Battery monitoring device and method thereof

Abstract

The invention relates to a battery monitoring device comprising at least one balancing module electrically connected with a plurality of batteries, wherein the plurality of batteries are connected with each other in series; the balancing module comprises a balancer and an electronic switch, wherein the electronic switch is used for electrically connecting the plurality of batteries to the balancer one by one, and the balancer is used for balancing the electric quantities among the plurality of batteries. In addition, the invention also relates to a battery monitoring method which can be used for balancing the electric quantities of the plurality of batteries, thereby improving the recharging and discharging qualities of the plurality of batteries.

Description

technical field [0001] The present invention relates to an electronic device, and in particular to a battery monitoring device and a method thereof. Background technique [0002] Components that store energy are very important to our lives, such as rechargeable batteries in portable electronic devices. Parts that store electrical energy affect the performance and working time of electronic devices. [0003] Generally speaking, rechargeable batteries have common electrochemical characteristics, that is, the chemical reaction is a reversible reaction, and the electrical energy can be converted into chemical energy through an external power supply, so that the discharged battery can be restored to its original state. Conversely, a battery cannot be charged if the chemical reaction is irreversible, as is the case with dry batteries. [0004] However, precautions need to be taken if several batteries are charged in series. Because of temperature changes or differences in batte...

Problems solved by technology

However, the current provided by the charger to each battery is the same, so it is conceivable that some batteries are fully charged while others are not fully charged.
