Lithium titanate battery fast charging technology -Lithium - Ion Battery Equipment
What is the current level of lithium titanate battery technology? Which application field is more suitable for? The reporter recently investigated the bus companies in Handan, Shijiazhuang and Baoding in Hebei Province, which were hit hard by smog. The reporter of Auto News said that the fast charging technology of lithium titanate battery is very suitable for the operation of new energy buses, and he is optimistic about the application prospects of this technology.
■Quick charging technology route is suitable for public transportation
The reporter of "my country Automobile News" found in the survey that the public transportation systems of the three cities of Handan, Shijiazhuang and Baoding have chosen Yinlong lithium titanate battery new energy buses. Among them, the 1,000 pure electric buses of Handan Bus are all Yinlong brand, which has achieved 100% pure electric bus coverage of the bus line in the main urban area; Shijiazhuang Bus currently has 1,018 pure electric buses also all from Yinlong; Baoding Bus has purchased 10 An antique car of Yinlong lithium titanate.(Lithium - Ion Battery Equipment)
The three cities in the smog-stricken areas all choose Yinlong lithium titanate battery buses. What technical advantages does Yinlong have? Wei Cangyin, chairman of Yinlong, has previously publicly stated that Yinlong New Energy has mastered the world's excellent lithium titanate core technology, It has overcome the "five major problems" recognized by the industry, and achieved excellent characteristics such as 6-minute fast charging, wide temperature resistance, 30-year cycle life, no fire and no explosion. Among them, the fast charging technology of lithium titanate battery has become one of the factors that bus companies are very optimistic about in actual operation.
"The mode of Yinlong lithium titanate pure electric bus with small battery and short driving range is especially suitable for public transportation." Meng Yan, director of the technical equipment department of Shijiazhuang Public Transportation Corporation, said, "The bus line length in Shijiazhuang is generally 20 to 30 kilometers back and forth. The operation characteristics of fixed point and fixed line are very suitable for fast charging technology. It can be fully charged in 6 to 8 minutes without turning on the air conditioner and heater, and it can be fully charged in up to 15 minutes when the heater is turned on. The direct benefit of this is that it will not affect the bus line. normal operation." According to Meng Yan, the car was fully charged when the driver got out of the car and walked around the corner.
This fast charging method is in sharp contrast with the slow charging method of lithium iron phosphate, ternary lithium and other batteries. According to Xu Shixin, director of the Handan Public Transport Technology Department, since the bus has a punctuality rate of 5 to 8 minutes, the new energy vehicles using lithium iron phosphate batteries can be charged for 2.5 hours at a time. In order to ensure the punctuality rate, two drivers are required to drive three times. Only the proportion of buses allocated can ensure the smooth operation of the line. In addition, due to the long charging time, it is necessary to assign a special person to manage it, which also occupies human resources. These problems do not exist for fast charging.
■Lithium titanate battery is more cost-effective
Regarding lithium titanate batteries, there have always been many doubts in the industry about the short driving range and high cost of pure electric batteries. In this regard, Cao Chunguang, director of the technical equipment department of Baoding Public Transportation Corporation, made it clear that he did not feel that the cost of lithium titanate battery buses was high. He emphasized that the cost of bus operation should be calculated according to the entire life cycle of the vehicle, and it should be comprehensively considered from various aspects such as vehicle purchase cost, labor cost, and maintenance cost. "The longest bus line in Baoding is 30 to 40 kilometers back and forth. The driving mileage is not necessary for that long, and there is no need to install so many batteries." Cao Chunguang said.
