Title
(EN) VEHICLE CHARGING SYSTEM AND VEHICLE
(FR) SYSTÈME DE CHARGE DE VÉHICULE, ET VÉHICULE
(ZH) 一种车辆的充电系统及车辆
Abstract
(EN)
A vehicle charging system, comprising a switch apparatus (30), a first direct-current battery (10), and a second direct-current battery (20). In the case that a supply voltage of a charging device is greater than or equal to a first voltage and less than a second voltage, the switch apparatus (30) controls the first direct-current battery to be connected in parallel to the second direct-current battery to implement low-voltage charging. Also disclosed is a vehicle comprising the charging system. The charging system improves the universality and commonality of the charging device, and reduces the construction cost of special charging devices for vehicles.
(FR)
La présente invention concerne un système de charge de véhicule comprenant un appareil de commutation (30), une première batterie à courant continu (10) et une seconde batterie à courant continu (20). Dans le cas où une tension d'alimentation d'un dispositif de charge est supérieure ou égale à une première tension et inférieure à une seconde tension, l'appareil de commutation (30) commande la première batterie à courant continu, devant être raccordée en parallèle à la seconde batterie à courant continu, de mettre en œuvre une charge à basse tension. La présente invention concerne également un véhicule comprenant le système de charge. Le système de charge améliore l'universalité et le caractère commun du dispositif de charge, et réduit le coût de construction de dispositifs de charge spéciaux pour véhicules.
(ZH)
一种车辆的充电系统,包括开关转换装置(30)以及第一直流电池(10)和第二直流电池(20),在充电设备的供电电压大于或等于第一电压且小于第二电压的情况下,通过开关转换装置(30)控制所述第一直流电池和第二直流电池并联,实现低压充电;在所述充电设备的供电电压大于或等于所述第二电压的情况下,通过所述开关转换装置(30)控制所述第一直流电池和第二直流电池串联,实现高压充电。还公开了一种包括该充电系统的车辆。该充电系统提高了充电设备的普适性、共用性,降低了车辆专用充电设备的建设成本。
