Abstract
The present invention discloses a method for simulating a real battery charging process and a device thereof. The method comprises a step of presetting the capacity of a simulation battery, and calling the corresponding relation table of a known power capacity and output voltage, a step of obtaining charging current and charging time in the charging process, a step of periodically calculating the product of the charging current and the charging time to obtain an input capacity, a step of searching the corresponding relation table of the power capacity and the output voltage according to the input capacity to obtain output voltage, and a step of adjusting the output voltage of the simulation battery as the output voltage obtained by calculation. The device comprises a battery connector and a simulation power supply. The battery connector is connected to the charging chip of a rechargeable battery. The analog power supply comprises a data storage retrieval module, a current detection module, a clock module, a calculation module, and a voltage regulation module. According to the method and the device, the output voltage can be dynamically adjusted according to the magnitude of the charging current, the process of supplying power to the system by the rechargeable battery is simulated, and convenience is brought to a user to grasp the whole charging process.
Description
technical field [0001] The invention relates to the field of mobile terminal charging research, in particular to a method and device for simulating a real battery charging process. Background technique [0002] Since the smart device judges the power according to the battery voltage, for example, the battery voltage of a mobile phone is 3.6V, the corresponding power is 0%, and when the voltage is 4.2V, the corresponding power is 100%. There is a one-to-one correspondence between the battery voltage and the power. But not necessarily linear. Usually the corresponding relationship is as follows: [0003] 100%----4.20V; 90%-----4.06V; 80%-----3.98V; 70%-----3.92V; 60%-----3.87V; 50 %-----3.82V; 40%-----3.79V; 30%-----3.77V; 20%-----3.74V; 10%-----3.68V; 5 %------3.45V; 0%------3.00V. [0004] In the process of testing rechargeable battery equipment, it is necessary to know whether the relationship between battery capacity, charging current, charging time, and charging volta...
