What is the objective of baojun bus

On July 1st, the buffer period for early withdrawal of subsidies will end, and both manufacturers and direct users will enter a new stage of substantial reduction of subsidies.

During the development of new energy vehicles in China, the public transport sector has absorbed the most new energy buses. Facing the coming new situation, what are the thoughts of public transport enterprises? Song cong, deputy general manager of changsha baojun bus co., said: "slow charging can take advantage of peak and valley electricity prices, but the problems of building a large number of charging piles, meeting scheduling requirements and battery attenuation are a headache. Quick charge is the opposite. "Taking all factors into consideration, the slow charge and fast charge buses of baojun bus will remain at 1:1 in the future.

Social as well as economic benefits

Baojun bus is a private bus enterprise, as a public service unit, social benefits must be placed in the first place. "Government departments have assessment indexes for bus operations," song said. "the attendance rate of new energy buses must exceed 90 percent.

The new energy bus with slow rechargeable battery is easy to meet the attendance standard in the evening rush hour. After a night of slow charging, the new energy bus's power is enough to cope with the morning rush hour. However, the continuous driving distance of the slow charging new energy bus generally cannot meet the requirements of the bus. In order to solve this problem, they take the way of replenishment at noon. Due to the long charging time, it is impossible for all cars to recharge at the same time. There must be operating vehicles on the road to ensure the attendance rate. The new energy buses that are charged cannot be "reborn with blood".

New energy bus on the road "chain" will affect the operation of the whole line. It is the rush hour of work. If one new energy bus breaks down on the road, it may cause traffic jam on the whole road. If two or three buses break down on the road at the same time, the situation will be even worse. People complain so much that they go to the mayor's mailbox to complain. In addition, bus companies have operating subsidies, and if they fail to meet attendance requirements, government departments will have corresponding deductions. "We love and hate slow charge nev buses." Song Cong said.

Local governments have played a positive role in the promotion of new energy buses in local areas. In particular, local governments that have attracted investment from new energy vehicle manufacturers have spared no effort to strongly support them, and generally require bus enterprises to accept a certain number of new energy buses. Subsidies for lithium iron phosphate electric buses strength is very large, and local subsidies, the cost of new energy bus dropped substantially, around the replacement of new energy bus does not increase too much burden, after all, the use of new energy bus cost is much lower than traditional car, most bus companies still willing to contribute to environmental protection.

According to song cong, when the changsha municipal government assigned the task of 1,000 new energy buses, baojun bus has purchased 200 slow-charging buses. At present, baojun bus has 719 buses, 375 of which are new energy buses. "" 175 quaichong buses were purchased last year and this year. Song Cong said.

After years of comparison, the new energy buses for baojun bus to reduce the cost of a contribution. According to song cong, CNG gas buses cost 190 yuan per 100 kilometers, plug-in hybrid buses are 160 yuan and pure electric buses are 53 yuan. Pure electric buses can take advantage of peak-valley electricity prices. From 8:00 a.m. to 7:00 a.m. the next day, the electricity price in changsha is 0.41 yuan per kilowatt hour. "It is difficult to achieve social and economic benefits at the same time," song said. By chance, we learned about the fast-charging bus, which hit our sweet spot. Last year and this year, baojun bus purchased 175 buses equipped with micro macro quick rechargeable batteries.

Quick charge bus operation advantages

Unlike state-owned bus companies, which receive free land for construction sites, baojun buses must buy their own land. However, slow charging buses need to build a large number of charging piles. If all the charging needs of electric buses are met, the site of baojun bus is obviously not available. Quick charging buses don't require a lot of charging piles. "" quick charging buses hit a sore spot for us by saving charging piles and occupying land. Song Cong said.

According to song, the buses are bisected, which requires each station to build charging piles. If there is no charging pile at a station, the slow-charging bus will not be able to be charged there and will not be able to be on duty the next day. Baojun bus purchase micro macro quick charge bus does not exist in this problem. Song cong said: "micro macro quick charging bus equipped with 138 KWH, can run two back and forth to recharge, even stopped at the station without a charging pile overnight, the next day as usual out of the car, back to the station with a charging pile to charge on the line. In this way, it is not necessary to build a large number of charging piles at each station, but only one charging pile can be built at one end of each line, which saves a lot of cost of pile construction.

At the beginning of the promotion of new energy vehicles in China, the subsidy amount of lithium iron phosphate battery bus was very high, reaching up to 500,000 yuan, while the quick charging bus was only 160,000 yuan, which was a big gap between the two. As the subsidy goes down, the economic advantage of the lithium iron phosphate battery gradually recedes, and the economic advantage of the quick charging bus appears. Song cong told China automotive news that, excluding subsidies, a slow-charging bus with lithium iron phosphate costs almost twice as much as a fast-charging bus.

Battery attenuation is a headache for all users. Song cong has been tortured by battery attenuation for many times. Song cong told China automotive news that battery attenuation has been found in the lithium iron phosphate electric buses purchased by baojun bus, which has been used for more than a year. Baojun bus signed a quality assurance agreement with the main engine factory, and after the attenuation, the main engine factory will transport the vehicle back to the factory to replace the battery. "It will take several days to replace the battery. In order to ensure the attendance rate and not affect the commuting of citizens, we need to allocate other vehicles to cover the shift, which has virtually increased the burden on enterprises. Micro macro's fast-rechargeable battery has no such problem. The battery power is almost the same as when it was first used since it was purchased last year. Song Cong said.

Song cong also mentioned a let him feel upset, lithium iron phosphate electric bus battery replacement, not once and for all to solve the problem, after more than a year of use, and serious battery attenuation phenomenon. "The life of a bus is eight years. Micro macro quick rechargeable batteries do not have this phenomenon. Economic advantages and operational advantages, which is the main reason why baojun bus only purchased micro macro quick rechargeable battery buses in the past two years. Song Cong said.

Song also mentioned that the electricity cost of weihong's fast-charging buses is lower than that of the first-generation slow-charging buses and slightly higher than that of the second-generation slow-charging buses. Daytime and nighttime electricity prices vary widely, and it is reasonable to say that the charge for a micro-macro fast-charging battery should be much higher than that for a slow-charging battery. However, there are not many passengers on buses outside the peak hours. Slow-charging buses run on tons of batteries, consuming electricity. Micro macro quick rechargeable battery weight hundreds of kilograms, the overall electricity charge down, micro macro quick rechargeable battery electricity charge is not much higher.

Since the micro macro quick rechargeable battery has obvious advantages, why not replace all the slow rechargeable buses? "Slow-charging buses can take advantage of peak and valley electricity prices and have certain economic advantages," song said. "" baojun bus will combine the advantages of both to comprehensively use new energy buses.

The truth of an old friend

After making up their minds to try quick charging, the leaders of baojun bus could not make up their minds about which company's products to choose. After all, they did not know much about new energy vehicles and had not used them before.

"Our country public transportation market is very big, but the public transportation circle is very small". This sentence vividly summarizes the current situation of China's public transport market, the leaders of public transport enterprises across the country know each other is not a few. Song cong first in the public transport circle to find out which use quick charge, foshan bus became his first station of investigation.

"Bus companies have regular meetings to exchange experiences," song said. We went to visit foshan bus company new energy car operation, they told the most real situation, let us eat the first reassuring.

In early 2014, siu lam bus terminal to buy 10 vehicles equipped with micro macro quick charge battery electric bus and 4 slow charging, comparing the dynamic bus after two years of operation, 10 vehicles equipped with micro macro quick charge battery electric bus charging time has changed little. 4 slow filling vehicles filled with original takes about an hour and a half, now more than two hours. After comparison and comprehensive cost calculation, xiaolan bus station is determined to use micro macro quick rechargeable battery buses. Today, more than half of the buses in xiaolan station are quick charge buses.

"After seeing the usage of one, we felt it was not enough. We went to huzhou bus company, whose usage was the same as xiaolan bus station." Song cong said, "after all, we are a private enterprise, I went to consult an old friend, he used to work in golden dragon bus for many years, very understanding of new energy vehicles, now left the automotive industry, I believe his opinion is more objective, more neutral.

This old friend told song cong, which product to choose depends on whether the enterprise has the core technology, the reliability of product quality, have the core technology that the enterprise is in the leading position, reliable quality to reduce the troubles in the operation. Micro macro has three core technologies leading the industry - non-combustion electrolyte, high temperature diaphragm, intelligent thermal control fluid (STL) passive defense technology. "All three technologies are aimed at battery safety," song said. Baojun bus is a private bus enterprises, burning a car not only social impact is large, the economic loss is quite large, more burned several, baojun bus can not afford the loss. Old friends tell me that battery safety accidents have never happened, and battery fires are one of the few enterprises in the world that never happen. "That statement reassured me.

Last year, baojun bus bought 100 micro macro quick rechargeable battery buses, and this year it bought 75 more. "Next, our goal is to maintain the number of slow charging and fast charging buses at 1:1." Song cong said finally.
