METHOD AND CHARGER FOR BOOST CHARGING A CHARGEABLE BATTERY ON THE BASIS OF A PHYSICAL MODEL
First Claim
1. Method of charging a rechargeable unit, such as a rechargeable battery or a rechargeable battery pack,wherein the charging current is larger than the nominal charging current (C) if at least one condition in the rechargeable unit is met,characterized in that the at least one condition is continuously calculated from measurable variables of the rechargeable unit through a physics-based model.

Abstract
The invention relates to a method of charging a rechargeable unit, such as a rechargeable battery or a rechargeable battery pack, wherein the charging current is larger than the nominal charging current (C) if at least one condition in the rechargeable unit is met, and wherein the at least one condition is continuously calculated from measurable variables of the rechargeable unit through a physics-based model. The invention also relates to a corresponding method. The features of the invention allow a continuous monitoring of the variables in the battery, so that a proper criterion is available for the decision if charging with high charge current is allowable without a reduction of the lifetime of the battery.
