Based on the above hardware structure, various embodiments of the charging IC operation control method of the present application are provided.
Referring to fig. 2, a first embodiment of a charging IC operation control method according to the present application provides a charging IC operation control method, including:
step S10, the main control MCU compares the current remaining first electric quantity value of the battery with a preset electric quantity threshold value;
at present, many electronic devices have charging and discharging functions, that is, the electronic devices can be connected with an external power supply through a data line to charge the electronic devices; other external devices can also be connected via the data line and discharged, i.e. the external electronic device is charged. The present application takes an intelligent book as an example for explanation. When the battery power of the intelligent book is sufficient, if the intelligent book is used for ordinary charging of other external equipment, the external discharging efficiency is low; when the battery electric quantity of the intelligent writing book is low, if the battery of the intelligent writing book is continuously used for charging other external equipment, the damage to the battery is large, and the service life of the battery of the intelligent writing book can be shortened. In the embodiments of the present application, a charging IC operation control process of an intelligent book having both charging and discharging functions will be described with reference to the intelligent book having both charging and discharging functions as an example.
The charge IC operation control system comprises a main control MCU, a charge IC and a battery which are in communication connection; the main control MCU is used for comparing the current remaining first electric quantity value of the battery with a preset electric quantity threshold value; the charging device is also used for configuring a discharging mode of the charging IC according to a comparison result of the first electric quantity value and a preset electric quantity threshold; and the charging IC is used for operating in a state matched with the discharging mode according to the discharging mode.
When the intelligent book is used for charging and discharging, the data line of the intelligent book is needed. The data line of the intelligent book comprises 2 interfaces (the interfaces are distinguished according to the shapes) which are respectively a large interface and a small interface at two ends; the charging function of the intelligent writing book is realized by connecting an external power supply with a data line matched with the intelligent writing book, and an interface of the data line connected during charging of the intelligent writing book is a small interface; the discharge function is realized by connecting the data line adapted to the intelligent writing book with other external equipment, and the interface of the data line connected when the intelligent writing book is discharged is a large interface.
And the main control MCU configures whether the charging IC supports fast discharge, supports slow discharge or prohibits discharge according to the battery capacity. When the master control MCU configures the charging IC to support the fast discharge, the charging IC is in a fast discharge allowing mode; when the master control MCU configures the charging IC to support slow release, the charging IC is in a slow release allowing mode; when the main control MCU configures the charging IC to prohibit discharging, the charging IC is in a discharge prohibition mode. The current remaining first electric quantity value of the battery refers to the remaining electric quantity value of the battery of the intelligent writing book corresponding to the same moment when the intelligent writing book charges the connected external equipment; the preset battery threshold refers to a value that can be used to assist in determining what state the battery amount of the smart book is.
And step S20, the main control MCU configures a discharging mode of the charging IC according to the comparison result of the first electric quantity value and the preset electric quantity threshold value.
In the technical scheme disclosed by the application, the discharge modes of the charging IC comprise a fast discharge enabling mode, a slow discharge enabling mode and a discharge prohibiting mode. For example, when the discharge mode of the charging IC is the fast discharge enabled mode, the output voltage is 9V, and the output current is 2A; when the discharging mode of the charging IC is the fast discharging allowing mode, the output voltage is 12V, and the output current is 1.5A; when the discharging mode of the charging IC is the slow discharging allowing mode, the output voltage is 5V, and the output current is 1A; when the discharge mode of the charging IC is a discharge prohibition mode, no voltage is output to the outside.
In this embodiment, the main control MCU compares the current remaining first electric quantity value of the battery with a preset electric quantity threshold; and the main control MCU configures a discharging mode of the charging IC according to a comparison result of the first electric quantity value and the preset electric quantity threshold value. According to the method and the device, in the operation control process of the charging IC, the discharging mode of the charging IC is configured according to the comparison result of the current remaining first electric quantity value of the battery and the preset battery threshold value, so that the discharging mode of the charging IC is configured according to the electric quantity of the battery, the discharging efficiency of the battery is improved, and the service life of the battery is prevented from being shortened due to over-discharge of the battery.
Further, in the second embodiment of the charging IC operation control method of the present application, step S20 includes:
step S21, when the first electric quantity value is greater than the first threshold, configuring the discharge mode of the charging IC to be a fast discharge enabled mode; specifically, step S21 includes: transmitting preset fast discharge parameters to the charging IC through a bidirectional two-wire system synchronous serial bus I2C to configure the charging IC in the fast discharge enabled mode.
In the technical scheme disclosed by the application, when the first electric quantity value is larger than the first threshold value, namely the battery capacity of the intelligent book is sufficient, the external equipment can be rapidly discharged; the master MCU thus transmits the preset fast discharge parameters to the charging IC through the bidirectional two-wire synchronous serial bus I2C, thereby configuring the charging IC to allow the fast discharge mode.
When the battery electric quantity of the intelligent writing book is sufficient, if the intelligent writing book is used for discharging other external equipment slowly, the efficiency of discharging the external equipment is low.
It should be noted that, when the discharge mode of the charging IC is the fast discharge enabled mode, the charging IC operates in a state supporting fast discharge and slow discharge. The charging IC will determine whether to operate in a fast discharge enabled or slow discharge enabled state depending on the configuration of the charging device as needed.
Further, in the third embodiment of the charging IC operation control method of the present application, step S20 further includes:
a step S22 of configuring a discharge mode of the charge IC to be a slow discharge enabled mode when the first charge value is greater than the second threshold value and less than the first threshold value; specifically, step S22 includes: transmitting a preset slow release parameter to the charging IC through the bidirectional two-wire synchronous serial bus I2C to configure the charging IC in the slow release enabled mode.
In the technical scheme disclosed by the application, the preset battery threshold comprises a first threshold and a second threshold, and the first threshold is greater than the second threshold. For example, the first threshold is 50% and the second threshold is 5%.
When the first electric quantity value is larger than the second threshold value and smaller than the first threshold value, namely the battery capacity of the intelligent book is general, the external equipment can only be discharged slowly; the master MCU therefore transmits the preset slow release parameters to the charging IC via the bidirectional two-wire synchronous serial bus I2C, thereby configuring the charging IC to allow slow release mode.
It should be noted that, when the discharge mode of the charging IC is the slow discharge enabled mode, the charging IC operates in a state of supporting only the slow discharge state.
Further, in the fourth embodiment of the charging IC operation control method of the present application, step S20 further includes:
step S23, when the first electric quantity value is smaller than the second threshold, configuring the discharging mode of the charging IC as a discharge prohibition mode; specifically, step S23 includes: transmitting a preset discharge prohibition parameter to the charging IC through the bidirectional two-wire system synchronous serial bus I2C to configure the charging IC in the discharge prohibition mode.
In the technical scheme disclosed by the application, when the first electric quantity value is smaller than the second threshold value, namely the battery quantity of the intelligent book is too low, the intelligent book cannot discharge external equipment, otherwise, the battery can be damaged irreversibly; therefore, the master MCU transmits the preset discharge prohibition parameter to the charging IC through the bidirectional two-wire synchronous serial bus I2C, thereby configuring the charging IC in the discharge prohibition mode.
When the battery power of the intelligent book is low, if the battery of the intelligent book is continuously used for charging other external equipment, a series of adverse consequences can be caused, for example, the battery of the intelligent book is greatly damaged, and the service life of the battery of the intelligent book can be reduced; in addition, when the battery of the smart book is discharged until the battery is cut off, the RTC (real time Clock) Clock data of the smart book is lost. Moreover, when the intelligent writing book battery is recharged after being over-discharged, and the intelligent writing book needs to be charged, trickle charging is adopted at the initial charging stage, the charging speed is low, and the use experience of a user is influenced.
It should be noted that, when the discharging mode of the charging IC is the discharging prohibition mode, the charging IC operates in a state that the charging IC does not support the fast discharging and slow discharging states, that is, the battery is prohibited from discharging to the outside, so as to avoid the battery from being excessively discharged to shorten the service life of the battery, play a role in protecting the intelligent battery, and be beneficial to prolonging the service life of the intelligent battery.
Further, in the fifth embodiment of the charging IC operation control method of the present application, after step S20, the method includes:
step S30, when receiving the discharge stopping instruction of the charging IC, executing the step of configuring the discharge mode of the charging IC to the discharge prohibiting mode.
In the technical solution disclosed in the present application, when it is detected that the data line is pulled out, it means that external discharging needs to be stopped, and then the preset discharge prohibition parameter is transmitted to the charging IC through the bidirectional two-wire system synchronous serial bus I2C, so as to configure the charging IC in the discharge prohibition mode.
Further, in a sixth embodiment of the charging IC operation control method of the present application, the charging IC operation control method further includes:
step S40, when a charging instruction of the charging IC is received, acquiring a current remaining second electric quantity value of the battery;
in the technical scheme disclosed by the application, when the situation that the intelligent writing book is inserted into the small interface of the data line is detected, it is judged that the intelligent writing book receives a charging request of the battery, and the intelligent writing book needs to be charged by using a connected external power supply. The current remaining second electric quantity value of the battery refers to the corresponding intelligent writing battery remaining electric quantity value at the same time when the charging instruction of the charging IC is received.
A step S50 of executing the step of configuring the discharge mode of the charging IC to a discharge prohibition mode when the second charge value is smaller than the second threshold value;
in the technical scheme disclosed by the application, when the second electric quantity value is smaller than the second threshold value, the battery electric quantity is not enough to normally charge the external device, so that the discharging mode of the charging IC is configured to be the forbidding mode.
A step S60 of performing the step of configuring the discharge mode of the charge IC to be a slow discharge enabled mode when the second charge value is greater than the second threshold value and less than the first threshold value;
in the technical scheme disclosed by the application, when the second electric quantity value is larger than the second threshold and smaller than the first threshold, the battery electric quantity can be used for normally charging the external device, and therefore the discharging mode of the charging IC is configured to be the slow discharging mode.
Step S70, when the second electric quantity value is greater than the first threshold value, executing the step of configuring the discharge mode of the charging IC to be a fast discharge enabled mode.
In the technical scheme disclosed by the application, when the second electric quantity value is greater than the first threshold value, it indicates that the battery electric quantity can rapidly charge the external device, and therefore the discharge mode of the charging IC is configured to be the fast discharge allowed mode.
