[Background]

It is necessary to measure the low-temperature single-charge driving range of electric buses starting in '26. Therefore, chassis dynamometer test methods need to be established.

[Main Points]

o (Test Method) Establishing chassis dynamometer test conditions for measuring the single-charge range of large electric passenger vehicles.

(Driving Mode) Applying a multi-mode mixing city, suburban, and constant speed.

o (Excluded Vehicles) Excluding articulated and double-decker buses where testing is impossible.
