Problems solved by technology

However, this conventional charging method only compares the surface pressure of the battery pack with a threshold value, and therefore, when the surface pressure increases due to durability deterioration of the battery pack during charging, even if the battery pack is charged normally, it may pass the determination Occurrence of overcharge causing false interruption of battery pack charging

Abstract

A battery charging system including a battery is provided. The battery includes a plurality of battery cells that are stacked and a pressure sensor that is configured to detect a pressure caused by swelling of the battery cells. A charger supplies charging power to the battery and a controller determines whether to supply the charging power from the charger and whether the battery is overcharged based on a change in the pressure per hour, detected by the pressure sensor, when the charger supplies the charging power to the battery.

Description

technical field [0001] The present invention relates to a battery charging system and method, and more particularly to a battery charging system and method that diagnoses the cause of swelling in a battery cell within a battery during charging , and determine whether the battery pack is overcharged based on a diagnostic reason. Background technique [0002] As the problems of global warming and environmental pollution increase, research and development of eco-friendly vehicles capable of minimizing environmental pollution are actively being carried out in the field of the automobile industry, and the market thereof is gradually expanding. Examples of such eco-friendly vehicles include electric vehicles, hybrid electric vehicles, and plug-in hybrid electric vehicles for which electric motors are used to use electricity instead of using existing internal combustion engines (which generate power via the combustion of fossil fuels) power) to generate driving power. Among these...
