Title
(EN) AUXILIARY POWER OUTPUT FOR BATTERY MANAGEMENT SYSTEM
(FR) SORTIE DE PUISSANCE AUXILIAIRE POUR SYSTÈME DE GESTION DE BATTERIE
Abstract
(EN)
A utility cart includes a stored energy device that can be in the form of a Lithium Ion battery pack. The battery pack can include a main power output useful to drive high voltage components as well as the electric motor for motive power. The battery pack can also include one or more auxiliary outputs useful to provide auxiliary power to various other components. The auxiliary outputs can be either low and/or high voltage outputs. An auxiliary DC/DC output can be used to step down high voltage of the Lithium ion battery pack to lower voltages. A motor controller supply can also be provided as an auxiliary output to provide some power to a motor controller.
(FR)
Un chariot utilitaire comprend un dispositif à énergie stockée qui peut se présenter sous la forme d'un bloc-batterie au lithium-Ion. Le bloc-batterie peut comprendre une sortie de puissance principale utile pour exciter des composants à haute tension ainsi que le moteur électrique pour créer une puissance motrice. Le bloc-batterie peut également comprendre une ou plusieurs sorties auxiliaires utiles pour fournir une puissance auxiliaire à divers autres composants. Les sorties auxiliaires peuvent être des sorties basse et/ou haute tension. Une sortie CC/CC auxiliaire peut être utilisée pour abaisser la tension élevée du bloc-batterie au lithium-ion à des tensions inférieures. Une alimentation de dispositif de commande de moteur peut également être fournie en tant que sortie auxiliaire pour fournir une certaine puissance à un dispositif de commande de moteur.
