[0002] In medical devices, external chargers and other charging devices are generally used to charge the rechargeable batteries of the medical devices.

[0003] Conventional medical equipment charging devices are chargers corresponding to a single rechargeable battery. When there are many rechargeable batteries, either multiple chargers are purchased to charge the rechargeable batteries one-to-one, resulting in a waste of resources, or one charger is used to charge the rechargeable batteries in turn, which is relatively inefficient. Using one medical equipment charging device to charge multiple rechargeable batteries at the same time can solve the above problems.

[0004] However, when a medical device charging device is used to charge multiple rechargeable batteries at the same time, a large amount of heat will be generated inside the medical device charging device. This heat accumulates and conducts inside the medical device charging device, causing the temperature of the internal components to rise, affecting the service life and reliability of the internal components themselves, thereby affecting the service life of the medical device charging device.

[0060] The battery cavity 102 is designed to gradually expand from the bottom to the top, so that the rechargeable battery 200 can be easily placed in the battery cavity 102 .

[0061] Specifically, when the rechargeable battery 200 is placed in the battery cavity 102 , a V-shaped groove 109 is formed between the rechargeable battery 200 and the side wall of the battery cavity 102 .
