Battery module for frequency hopping device

This creation relates to a battery module, and more particularly to a battery module for a frequency hopping device.

1 is a schematic diagram of a conventional battery module 100' and a plastic housing 40' for a frequency hopping device. As shown in FIG. 1 , a power source generally used for providing a frequency hopping device is mounted in a plastic case 40 ′ to mount a battery module 100 ′. The battery module 100 ′ includes a lithium cobalt battery core 10 ′ and a circuit board. 20', electrode holder 30' and other sub-systems assembled.

When a frequency hopping device is used for going out, it is often necessary to carry a plastic casing 40' and three spare battery modules 100' for use by the frequency hopping device, and when the frequency hopping device is not used, The plurality of battery modules 100' are electrically connected for charging, and after being charged for a period of time, are stored in the warehouse and reserved for next use.

However, the battery module 100' used in the frequency hopping device does not have a capacitance display unit on the outer surface of the battery module. When the frequency hopping device is to be used, the battery module 100 is previously charged and placed in the warehouse. The battery module 100' is directly taken out and used. At this time, the user cannot immediately judge whether the battery module 100' has a capacity by the appearance of the battery module 100'. If the battery module 100' is damaged or insufficiently charged, the battery module 100' is insufficient in power. If the battery module 100' is carried in the above situation, the frequency hopping device cannot be powered normally. The battery module 100' is assembled separately from the outer casing 40', which causes inconvenience in replacing the battery module 100'.

In addition, the battery core 10' having a tandem lithium cobalt battery also has a risk of deflagration, which further increases the instability of the frequency hopping device.

Therefore, an improved battery module capable of effectively solving the above problems must be proposed to provide a more reliable and safer source of power for the frequency hopping device.

One of the purposes of this creation is to propose a battery module for a frequency hopping device as a power source for the frequency hopping device, which can effectively solve the problems caused by the appearance of the battery module without the capacitance display in the prior art.

In an embodiment of the present invention, the battery core is lithium iron phosphate.

In an embodiment of the present invention, the outer casing and the upper cover are packaged as the casing.

In an embodiment of the present invention, the battery module further includes a box body, and the box system is formed by a plurality of battery protection boards.

In one embodiment of the present invention, the protection circuit board has an automatic sleep mechanism.

In one embodiment of the present invention, the battery is serially connected in a manner of 5 strings and 7 pairs.

In one embodiment of the present invention, the outer casing is an ABS plastic outer casing.

Therefore, since the outer casing of the battery module proposed by the present invention includes a power display unit to display the capacitance of the battery, the user can instantly charge the battery module according to the capacitance displayed by the power display unit. At the same time, the protection circuit board of the creation can automatically enter the sleep state when the frequency hopping device is not used for a long time, so as to prevent the battery module from being over-discharged in an unused state. Furthermore, the battery of the creation is a lithium iron phosphate core, which has the characteristics of no deflagration and stable output, and can provide more reliable and safer power and standby power of the frequency hopping machine.
