Problems solved by technology
[0007] As the use time of the notebook computer increases, this phenomenon will cause the temperature of the battery (or battery pack) arranged at the front to be higher than that of other batteries (or battery packs), and its service life will naturally be shorter than other batteries. It may even lead to dangerous situations such as liquid leakage and air leakage in the battery module of the notebook computer, which poses a serious threat to the safety of users

Embodiment Construction
[0036] The first specific embodiment according to the present invention is a battery balancing device. In this embodiment, the battery balancing device is applied to a battery module of a notebook computer. The battery module includes a plurality of batteries and a plurality of switch units connected in series, wherein the plurality of batteries and the plurality of switch units are connected in series alternately, that is, a battery is connected in series between any two adjacent switch units and A switch unit is connected in series between any two adjacent batteries. Generally speaking, the plurality of batteries are usually lithium batteries, but not limited thereto. As mentioned in the prior art, a single lithium battery can only supply a voltage of 3.7 volts under normal conditions, so three (or more) lithium batteries must be connected in series to provide the voltage required for the notebook computer to operate.

The invention provides a battery balancing device which is applied to a battery module of a notebook computer. The battery module comprises a plurality of batteries connected in series and a plurality of switch elements. The battery balancing device comprises a first multiplexer, a second multiplexer, a switch module and a control module. The first multiplexer is coupled to the anode of each battery, and the second multiplexer is coupled to the cathode of each battery. The switch module is coupled to the switch elements. When cycle counting parameters received by the control module satisfy preset conditions, the control module can control the first multiplexer, the second multiplexer and the switch module to be in a specific mode to form a specific current path among the batteries.
Description
technical field [0001] The present invention relates to batteries of notebook computers, and in particular, relates to a battery balancing device capable of using each battery of a notebook computer on an equal basis to improve battery life and use safety and its operating method. Background technique [0002] In recent years, with the continuous development of science and technology, various computer devices have appeared on the market. Among all kinds of computer equipment, notebook computers have gradually become the mainstream of the market due to their small size, easy portability, and space-saving advantages, and they are also one of the indispensable tools in modern people's daily life. [0003] Generally speaking, a notebook computer can be powered directly by plugging in or by its battery module. In the battery-powered mode, the battery voltage required for the operation of the notebook computer is approximately in the range of 10.8 volts to 12.6 volts, but since a...
