Breakthrough New Energy Chongqing Bus Demonstration First

Recently, the first charging and switching station in Chongqing was completed and put into operation in the Weibei Airport area, and the second batch of 25 Hengtong fast-charged pure electric buses was put into operation. This marked the construction of Chongqing electric vehicle charging and replacing facilities. The operation has taken a new step and undoubtedly promoted the rapid development of Hengtong Electric Bus.

At the same time as the demonstration operation, Hengtong Company frankly stated that the current fast-charge model still has problems such as low energy and delayed charging station construction. In order to solve these problems, Hengtong plans to use another three years or so to check the reliability of fast-charged batteries and “halve” the cost to reach the level of lithium iron phosphate batteries. At the same time, she also plans to adjust the ratio of her pure electric and plug-in electric buses based on the construction speed of the charging station.

As we all know, the fast charge mode is completely different from the slow charge mode that is currently on the market.

It uses a new lithium titanate battery. The battery system is manufactured by Chongqing Hengtong Electric Bus Power System Co., Ltd. (hereinafter referred to as Hengtong Electric Company), a joint venture between Micro-Power (Huzhou) Co., Ltd. and Hengtong Bus. It can be manufactured in as little as 10 minutes. After being fully charged, it is several times more efficient than traditional electric buses that take 4-6 hours to charge. Due to the rapid charging method, the battery pack can be greatly reduced in the bicycle, and the economic benefit is good. The bus company recovery cost is relatively fast.

It is understood that in order to verify the performance of fast-charging public transport buses, Hengtong Bus and Chongqing Public Transport have started demonstration operations since the first half of last year. Hengtong’s idea is to use Chongqing Bus as an experimental base to verify whether the cycle life of lithium titanate batteries can really satisfy 20,000 decays. As long as the actual operation can reach 15,000 times, it can be inferred that the battery life can reach 8 years, so as to truly break the bottleneck of the current short-lived lithium phosphate battery life. So far, on the basis of the 25 vehicles put on April 27, there are 31 fast-charging electric buses actually operating on the bus lines in Chongqing. Among them, the first six vehicles were put into operation on the 609 line in Chongqing in April 2011. This vehicle has so far traveled nearly 50,000 kilometers.

However, the actual operation needs to bear great risks. According to the price of RMB 1.6 million per vehicle, it is several hundred million yuan to put large batches of fast-moving buses into operation. This is not a small number for most companies. It also makes any bus company unwilling to take risks. Why Chongqing Bus is willing to take such a big risk?

The reporter learned that Hengtong Bus is a subsidiary company of Chongqing Bus Group. Chongqing Bus hopes to make electric bus bigger and stronger through Hengtong bus and promote the smooth implementation of Hengtong's breakthrough strategy for new energy bus.

“This is also a socially responsible performance. The idea of ​​selling it first and then speaking is impossible. We cannot bring immature products to market.” Tian Ye, executive vice president of Hengtong Electric Company, was interviewed by the reporter of the first commercial vehicle network. Said. He told reporters that after one year of actual operation, the number of charging times for fast charging buses is more than 2,000 times a year, and the battery capacity has not been attenuated, and the operation results are good.

Oil Field Nitrogen Generator

Gamma oil field Nitrogen Generator is good for oil exploitation, it is supplied by Shandong Gama Gas Engineering Co.Ltd, it has big flow rate, 5-3000 Nm3/hr, 250 bars/ 3626 psi high pressure. It is widely used for second and third stage oil exploitation, increasing oil production ratio.

For oil exploitation, after the first stage production, the maintained oil is difficult to come out with traditional method. Using high pressure big flow rate nitrogen to push the oil field, is a good way to push out the oil. Oil feild nitrogen generator is suitable for wild application, all parts included in one cabinet. After connecting electricity, high pressure nitrogen is produced.
