As shown in fig. 4, in step S401, the remote apparatus RM reads the data stream from the batterystate monitoring apparatus 1, followed by step S403. In detail, when the register value of the battery B is within the normal range, the batterystatus monitoring apparatus 1 transmits only the register value to the remote apparatus RM. When the register value of the battery B is not within the normal range, the data stream transmitted from the battery status monitor 1 to the remote device RM includes the register value and the warning message. In step S403, the screen of the remote apparatus RM displays the data flow of the batterystatus monitoring apparatus 1, followed by step S405. In detail, the remote device RM is installed with a battery monitoring application for displaying the register values and the warning information.

In step S503, themicroprocessor 101 determines whether there is a control instruction of the remote apparatus RM. When there is a control command from the remote device RM, step S505 follows. In step S505, themicroprocessor 101 updates the virtual register value in the virtual register list corresponding to the control command of the remote device RM, and then returns to step S503.
When there is no control instruction from the remote device RM, step S507 follows. In step S507, themicroprocessor 101 reads the virtual register value corresponding to the request command of the developer DUT in the virtual register list, and then in step S509. In step S509, it is determined whether the virtual register value is a fixed value. When the value of the dummy register is a fixed value, step S511 follows. In step S511, themicroprocessor 101 responds with the virtual register value to the developer DUT, and then returns to step 503.
If the value of the dummy register is not a fixed value, step S513 follows. In step S513, themicroprocessor 101 updates the virtual register value according to the predetermined variation every predetermined period, and then proceeds to step S515. In step S515, themicroprocessor 101 responds to the developer DUT with the updated virtual register value every predetermined period, and then returns to step S503.
For example, the user can directly set the first virtual register value of thememory 102 of the batterystatus monitoring apparatus 1 to be a variable value and set the second virtual register value to be a fixed value by the battery status monitoring program installed in the remote apparatus RM. The setting of the first virtual register value includes a predetermined period, a lower limit of the register value, and an upper limit of the register value with a predetermined variation. The developer DUT periodically transmits the request command, and when the developer DUT transmits the first request command to the batterystatus monitoring device 1, themicroprocessor 101 responds the updated first virtual register value to the developer DUT every predetermined period because the first virtual register value is automatically updated every predetermined period according to the predetermined variation. When the developer DUT sends a second request command to the batterystatus monitoring apparatus 1, themicroprocessor 101 reports a second virtual register value corresponding to the second request command to the developer DUT.
Fig. 6 is a flowchart of a control method of the remote device according to the present disclosure when the battery status monitoring device is in the first virtual battery mode. As shown in fig. 6, in step S601, a virtual register list of the battery status monitor is loaded. In step S603, the remote device RM determines whether there is an external control command.

In step S607, the remote device RM transmits the updated virtual register value to the batterystatus monitoring apparatus 1, and then returns to step S603.
When there is no external control instruction, step S609 follows. In step S609, it is determined whether the virtual register value is set to a fixed value. When the value of the dummy register is set to a fixed value, step S611 follows. In step S611, the virtual register value is maintained, followed by step S613. In step S613, the remote device RM transmits the virtual register value to the batterystatus monitoring apparatus 1, and then returns to step S603.
When the value of the dummy register is set to a non-constant value, step S615 follows. In step S615, the battery status monitor automatically updates the virtual register value according to the predetermined variation every predetermined period, and then step S617. In step S617, the battery status monitoring program transmits the updated virtual register value to the batterystatus monitoring apparatus 1 every predetermined period, and then returns to step S603.

The battery state monitoring program is provided with a virtual register list, and the virtual register list comprises a plurality of virtual register items and a plurality of virtual register values respectively corresponding to the virtual register items. When the user inputs an external control command to the mobile communication device to modify the first virtual register value in the virtual register list of the battery status monitoring program, the battery status monitoring program will transmit the modified first virtual register value to the batterystatus monitoring device 1, and themicroprocessor 101 of the batterystatus monitoring device 1 will update the first virtual register value stored in thememory 106, so that the first virtual register value stored in thememory 106 is identical to the first virtual register value of the battery status monitoring program of the remote device RM. When the user sets the second virtual register value in the virtual register list of the battery status monitoring program to change every 1000ms, the battery status monitoring program of the remote device RM transmits the updated second virtual register value to the batterystatus monitoring device 1 every 1000ms, and themicroprocessor 101 of the batterystatus monitoring device 1 updates the second virtual register value stored in thememory 102, so that the second virtual register value stored in thememory 102 is the same as the second virtual register value of the battery status monitoring program of the remote device RM.
Fig. 7 is a flowchart of a control method of the battery status monitoring apparatus in the second virtual battery mode according to the present disclosure. When the virtual battery mode of the batterystatus monitoring apparatus 1 is the second virtual battery mode, as shown in fig. 7, in step S701, the virtual register list in thememory 102 is loaded. In step S703, themicroprocessor 101 reads the virtual register value corresponding to the request command of the developer DUT in the virtual register list, and then in step S705. In step S705, it is determined whether the value of the dummy register is a fixed value. If the value of the dummy register is a fixed value, step S707 follows. In step S707, themicroprocessor 101 responds to the developer DUT with the virtual register value, followed by step S709. In step S709, it is determined whether the batterystate monitoring apparatus 1 is connected to the remote apparatus RM.
When the batterystate monitoring device 1 is connected to the remote device RM, step S711 follows. When the batterystate monitoring device 1 is not connected to the remote device RM, the process returns to step S703.
In step S711, the batterystatus monitoring apparatus 1 transmits the virtual register value to the remote device RM so that the remote device RM can display the virtual register value from the batterystatus monitoring apparatus 1 on the screen, and then returns to step S703.
When the value of the dummy register is not a fixed value, step S713 follows. In step S713, themicroprocessor 101 updates the virtual register value in the virtual register list according to the predetermined variation every predetermined period, and then step S715. In step S715, themicroprocessor 101 responds to the developer DUT with updated virtual register values every predetermined period, followed by step S717. In step S717, it is determined whether the batterystate monitoring device 1 is connected to the remote device RM. When the batterystate monitoring device 1 is connected to the remote device RM, step S719 follows. In step S719, the batterystatus monitoring apparatus 1 transmits the virtual register value to the remote apparatus RM so that the remote apparatus RM can display the virtual register value from the batterystatus monitoring apparatus 1 on the screen, and then returns to step S703. When the batterystate monitoring device 1 is not connected to the remote device RM, the process returns to step S703.
In other embodiments, steps S709 to S711 and steps S717 to S719 of fig. 7 may be omitted.

When the first virtual register value in the virtual register list is set to be updated every 1000ms according to the set value variation (for example, the value variation is 800), the batterystatus monitoring apparatus 1 responds the updated first virtual register value to the developer DUT every 1000 ms.
Fig. 8 is a flowchart of a control method for the battery status monitoring apparatus in the first virtual development machine mode according to the present disclosure. When the virtual development machine mode of the batterystate monitoring apparatus 1 is the first virtual development machine mode, as shown in fig. 8, in step S801, the virtual register list in thememory 102 is loaded. In step S803, the register value of the battery B during the discharging process is read. In step S805, it is determined whether the battery state monitoring apparatus is connected to the remote apparatus RM. When the batterystate monitoring apparatus 1 is not connected to the remote apparatus RM, the process returns to step 803. When the batterystate monitoring apparatus 1 is connected to the remote apparatus RM, step 807 follows. In step S807, the batterystatus monitoring apparatus 1 transmits the register value of the battery B during the discharging process to the remote apparatus RM, so that the remote apparatus RM can display the register value of the battery B during the discharging process on the screen, and then returns to step S803. In detail, when the batterystate monitoring apparatus 1 is in the first virtual development machine mode, the user can set the power consumption parameter of the electronic loader EL, and the electronic loader EL will draw the power to the battery B according to the power consumption parameter. At this time, the batterystate monitoring apparatus 1 can monitor each register value of the battery B during the discharging process.
Fig. 9 is a flowchart of a control method for the battery state monitoring apparatus in the second virtual development machine mode according to the present disclosure. When the virtual development machine mode of the batterystate monitoring apparatus 1 is the second virtual development machine mode, as shown in fig. 9, in step S901, the charging parameters in thememory 102 are loaded. In step S903, it is determined whether the batterycondition monitoring apparatus 1 is connected to the remote apparatus RM. When the batterystate monitoring device 1 is connected to the remote device RM, step S905 follows. In step S905, the charging parameters stored in thememory 102 are updated according to the control command of the remote device RM, and then step S907 follows. In step S907, the chargingcircuit 103 is set according to the charging parameters stored in thememory 102.
When the batterystate monitoring device 1 is not connected to the remote device RM, step S907 follows. After step S907, step S909 follows. In step S909, the chargingcircuit 103 charges the battery B, followed by step S911. In step S911, the register value of the battery B during charging is read, and then step S913 is performed. In step S913, it is determined whether or not there is a control command from the remote apparatus RM. When there is a control instruction from the remote apparatus RM, step S915 follows. In step S915, the charging parameters stored in thememory 102 are reset according to the control command of the remote device RM, and then step S917 follows. In step S917, charging of battery B is stopped, followed by returning to step S903. When there is no control instruction from the remote apparatus RM, step S917 follows.
For example, the user can set various charging parameters for the battery B in the battery status monitoring program of the remote device RM, as shown in table 1, table 1 is a charging parameter table for constant current-constant voltage charging, and when the voltage of the battery B is less than 1800mV, the chargingcircuit 103 charges the battery B with 180 mA. When the voltage of the battery B does not reach 4400mV, the chargingcircuit 103 charges the battery B with 1500mA. When the voltage of battery B reaches 4400mV, the chargingcircuit 103 charges battery B with 50 mA.
(Table 1)
As shown in table 2, table 2 is a table of charging parameters of battery temperature-maximum charging voltage-maximum charging current. When the voltage of battery B is less than 1800mV, chargingcircuit 103 charges battery B with 180 mA. When the temperature of the battery B is lower than-10 degrees or higher than 55 degrees, the chargingcircuit 103 does not charge the battery B. When the temperature of the battery B is between-10 degrees and 0 degrees, the maximum charging voltage and the maximum charging current of the chargingcircuit 103 to the battery B are 4200mV and 1000mA, respectively. When the temperature of the battery B is between 0 degrees and 45 degrees, the maximum charging voltage and the maximum charging current of the chargingcircuit 103 to the battery B are 4400mV and 1500mA, respectively.
