AI Technical Summary

Technical Problem

In the prior art, when replacing a single battery module, the inconsistent state of charge of the battery modules leads to long balancing time and large energy loss. In addition, the active balancing circuit is expensive and not convenient for use in medical devices.

Method used

The module housing is divided into a basic housing and an additional housing. Combined with a compensation device and an active balancing circuit, it achieves low-loss balancing of the state of charge and dynamically adjusts the state of charge through a battery management system.

Benefits of technology

It enables rapid balancing of the state of charge of the battery module, reduces energy loss and cost, and supports the continuous and emergency operation of medical equipment.

Abstract

The medical device (1) has a battery memory, by means of which the continuous operation of the medical device is supported and / or the emergency operation of the medical device is enabled. The battery memory has multiple battery modules disposed in a module housing of the medical device. The power connection between the battery modules is determined by the arrangement of the battery modules in the module housing. The module housing is divided into multiple basic housings and at least one additional housing. The battery memory is associated with a compensation device. The compensation device is capable of balancing the basic state of charge and the additional state of charge with low loss between the battery modules disposed in the basic housings with a uniform basic state of charge and the battery modules disposed in the additional housings with an additional state of charge. However, the compensation device cannot induce a uniform basic state of charge within the battery modules disposed in the basic housings.
