Abstract

The battery heating system consists of an electrical heating resistance which can be installed inside or outside the battery case. The heater is designed to heat the battery electrolyte. The supply to the heater is taken from the battery terminals, both heater supply connections and heater are insulated from other battery components. Operation of the electric heater can be done manually or by appropriate means linked to the automobile ignition key when very low ambient temperature make it necessary.

Description

-1 - La présente invention concerne un dispositif permettant le-1 - The present invention relates to a device allowing the

réchauffage des batteries d'accumulateurs d'électricité afin d'augmenter la puissance obtenue aux bornes de celles-ci lorsqu'elles sont en situation de très basses températures ambiantes. A des températures normales, une batterie d'accumulateurs d'électricité  heating of electric storage batteries in order to increase the power obtained at the terminals thereof when they are in a situation of very low ambient temperatures. At normal temperatures, a storage battery

produit approximativement la puissance pour laquelle elle a été conçue.  roughly produces the power for which it was designed.

Lorsque la température d'une batterie descend en dessous d'un certain niveau, l'action génératrice du courant électrique se ralentit et elle ne débite plus la puissance attendue; d'o l'existence de certains ennuis rencontrés dans des 1o situations de très basses températures pour le démarrage des moteurs des véhicules notamment. Le dispositif selon l'invention, consiste à incorporer à l'intérieur même de la batterie ou à placer sur la face interne de ses parois, une résistance électrique dont l'action est sollicitée pour réchauffer la solution liquide qu'elle contient et les éléments qui la composent, ceci préalablement à la mise en marche du moteur au  When the temperature of a battery drops below a certain level, the generating action of the electric current slows down and it no longer delivers the expected power; hence the existence of certain troubles encountered in 1o situations of very low temperatures for starting the engines of vehicles in particular. The device according to the invention consists in incorporating inside the battery itself or placing on the internal face of its walls, an electrical resistance whose action is requested to heat the liquid solution which it contains and the elements that compose it, this prior to starting the engine at

Cette résistance est alimentée à partir des bornes mêmes de la batterie.  This resistor is supplied from the very terminals of the battery.

Le circuit d'alimentation de la résistance ainsi que cette dernière sont  The resistor supply circuit and the latter are

électriquement isolés des autres composants de la batterie.  electrically isolated from other battery components.

Lorsqu'une température trop basse exige qu'il soit fait usage de la résistance, la mise en fonction de celle-ci est commandée, soit, manuellement par l'utilisateur, lequel dispose d'un thermomètre lui indiquant le moment o la température atteinte par l'intérieur de la batterie est suffisante pour permettre un démarrage facile du moteur, soit, automatiquement par un dispositif approprié, commandé par la clef de contact du véhicule et ceci préalablement à la mise sous tension de tout autre  When a temperature that is too low requires the use of the resistance, the activation of this resistance is controlled, either manually by the user, who has a thermometer indicating when the temperature reached by the interior of the battery is sufficient to allow easy starting of the engine, either automatically by an appropriate device, controlled by the ignition key of the vehicle and this prior to the powering up of any other

élément tel que bougies de préchauffage ou démarreur.  element such as glow plugs or starter.

Le dispositif, objet de l'invention, trouve son application dans toutes les régions du monde o les basses tempértures, en réduisant la puissance disponible aux bornes des batteries d'accumulateurs d'électricité, posent des problèmes au  The device which is the subject of the invention finds its application in all regions of the world where low temperatures, by reducing the power available at the terminals of electricity storage batteries, pose problems to the

démarrage des moteurs des véhicules automobiles.  starting engines of motor vehicles.
