On the morning of September 26, 2020, after the operation department of China Railway 22nd Bureau Group Guangzhou Huangpu Tram Line 1 project issued a departure order, a brand new tram drove out of the subway Shuixi Station and the line was re-commissioned. The first tram project using "supercapacitor + lithium titanate battery" energy storage and power supply device has been completed and is currently undergoing trial operation and commissioning, laying the foundation for the full-scale operation at the end of the year.
This line uses the "super capacitor + lithium titanate battery" hybrid energy storage power supply device technology for the first time in the country. The line system super capacitor has a single capacity of 9,500 farads, which is currently the most mature and reliable super capacitor in China. When the vehicle arrives at the station, the vehicle will automatically complete the charge between passengers getting on and off the vehicle. It takes less than 30 seconds to achieve a dynamic balance of vehicle energy consumption and replenishment and ensure uninterrupted operation of the vehicle. At the same time, the vehicle is equipped with a lithium titanate battery to provide compensation and power supply for the vehicle in emergencies and emergencies, which greatly improves the emergency capability of the vehicle operation. Due to the use of "super capacitor + lithium titanate battery" as the energy storage device for traction and power supply, there is no contact web in the interval, which greatly reduces the "cobwebs" in the urban air. In addition, when the vehicle is braking, more than 80% of the braking energy is recovered to the super capacitor to form electric energy storage, which realizes energy recycling and achieves high efficiency and energy saving.
