In an embodiment, the transformation parameters of at least one first transformation circuit on one battery protection board are different. In another embodiment, at least two first voltage transformation circuits on one battery protection board have the same voltage transformation parameters.

In addition, in an embodiment, the transformation parameters of all the first transformation circuits on the at least one battery protection plate are different.

The processor 13 is configured to obtain a voltage requirement of the electronic device 1, and control a state of each first transformer circuit and a state of each second transformer circuit based on the voltage requirement.

It should be appreciated that the voltage requirement in embodiments of the present application may be the voltage requirement of the load 14 in an electronic device, such as a flashlight, radio frequency module, or display module in an electronic device; but may also be the voltage requirement of the battery. When the voltage demand is that of a load 14 in the electronic device, the battery supplies power to the load; when the voltage demand is a battery in the electronic device, the external power source supplies power to the battery.

In one embodiment, the processor 13 is configured to obtain a first transformation parameter of each first transformation circuit and a second transformation parameter of each second transformation circuit; the processor 13 is further configured to control the first voltage transformation circuit to be in an operating state and control each of the second voltage transformation circuits to be in an off state if the first voltage transformation circuit is determined to meet the voltage requirement based on the first voltage transformation parameter. For example, the electronic device 1 needs 3V, 2.5V and 2V voltages, three first voltage transformation circuits on at least one battery protection board 11 can provide 3V, 2.5V and 2V voltages, and a second voltage transformation circuit on the main board 12 can provide 3V, 2.5V and 2V voltages, and then the processor 13 controls the first voltage transformation circuits capable of providing 3V, 2.5V and 2V to be in an operating state and controls each second voltage transformation circuit to be in an off state.

In another embodiment, the processor 13 is configured to obtain a first transformation parameter of each first transformation circuit and a second transformation parameter of each second transformation circuit; if the first transformation parameters and the second transformation parameters are based, determining that part of the first transformation circuits in the battery protection board circuit and part of the second transformation circuits in the main board circuit meet the voltage requirements, controlling the first transformation circuits meeting the voltage requirements to be in a working state, and controlling the first transformation circuits except the first transformation circuits meeting the voltage requirements to be in a closing state; the second voltage transformation circuit which meets the voltage requirement is controlled to be in an operating state, and the second voltage transformation circuit which meets the voltage requirement is controlled to be in a closing state. It should be understood that if the voltage requirements are met by all of the voltage transforming circuits on the battery protection board 11 or the main board 12, it is not necessary to shut down either one of the first voltage transforming circuits or either one of the second voltage transforming circuits.

For example, the electronic device 1 needs 3V, 2.5V and 2V voltages, the first voltage transformation circuit on the at least one battery protection board 11 can provide 3V and 2V voltages, the second voltage transformation circuit on the main board 12 can provide 3V, 2.5V and 2V voltages, and the processor 13 controls the two first voltage transformation circuits capable of providing 3V and 2V to be in operation, and controls the three second voltage transformation circuits capable of providing 3V, 2.5V and 2V to be in operation. It should be understood that if a voltage transformation circuit capable of other voltages, for example, 4.5V or 3.5V, etc., is provided on the battery protection board 11 or the main board 12, the voltage transformation circuit capable of providing a voltage of 4.5V or 3.5V, etc., is controlled to be in an off state.

In yet another embodiment, the processor 13 is configured to obtain a first transformation parameter of each first transformation circuit and a second transformation parameter of each second transformation circuit; if the first transformation parameters and the second transformation parameters are based, determining that part of the first transformation circuits in the battery protection board circuit and part of the second transformation circuits in the main board circuit meet the voltage requirements, controlling the first transformation circuits meeting the voltage requirements to be in a working state, and controlling the first transformation circuits except the first transformation circuits meeting the voltage requirements to be in a closing state; and controlling the second voltage transformation circuit which meets the voltage requirement to be in a working state, and controlling the second voltage transformation circuit to be in a closing state, wherein the second voltage transformation parameter is the same as the first voltage transformation parameter of the first voltage transformation circuit which meets the voltage requirement and the second voltage transformation circuit which meets the voltage requirement except the first voltage transformation parameter.

For example, the electronic apparatus 1 requires voltages of 3V, 2.5V, and 2V, the first voltage transformation circuit on the at least one battery protection board 11 can supply voltages of 3V and 2V, the second voltage transformation circuit on the main board 12 can supply voltages of 3V, 2.5V, and 2V, the processor 13 controls the two first voltage transformation circuits capable of supplying 3V and 2V to be in an operating state, controls one second voltage transformation circuit capable of supplying 2.5V to be also in an operating state, and controls the two second voltage transformation circuits capable of supplying 3V and 2V to be in an off state.

In yet another embodiment, the processor 13 is configured to obtain a first transformation parameter of each first transformation circuit and a second transformation parameter of each second transformation circuit; based on the voltage requirement, the first transformation parameter and the second transformation parameter, the first transformation circuit and the second transformation circuit which meet the voltage requirement and correspond to the transformation parameters with the same first transformation parameter and the same second transformation parameter are controlled to be in a working state periodically.

For example, the electronic apparatus 1 requires voltages of 3V, 2.5V and 2V, the first voltage transformation circuit on the at least one battery protection board 11 is capable of providing voltages of 3V and 2V, the second voltage transformation circuit on the main board 12 is capable of providing voltages of 3V, 2.5V and 2V, the processor 13 controls the two first voltage transformation circuits capable of providing 3V and 2V to be in operation during the first half period of one cycle, controls the two second voltage transformation circuits capable of providing 3V and 2V to be in operation during the second half period of one cycle, and controls the one second voltage transformation circuit capable of providing 2.5V to be in operation all the time.

In order to avoid turning on the first transformer circuits with the same transformation parameters, the processor is used for controlling the state of each first transformer circuit and the state of each second transformer circuit in at least one first transformer circuit with different transformation parameters. In this way, the control mode of the processor can be simplified.

In the embodiment of the invention, the battery protection board and the main board are respectively provided with the voltage transformation circuits, and the processor can control the state of the first voltage transformation circuit positioned on the battery protection board and the state of the second voltage transformation circuit positioned on the main board according to the voltage requirement, so that the main board and the battery protection board can supply power to a load instead of supplying power to the load only through the voltage transformation circuit positioned on the main board, and the phenomenon of overhigh temperature of the main board is avoided; in addition, the first voltage transformation circuit is arranged on the battery protection board, so that the structure of the main board circuit is not required to be changed, and the structure of the electronic equipment is simple.

It should be understood that the number of first circuit parameters received by the processor 23 corresponds to the number of battery protection boards 21. For example, when the number of the battery protection plates 21 is k, since the first temperature detection circuits are provided on each of the battery protection plates 21, the number of the first temperature detection circuits is k, the processor 23 receives k first circuit parameters, and acquires k first temperatures from the k first circuit parameters.
