When the battery life is exhausted, but other hardware is available, it will cause waste if it is directly discarded. In addition, the batteries of integrated electronic products are also very difficult to separate, and recycling will cause additional labor costs and environmental pollution. Summary of the invention

[0003] The purpose of the present invention is to overcome the above-mentioned problems in the prior art and to provide a battery suitable for portable electric energy devices, which is easy to use, environmentally friendly and safe.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is: a battery suitable for portable electric energy equipment, including a matching battery body and a power interface device.

[0005] The battery body comprises a shell, a positive and negative power exchange interface A is provided on the shell surface, a card slot M is provided on the shell, and a magnetic body P is provided inside the shell;

[0006] The power interface device is arranged on the portable power equipment and is used to connect with the battery body for power exchange. The power interface device is provided with positive and negative power exchange interfaces B. The power interface device is divided into magnetic type and snap-on type according to different usage methods. The magnetic power interface device is provided with a magnetic body Q corresponding to the battery body.

[0029] It should be noted that when an element is referred to as being “mounted on” another element, it may be directly on the other element or there may be an element in the middle.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0031] like Figure 1 , Figure 2 As shown, an embodiment of the present invention provides a battery suitable for a portable electric energy device, including a matching battery body and a power interface device.

[0032] The battery body includes a shell, a positive and negative power exchange interface A is provided on the shell surface, a card slot M is provided on the shell, and a magnetic body P is provided inside the shell; the positive and negative power exchange interface A can be provided on the upper surface and / or the side of the shell to facilitate connection with a portable power device. The battery positive power exchange interface 1 is in the middle, the battery negative power exchange interface 2 is symmetrically arranged on both sides, and the battery temperature sensor interface 3 is symmetrically arranged on the outer side.

[0033] The power interface device is arranged on the portable power equipment and is used to connect with the battery body for power exchange. The power interface device is provided with corresponding positive and negative pole power exchange interfaces B and a temperature sensor interface 7. The power interface device is divided into a magnetic type and a snap-on type according to different usage methods. The magnetic power interface device is provided with a magnetic body Q corresponding to the battery body. After the magnetic body Q is connected with the magnetic body P by magnetic force, the battery body can be fixed and power exchange can be performed. The snap-on power interface device is provided with a card slot N corresponding to the battery body. After the card slot N is slidably connected with the card slot M, the battery body can be fixed and power exchange can be performed.

[0034] like Fig. 9 As shown, the battery body shell is equipped with a storage battery and a circuit board, and its control circuit includes a power control chip, a drive MOS tube, and a thermistor. The storage battery is connected to the positive and negative power exchange interface A on the shell through the power control chip and the drive MOS tube, and the thermistor is connected to the battery temperature sensor interface 3. The specific circuit connection diagram is shown in Fig.10 As shown, it works as follows:

[0035] During normal discharge, when the cell voltage is between 2.5V and 4.3V, the MOS tube is turned on and the battery discharges normally.

[0036] Over-discharge protection: When the cell voltage drops to 2.3V, the MOS tube is turned off, cutting off the discharge circuit. It will resume when the voltage rises back to 3.1V.

[0037] When the battery is charged externally, the power control chip detects the charging voltage, the MOS tube is turned on, and the battery is charged.

[0038] Overcharge protection: When the cell voltage rises to 4.4V, the MOS tube is turned off and charging stops. It resumes when the voltage drops to 4.3V.

[0039] Overcurrent protection: When the voltage drop between the D and S poles of the MOS tube exceeds 0.2V, the MOS tube is turned off and the discharge circuit is cut off.

[0040] Over-temperature protection: When the temperature is too high, the thermistor resistance drops, and the CPU of the portable power device issues a shutdown command to stop charging.

[0041] In the above embodiment, different numbers of driving MOS tubes can be connected in parallel according to the power demand of the peripherals connected to the battery body and the output capacity of the battery cells used. The greater the required output power, the greater the relative carrying capacity of a single MOS tube, and the more MOS tubes are connected in parallel.

[0042] In this embodiment, a charging pile of a battery body is provided for use, such as Fig.11 As shown, a vertical magnetic connection method is used when charging the battery, which saves more space.

[0043] The battery body can be designed as a power supply battery for daily low-power electrical energy devices, such as mouse, remote control, flashlight, etc.; the battery body can be designed as a power supply battery for daily medium-power electrical energy devices, such as power bank, wireless keyboard, shaver, etc.; the battery body may be designed as a power supply battery for daily high-power electrical energy devices, such as kettle, portable refrigerator, robot, card computer, outdoor power pack, etc.

[0044] Finally, it should be pointed out that the above embodiments are only representative examples of the present invention. Obviously, the present invention is not limited to the above embodiments, and there are also multiple solutions. Any simple modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention should be considered to belong to the protection scope of the present invention.
