Battery replacing system of electric commercial vehicle

Abstract

The invention discloses an electric commercial vehicle battery replacing system, and the system comprises an electric commercial vehicle with a replaceable battery pack and a battery replacing 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 pile; the battery replacing trolley comprises a base provided with a walking mechanism and a lifting frame arranged on the base and driven by a lifting mechanism to ascend and descend, the lifting frame is provided with a frame rail matched with battery pack rolling wheels, and the frame rail is provided with a battery packpush-pull mechanism; the charging pile is provided with a pile track for the battery pack to slide, and a charging socket is arranged on the plugging panel at the end of the charging pile. 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, thebattery 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 power exchange 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 comprehensive promotion of e...

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
