However, even if these battery packs with a fuel gauge are used, there is a problem that the remaining amount display is difficult to understand depending on the type of equipment using the battery. For example, a battery pack accommodating a plurality of lithium ion batteries is used as a power source for an electric drill, and the battery pack is fixed to a waist belt of a user of the electric drill, and the battery pack and the electric drill are connected by a cable. When connected by a power drill, the power drill user must look at the battery pack with the waist belt attached, and in some cases detach the battery pack from the waist belt. I had to check it. Also, when using the device in an environment where charging is not possible, for example,
When a device is used in an environment where the battery pack cannot be charged, such as when climbing the mountain, on the ocean, or in the news field, the battery pack will inevitably become large. It is connected by a cable keeping a certain distance. Even in such a case, the device user may not be able to directly see the fuel gauge of the battery pack.

On the other hand, it is conceivable to equip the device using the battery pack with a fuel gauge for the battery pack. However, in calculating the battery remaining amount, the battery remaining amount is calculated based on the battery characteristics used initially. Therefore, when you replace the battery pack with a new one, rechargeable batteries with slightly different battery characteristics may be used, resulting in inaccurate remaining battery calculation and displaying the accurate remaining battery capacity. There was a problem that I could not. There is also a problem that the remaining amount cannot be displayed unless the battery pack itself is attached to the device body.

A battery level indicator for displaying the level of the rechargeable battery based on the detection result of the detection circuit for detecting the voltage or current of the rechargeable battery is a connection between the battery pack and the device. It may be provided on any part of the cable,
It is preferable to provide it at a portion close to the device side so that the device user can directly see it. As the battery level indicator, like the remote control function of the headphone stereo, the connection cable and the display are integrated to display the remaining amount by the liquid crystal, and multiple light emitting diodes are stepwise according to the remaining amount. An example is a display unit that emits light, or a display unit in which the emission color of the light emitting diode changes depending on the remaining amount.

According to the present invention, since the connection cable itself is provided with the battery remaining amount display portion for displaying the remaining amount of the rechargeable battery, the battery pack and the equipment used have a fuel gauge. Even if it is not installed in advance, you can easily know the remaining battery level. Further, even a purchaser of a battery pack not equipped with a fuel gauge can check the remaining battery capacity by purchasing the battery pack connection cable of the present invention in the future. Furthermore, since the fuel gauge is separated from the main body, the purchaser of the battery pack only has to purchase the connection cable with the fuel gauge as necessary, and is not forced to spend extra money.
