Abstract
(EN)
A power battery energy storage-type tramcar charging system and a charging method therefor, the system comprising: a tramcar (3) that extracts power from a contact rail (2) by using a pantograph (1); a charging control system used for supplying energy; a vehicle-mounted energy storage management system disposed within the tramcar (3); and a ground signal machine (8) disposed within a platform (7). The charging control system consists of a charger (4) and a ground charger controller (5); the contact rail (2) is connected to the charger (4) by means of a cable; and the charging control system and the tramcar (3) are both provided with a WIFI-AP. WIFI-AP technology is used to solve the difficult problem in which a large amount of data is transmitted in real time when a lithium battery is charged. Considering a situation in which uplink and downlink vehicles simultaneously enter a station, because wireless transmission has no directionality, the vehicle-mounted energy storage management system helps the charging control system to distinguish corresponding vehicles by obtaining current platform number information from a signal system, thereby solving the difficult problem of charging vehicle recognition.

La présente invention concerne un système de charge de tramway de type à stockage d'énergie par batterie d'alimentation et son procédé de charge, le système comprenant : un tramway (3) qui extrait de l'énergie d'un rail de contact (2) à l'aide d'un pantographe (1); un système de commande de charge utilisé pour fournir de l'énergie; un système de gestion de stockage d'énergie monté sur véhicule disposé à l'intérieur du tramway (3); et une machine de signal au sol (8) disposée à l'intérieur d'une plateforme (7). Le système de commande de charge est constitué d'un chargeur (4) et d'un dispositif de commande de chargeur au sol (5); le rail de contact (2) est raccordé au chargeur (4) au moyen d'un câble; et le système de commande de charge et le tramway (3) sont tous deux pourvus d'un point d'accès WIFI. La technologie des points d'accès WIFI est utilisée pour résoudre le problème difficile dans lequel une grande quantité de données est transmise en temps réel lorsqu'une batterie au lithium est chargée. Dans une situation dans laquelle des véhicules de liaison montante et de liaison descendante entrent simultanément dans une station, du fait que la transmission sans fil n'a pas de directionnalité, le système de gestion de stockage d'énergie monté sur véhicule aide le système de commande de charge à distinguer des véhicules correspondants en obtenant des informations de numéro de quai actuel à partir d'un système de signal, ce qui permet de résoudre le problème difficile de la reconnaissance du véhicule de charge.
