Battery with redundant cell unit

Abstract

The invention discloses a kind of cell which has redundancy cell unit, which is made up by connecting several cells in series into cell group, the character lies in: the cell group has redundancy cell unit, the cell group outputs with limiting-pressure after through the constant pressure control circuit; each cell sets a independent switch circuit, the circuit can measure failure and cuts off the deficient cell unit. The independent switch circuit maintains the stability of cell performance, and it maintains the working of notebook computer, and it can provides enough voltage through the redundancy cell unit when the deficient cell is cut off, at the same time, it matches with the constant voltage control circuit, maintains the stability of output voltage, it only increases a rather small cost, but it can upgrades the performance of notebook computer cell prominently.

Description

technical field [0001] The invention relates to a battery device, in particular to a battery with redundant battery units, and belongs to the field of power supply devices. Background technique [0002] With the advancement of technology, a large number of smart devices are constantly produced. Among them, many devices can be carried along with people's travel. Although these portable devices are very different, they all have one feature in common: they all have rechargeable batteries; for example: notebook computers, personal digital assistants (Personal Digital Assistant, PDA), mobile phones and so on. At present, these smart devices basically use rechargeable batteries; this kind of rechargeable battery connects several battery cells in series, packs them together, and then provides power to the corresponding devices. Its advantages are: the stored electric energy is large and the volume is small. However, this battery, like other rechargeable batteries, has some probl...
