All-electric vehicle tractor

Abstract

The invention discloses an all-electric vehicle tractor. The all-electric vehicle tractor comprises a power supply system which supplies power to a power system of the tractor, wherein the tractor power supply system comprises a first traction battery pack and a second traction battery pack; the first traction battery pack and the second traction battery pack are respectively connected with the power supply control system; a trailer power supply system comprises a trailer battery pack arranged on a trailer frame, and the trailer battery pack is electrically connected with the power system of the tractor and is in signal connection with the power supply control system. According to the all-electric vehicle tractor, through reasonable design of the battery power supply system, the tractor can be connected with the battery system on the dragged vehicle, the battery system on the dragged vehicle is used for providing driving force for walking of the tractor, the endurance mileage of the tractor is prolonged, the battery charging time of the tractor is shortened, and the working efficiency of the tractor is improved.

Description

Technical field [0001] The invention belongs to the field of tractors, and more specifically relates to an all-electric vehicle tractor. Background technique [0002] Electric tractors are driven by motors and are used for short-distance horizontal transportation of goods in regional yards such as ports. Materials are often stored in trailers, and tractors are required to solve the efficient transportation of materials in different sections. At present, when enterprises use electric tractors to provide power, because the tractors are operating in the terminal, the tractors are required to continue to operate due to the requirements of the operating conditions, and they will frequently start without load, heavy load, accelerate, emergency stop, and long time. Standby waiting for work, working status is diverse and complicated. [0003] Traditional electric tractors have insufficient battery installation space, limited battery configuration capacity, limited working range and workin...

AI Technical Summary

Problems solved by technology

At present, when enterprises use electric tractors to provide power with electric energy, because the tractors are operating at the wharf, due to the requirements of the working conditions, the tractors are required to continue to work, and they will frequently start with no load, heavy loads, acceleration, emergency stops, and long-term Standby and waiting for jobs, the working status is diverse and complex

[0003] The battery installation space of traditional electric tractors is insufficient, the battery configuration capacity is limited, the working mileage and working time are limited, and it cannot meet the continuous operation requirements of electric tractors. , affecting work efficiency

Furthermore, the overall structure of the tractor is compact, the battery installation location is highly concentrated, the heat dissipation air duct of the battery itself is limited, and the heat of the battery during operation cannot be discharged in time, which is prone to rapid temperature rise and affects the battery life.

If a large number of batteries are arranged on the body of the tractor, it will also increase the weight of the vehicle, affect the power performance of the tractor, and pose a safety hazard
