Title
(EN) APPARATUS, SYSTEM AND METHOD FOR A SELF-HEATING BATTERY CIRCUIT
(FR) APPAREIL, SYSTÈME ET PROCÉDÉ POUR UN CIRCUIT DE BATTERIE AUTO-CHAUFFANT
Abstract
(EN)
The disclosed exemplary apparatuses, systems and methods may provide a self-heating battery circuit, that comprises: a high voltage battery having terminals, and a parasitic internal resistance (R1) and a parasitic terminal inductance (L1); a resonant circuit connected across the battery terminals suitable to generate high alternating currents about its resonant frequency, fr; an energy superposition unit connected across a capacitance of the resonant circuit, and including a switch (K1), wherein K1 is switched on and off at the resonant frequency, fr, and at a first duty cycle pursuant to a switch control signal, thereby generating a high alternating current through the high voltage battery.
(FR)
Les appareils, systèmes et procédés donnés à titre d'exemple selon l'invention peuvent fournir un circuit de batterie auto-chauffant, qui comprend : une batterie haute tension ayant des bornes, et une résistance interne parasite (R1) ainsi qu'une inductance de borne parasite (L1) ; un circuit résonant connecté aux bornes de la batterie approprié pour générer des courants alternatifs élevés autour de sa fréquence de résonance, fr ; une unité de superposition d'énergie connectée à travers une capacité du circuit résonant, et comprenant un commutateur (K1), K1 étant allumé et éteint à la fréquence de résonance, fr, et à un premier cycle de service à la suite d'un signal de commande de commutation, générant ainsi un courant alternatif élevé aux bornes de la batterie haute tension.
