Earthmoving machinery electric wheel loader
Energy consumption test method
1 Scope
This document specifies the test conditions for the energy consumption of pure electric wheel loaders and describes the measurement method and test method of energy consumption.
Methods, as well as methods for evaluating energy consumption and endurance.
This document applies to aircraft using onboard power batteries (maximum operating voltage is Class B voltage) as the only power source during operation, with a rated
The energy consumption test of pure electric wheel loaders with a working load not exceeding 8 000 kg uses other types of rechargeable energy storage devices,
For reference use, electric loaders with a rated working load greater than 8 000 kg.
