Currently, when developing or testing products with built-in batteries, power supplies or customized real battery boxes are used. But there are often many problems that are difficult to overcome.

The power supply can only simply supply power and cannot monitor and record the entire process or automatically adjust the power supply conditions. The development and production of customized battery boxes are usually produced in parallel with the product. Even the battery box sample takes one to two months to make the mold, so it is not conducive to testing the battery function of the product.

Testing the function of the battery box often requires actual samples before testing whether the function of the battery box meets the needs of the product. It is usually necessary to design a customized battery function test program for a product, but a customized battery function test program can only be suitable for the same type of product. When the types of products are different, new battery function test programs need to be developed again, which results in a lot of waste of resources.

Since the product and the battery box are tested at the same time, there are often internal factors that interfere with the test results, causing many uncertainties in the test results, and even doubts about lack of credibility. Furthermore, sample battery boxes are usually scrapped after product development is completed, resulting in a waste of resources.

The technical problem to be solved by this disclosure is to provide a battery status monitoring device and a control method thereof in view of the shortcomings of the existing technology.

The memory is electrically connected to the microprocessor and stores a plurality of virtual register items and a plurality of virtual register values respectively corresponding to the virtual register items. The first switch circuit is connected between the microprocessor and the development machine. The second switch circuit is connected between the microprocessor and the battery. The mode switching interface is connected to the microprocessor, wherein when the mode switching interface is in the first state, the first switch circuit is turned on and the second switch circuit is turned off so that the battery status monitoring device is in a virtual battery mode, and the microprocessor is used to convert the data corresponding to the development The virtual register value of a request command from the machine is responded to the development machine. When the mode switching interface is in the second state, the first switch circuit is turned off and the second switch circuit is turned on so that the battery status monitoring device is in the virtual development machine mode, and the microprocessor is used to monitor the register value of the battery.

In order to solve the above technical problems, another technical solution adopted by the present disclosure is to provide a control method of a battery status monitoring device for simulating the operating status of the battery and the operating status of the development machine, including: When the mode switching interface receives an external command, it sets the state of the mode switching interface according to the external command; according to the state of the mode switching interface, it sets the operating mode of the battery status monitoring device; when the mode switching interface is in the first state, the battery status monitoring device only communicates with Develop electromechanical connection, the battery status monitoring device is in the virtual battery mode, and is used to respond to the development machine with a virtual register value corresponding to the request command of the development machine; and when the mode switching interface is in the second state, the battery status monitoring device only Electrically connected to the battery, the battery status monitoring device is in a virtual development machine mode and is used to monitor the battery's register value.

One of the beneficial effects of this disclosure is that the battery status monitoring device and its control method provided by this disclosure can enable products and batteries to be developed and produced simultaneously, and each can be tested and analyzed independently, which can greatly reduce the waste of sample battery boxes. When the product is mass-produced or tested and verified, a more stable testing environment can be provided.

In step S915, the charging parameters stored in the memory 102 are reset according to the control command of the remote device RM, and step S917 follows. In step S917, charging of battery B is stopped, and then the process returns to step S903. When there is no control instruction from the remote device RM, step S917 follows.

For example, the user can set various charging parameters for 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. When battery B When the voltage does not reach 1800mV, the charging circuit 103 charges battery B at 180mA. When the voltage of battery B does not reach 4400mV, the charging circuit 103 charges battery B with 1500mA. When the voltage of battery B reaches 4400mV, charging circuit 103 charges battery B with 50mA.

As shown in Table 2, Table 2 is a charging parameter table of battery temperature-maximum charging voltage-maximum charging current. When the voltage of battery B does not reach 1800mV, the charging circuit 103 charges battery B with 180mA. When the temperature of battery B is lower than -10 degrees or higher than 55 degrees, the charging circuit 103 does not charge battery B. When the temperature of battery B is between -10 degrees and 0 degrees, the maximum charging voltage and maximum charging current of battery B by charging circuit 103 are 4200mV and 1000mA respectively. When the temperature of battery B is between 0 degrees and 45 degrees, the maximum charging voltage and maximum charging current of battery B by charging circuit 103 are 4400mV and 1500mA respectively.
