Detailed ways

As shown in Figure 2, a battery service time detection device is characterized in that it comprises:

The microprocessor controller is used to calculate the power consumption value of the electronic device in each time interval of the day and calculate the current remaining power value according to the above power consumption value to support the duration of use of the electronic device; through the electronic device The power consumption value in each time interval of a day can be used to understand the distribution of battery power consumption of the electronic device in a day (as shown in FIG. 1 ).

The memory is used for storing the power consumption value of the electronic device in each time interval of the day, and the memory is connected with the microprocessor controller.

The power detection module is used to detect the remaining power value of the battery at the current moment and send a power signal, the input end of which is connected to the battery and the output end is connected to the microprocessor controller; the microprocessor controller The remaining power value is obtained according to the received power signal.

The output current detection module is used to detect the output current value of the battery and send a current signal, its input terminal is connected to the battery and its output terminal is connected to the microprocessor controller. The output current detection module periodically detects the output current value of the battery and sends a current signal, the microprocessor controller knows the current output current value of the battery according to the received current signal, and according to the output current value, the microprocessor controller can calculate the power consumption value in each time interval of a day, so as to obtain the distribution of battery power consumption in a day. The time interval refers to dividing 24 hours of each day into several intervals, for example, divided into 24 intervals, and each time interval is 60 minutes. As shown in Figure 1, the 24 time intervals are T1 to T24 respectively; the power consumption values of each time interval are W1 to W24 respectively; the actual time of each time interval can be the whole hour, It can also be a non-hourly time. For example, the starting time of T1 may be from 0:00 to 1:00; the starting time of T2 may be from 1:00 to 2:00. The microprocessor controller can calculate the number of time intervals in which the remaining power can be consumed according to the remaining power value and the power consumption value of each time interval, so that the user can know that the remaining power of the battery can support The time the electronic device is used.

Further, a real-time clock chip (RTC, Real-TimeClock) connected with the microprocessor controller is also included. The microprocessor controller can obtain the current time by reading the data in the real-time clock chip. According to the current moment, the power consumption value of the time interval from the current moment can be calculated, so that the microprocessor controller can calculate the number of time intervals in which the remaining power can be consumed after the current moment, that is, the electronic device Availability of time from the current moment.

Further, a display module is also included, and the display module is connected with the microprocessor controller. The microprocessor controller calculates the number of time intervals consumed by the remaining power value after the current moment, and then controls the display module to display the calculation result. In this way, the user can know how long the electronic device can be used very conveniently.

Further, it also includes a voice prompt module, which is connected with the microprocessor controller. The sound prompt module is used to send out a prompt signal under the control of the microprocessor controller. When N is equal to or less than the reminding limit value, the microprocessor controller will send a control signal, and the sound prompt module will send out a prompt signal according to the control signal. The sound of "B-B" reminds the user to charge as soon as possible. Of course, the sound prompting module can also emit other sounds that can serve as prompts. The display module can also display relevant prompt information according to the control signal, such as text information such as "please charge as soon as possible".
