NIVEAU DE CHARGE OU INTERVALLE DE RECHARGE AJUSTÉ PAR PERTE DE CAPACITÉ DE LA SOURCE D'ALIMENTATION RECHARGEABLE D'UN DISPOSITIF MÉDICAL IMPLANTABLE, SYSTÈME ET PROCÉDÉ
System and method for estimating the time before recharging the rechargeable power source of an implantable medical device. In a method, the present charge level of the power source is determined by determining the percentage of total charge consumed over a period of time. The present charge level is then divided by the expected power use to determine time remaining before recharging. Another method utilizes a model to determine the faded capacity of the rechargeable power source based on the number of times the rechargeable power source has been charged and the duration of the rechargeable power source's life.
