Tramway news: Today, BYD officially issued a message that a pure electric bus operating in Shenzhen at the end of 2015 has driven more than 640,000 kilometers, refreshing the industry's operating data records, and the current vehicle condition is still good, providing high-quality travel services for Shenzhen citizens.
According to the data, BYD has delivered more than 70,000 pure electric buses worldwide, and has successively operated in Shenzhen, Guangzhou, Beijing, Shanghai, Hangzhou, Nanjing, Changsha, Xi'an, Dalian and other domestic cities, as well as well-known foreign cities such as London, Paris, Milan, Los Angeles, Kyoto, Tokyo, And Sydney, with a total mileage of more than 10 billion kilometers so far.
Hard power meets high demands
In the field of new energy vehicles, BYD has the biggest and most special advantage, that is, the core three electric technology is completely mastered by itself, and the batteries and motors supported by the vehicle are manufactured by itself. In the field of new energy buses, in the past two years, Zhongtong, Shenlong, Huanghai, FAW Toyota, Shudu and other enterprises have purchased power batteries or drive motors from BYD.
As a key component of pure electric buses, batteries not only affect the use and life of vehicles, but also directly related to the safety of vehicles.
The power battery cells, battery modules and battery systems used by BYD buses all take extremely high safety design and multiple safety protection measures, and carry out extreme tests such as fire, short circuit, needle punching, impact, extrusion, overcharge and other extreme tests from the battery cell to the battery pack, and the power battery system and controller protection level reach IP68+IP69 level, effectively ensuring the safety and stability of the vehicle battery under extreme conditions and high voltage safety.
Not only that, BYD pure electric bus is also equipped with its pioneering battery thermal management system, which has the characteristics of high temperature resistance, cold resistance, long life, high safety, easy maintenance, and wide application. For special environments such as low temperature in different regions and large temperature difference between day and night, the battery cell temperature is automatically controlled in the best range to ensure the best performance of different environments, extend service life, and ensure the quality of operation throughout the life cycle.
The bydir pure electric bus that set a new industry record was used for the daily operation of the Shenzhen M240 line. It is understood that the line is a city trunk bus, with large passenger flow, high frequency of departures, long lines and other characteristics, and has higher requirements for vehicle capacity, performance and reliability. BYD K8 with leading technology, ultra-high quality, low failure rate to effectively ensure the efficient attendance of vehicles, the line 71 shuttles are all K8, the average daily departure of 440 times.
It is under the strict technical standards that BYD pure electric buses can achieve operating mileage far beyond national standards, and at the same time can be highly recognized by customers at home and abroad.
Save more energy bills for bus companies
Although the promotion and application of new energy buses is a national energy conservation and emission reduction requirement, for public transport enterprises, it is not only necessary to consider energy conservation and emission reduction, but also to consider the actual cost of vehicles.
Because pure electric buses are generally equipped with larger batteries, so the price of vehicles is much higher than that of fuel vehicles, in the past few years, there has been a high amount of state subsidies to stimulate, and now the state subsidies have reached the point of negligible, and subsidies are about to be fully withdrawn, the cost of the whole life cycle of the vehicle is more important.
Tramway previously learned in the Shenzhen Eastern Bus Company that BYD's pure electric bus saves considerable energy costs, and from the perspective of the whole life cycle of vehicle operation, the cost of pure electric bus is more advantageous.
The bydir pure electric bus used by the company can also fully meet the operation needs of a day in the case of full air conditioning, which not only saves the trouble of building a large number of charging piles, but also can use the cheaper valley electricity to charge. The company uses 340 million kWh of electricity a year, and for every penny saved, it means saving up to 3.4 million yuan.
In the past, when using fuel buses, the average fuel consumption per vehicle per 100 kilometers was 42L, and the company's fuel unit price in 2019 was about 5.4 yuan. After replacing by BYD's pure electric bus, the electricity consumption of 100 kilometers is 105 degrees, and the charging unit price is 0.846 yuan. According to the difference between oil and electricity in Shenzhen, this item alone can save 1.3797 yuan per vehicle per kilometer, while the cumulative operating mileage of buses in eastern Shenzhen is about 360 million kilometers, and BYD pure electric buses can save 497 million yuan per year. In the past two years, the unit price of fuel has increased by more than 50%, and the electricity bill has not changed much, in this case, the advantages of pure electric buses are more obvious.
Although the current product energy consumption of various new energy bus companies is not much different, in theory, the energy cost that can be saved by bicycles every year is similar, but for the users of the vehicle, the longer the normal use of the vehicle, the more energy costs will be saved. From this point of view, BYD bicycles can maintain good vehicle condition after more than 640,000 kilometers of normal operation, and its cost advantages throughout the life cycle are self-evident.
