Efficient battery replacing system of electric commercial vehicle

Abstract

The invention discloses an efficient battery replacing system for an electric commercial vehicle, and the system comprises the electric commercial vehicle with a replaceable battery pack and a batteryreplacing station. The system is characterized in that a transverse battery bin is arranged at the bottom of a girder of the electric commercial vehicle, a bin door is arranged at one end of the girder, and a connecting socket butted with a battery pack plug is arranged on the other end wall opposite to the bin door; an in-bin track is arranged in the battery bin and is matched with a battery pack roller; the battery replacing station comprises a battery replacing trolley and a charging room, the battery replacing trolley is provided with a frame track matched with the battery pack rollers, and the frame track is provided with a battery pack push-pull mechanism; a charging floor stand is arranged in the charging room, cells are arranged on the charging floor stand in an array mode, charging piles for charging battery packs are arranged in the cells, and a battery replacing trolley conveying mechanism for conveying battery replacing trolleys to the charging piles is further arranged. The specification standardization of the battery packs of the electric commercial vehicles with different tonnages is realized, the battery packs are replaced by the same set of battery replacing equipment, the battery replacing efficiency is high, the cost is extremely low, the popularization is easy, and the problem that the electric commercial vehicles cannot be popularized is thoroughly solved.

Description

technical field [0001] The invention relates to a high-efficiency battery swapping system for an electric commercial vehicle. Background technique [0002] Automobile oil-to-electricity conversion is a major strategic policy for the country to reduce a large amount of oil imports, and an important national policy for energy conservation, emission reduction, and green development. Compared with traditional cars, electric vehicles can achieve zero emissions during driving, and have low noise, and the driving cost is much lower than that of traditional cars. Through years of hard work, the oil-to-electricity transformation of buses in my country has been steadily advanced, and small electric household vehicles have also developed rapidly. [0003] Although the country has issued a number of supporting policies for electric vehicles, and electric vehicles have many advantages, electric vehicles still cannot be fully promoted. The fundamental reason that restricts the comprehens...

Problems solved by technology

The problem of charging mode: According to the current battery technology, it takes 2 hours to fully charge the battery under the premise of ensuring battery life. This is also the most fundamental problem that electric vehicles cannot replace fuel vehicles; There are many problems such as large differences, complex and expensive power replacement equipment, and inconsistent specifications, so they cannot be widely used

[0006] 1) Based on the existing battery technology, taking into account factors such as the weight, volume, and price of the battery, the fully charged mileage of the battery that is reasonably configured for the current electric commercial vehicle is about 300km-400km. If each charge takes two hours for transportation Vehicles are unacceptable to the freight industry

[0007] 2) It takes a long time to use a charging pile to directly charge the vehicle battery pack, and it takes a long time to occupy a parking space. As we all know, the space occupied by commercial vehicles is much larger than that of ordinary household small cars, and it is difficult to build a large number of charging stations like household small cars. popularization, making it difficult to realize the charging demand of electric commercial vehicles

Therefore, it is impossible to promote and popularize
