Abstract: PURPOSE: A non-catenary low floor tram system is provided to improve an urban aesthetic and to eliminate exhaust emissions by allowing a low floor tram to include a battery car and to be operated without supplying power through a catenary. CONSTITUTION: In case of a low floor tram(10) composed of five cars, a battery car(200) is installed in the middle, connected between a second car and a fourth car, and helps power to be smoothly supplied to a low floor vehicle(100). A pantograph(220) is installed on top of the battery car and drives the low floor tram or charges a lithium-ion battery(210) by using power supplied from a catenary(400) when the low floor tram travels in a catenary section.

Abstract: PURPOSE: A charge state management method for the battery of a non-catenary low floor tram is provided to completely collect regenerative energy generated during the braking of a vehicle and to allow the collected regenerative energy to be used for the driving of the vehicle or the operation of an auxiliary load like an SIV(Static Inverter) inside the vehicle, thereby improving the energy efficiency of a non-catenary low floor tram. CONSTITUTION: The charge state of a battery is managed by being classified into five regions of a critical high region(10), a high region(20), a normal region(30), a low region(40), and a critical low region(50). The critical high region and the critical low region are use-forbidden regions considered for the life of the battery, and since when the battery is frequently charged or discharged completely, the life of the battery is badly affected, and the energy storage performance and output performance are reduced. In order to prevent poor performance, the charge state of the battery is controlled not to enter into critical regions. The high region is a usable region not affecting the life of the battery, but a region not capable of absorbing 100% of the regenerative energy generated during the braking of a vehicle. The normal region is a middle region where frequent charging and discharging to allow the charge state of the battery to maintain a target charge state do not occur, and the charge state of the battery is controlled to stay at the normal region all the time. The low region is a region capable of absorbing 100% of the regenerative energy generated during the braking of a low floor tram, but when the low floor tram enters into a non-catenary section, only the battery energy can be used, so the battery is charged.

Abstract translation: 目的：提供一种用于非悬浮式低地板电车电池的充电状态管理方法，以完全收集在车辆制动期间产生的再生能量，并允许采集的再生能量用于车辆行驶或 在车内使用SIV（静态变频器）等辅助负载，提高非接地板低地板电车的能量效率。 构成：电池的充电状态通过分为临界高区域（10），高区域（20），正常区域（30），低区域（40）和临界低电压区域（40）的五个区域来管理 区域（50）。 关键的高电压区域和临界低电压区域是电池寿命考虑的禁止使用区域，而且由于当电池充电频繁或者充分放电时，电池的使用寿命受到很大影响，存储性能和输出 性能下降。 为了防止性能不佳，电池的充电状态被控制为不进入关键区域。 高区域是不影响电池寿命的可用区域，但是不能吸收车辆制动期间产生的再生能量的100％的区域。 正常区域是不会发生频繁充放电以使电池的充电状态保持目标充电状态的中间区域，并且电池的充电状态始终保持在正常区域。 低区域是能够吸收在低地板电车制动期间产生的再生能量的100％的区域，但是当低地板电车进入非悬链段时，仅可以使用电池能量，因此电池 被收费。 （附图标记）（AA）可用SOC范围;
