals reference voltage value, then whether the charging current that can monitor battery is zero, if zero, the magnitude of voltage that then battery of explanation charging chip monitoring is current equals reference voltage value, and has controlled to finish the process of charging to battery.
If and serve as control device and monitor charging current now and be not zero, then illustrate, battery is still being charged by charging chip, namely the current magnitude of voltage of the battery that now charging chip monitors is still lower than reference voltage value, then illustrate that the voltage sampling circuit of charging chip has deviation, make the magnitude of voltage monitored lower than actual value, now namely by adjusting the votage reference of charging chip, guarantee to make charging chip when the magnitude of voltage that battery is current equals benchmark value, terminate the process of charging to battery, thus ensure that battery can not be higher than normal stopping potential and charge.
For example, if the reference voltage value of initial setting is 4.2V, namely the reference voltage value in battery charger and charging chip is all 4.2V, so battery serves as device when to monitor the current voltage of battery be 4.2V, if determining, charging current is not zero, the voltage that then battery of explanation charging chip sampling is current is lower than 4.2V, may be such as 4.15V, then now the reference voltage value of charging chip can be turned down 4.15V, so that charging chip (serving as chip sampled voltage is 4.15V) when cell voltage is 4.2V, namely the process of charging to battery is terminated, thus ensure that battery can not by punching to higher than 4.2V, ensure that the reliability of battery.

Thus the charging voltage that ensure that battery can not higher than safety voltage, it is to increase battery serves as security and the accuracy of process, extends the life-span of battery.
Fig. 2 is the schematic flow sheet of another charge control method of the application.
As shown in Figure 2, this battery charging control method comprises:
Step 201, it is determined that described battery has entered the constant voltage charge stage.
Concrete, battery charging control device can the charging state of monitoring battery, after determining that battery enters the constant voltage charge stage, then monitor the size of battery current voltage value.
For example, battery charging control device, it is possible to according to the size of the current charging current of battery, it is determined that the charging stage that battery is currently residing. Or, it is also possible to according to the size of the current charging voltage of battery, it is determined that the charging stage that battery is currently residing. Namely above-mentioned steps 201 has following several way of realization:
Mode one:
Judge whether the current charging current of described battery is less than the value of setting;
If yes, it is determined that described battery has entered the constant voltage charge stage.
Concrete, due to usually after cell voltage reaches certain value, namely the constant voltage charge stage is entered, now the size of charging current can be determined, afterwards, charging current is more and more less, therefore whether can be less than the value of setting by comparing current charging current, judge whether battery has entered the constant voltage charge stage.
Mode two:

If yes, it is determined that described battery has entered the constant voltage charge stage.
Wherein, the scope preset is relevant with the constant voltage charge voltage of charging chip, if the constant voltage charge voltage of charging chip is 4.2V, then default scope can be between 4.18V to 4.02V etc.
