Abstract

The invention discloses a towing-type vehicle and a trailer. The towing-type vehicle comprises a towing vehicle, the trailer and a vehicle controller; the towing vehicle comprises a first energy storage system; the trailer comprises a second energy storage system which is suitable for being connected with the first energy storage system and the vehicle controller under a towing mode; and under thetowing mode, the energy supply level of the second energy storage system is higher than the energy supply level of the first energy storage system. According to the towing-type trailer, a power battery system with the same high and low voltage parameters as the energy storage systems (such as a power battery system and a hydrogen fuel storage device) of the towing vehicle can be integrated on thetrailer, the driving mileage under the towing condition is increased, the operation efficiency under the trailer-free working condition is improved, and the energy utilization rate is increased, wherein the high and low voltage parameters comprise the voltage or gas pressure, communication and control strategies and the like.

Description

technical field [0001] The invention relates to the field of vehicle manufacturing, in particular to tractor vehicles and trailers. Background technique [0002] In the related art, the power battery system of the pure electric semi-trailer tractor vehicle is all installed on the tractor, so the driving range is short and the energy consumption efficiency is low. There are two forms of range-extended vehicle technology, one is oil-electric hybrid extended-range technology, which uses fuel as fuel to mix internal combustion engines with power battery systems; the other is electric-electric hybrid extended-range technology, which uses fuel cell systems and power Hybrid battery system. Moreover, when supplying energy, the power battery is used as the main power output, and the internal combustion engine system or fuel cell system is used as the power battery to provide energy supply to achieve the effect of range extension. Both of the above two energy storage systems are fix...
