According to the analysis of the applicable scenarios of heavy truck powertrain, pure electric trucks are relatively suitable for short-distance logistics, mining, factory and terminal transportation in the city. To further meet the multiple needs of the market and users, it gradually develops in the direction of multi-gear, high speed and low torque. New energy special vehicles have the characteristics of relatively fixed driving distance, driving mileage focusing on short and medium distance, convenient centralized charging, etc. As an automotive product supplier, we can provide innovative electrification products and technical solutions to meet the growing needs of the market.
Mainstream High-voltage Electronic Control Requirements For New Energy Electric Trucks
In terms of the current electric heavy truck drive assembly mode architecture, mainly coaxial single-motor central drive, electric drive bridge is also gradually developed, multiple routes go hand in hand. Considering the cost, efficiency, dynamics, technical complexity and other factors, the future based on multi-gear route, low torque, high speed dual-motor central drive and single-motor dual-axle will be the mainstream direction. We always take miniaturization and low cost as the development goal from the perspective of end users and OEMs, and at the same time do a good job of high conversion efficiency and lightweight, to reduce the cost of the whole vehicle for customers and improve the driving experience of users.
