GB/T 43657.1-2024 Energy efficiency of industrial trucks - Test methods - Part 1: General
1 Scope
This document specifies general test criteria and requirements to measure the energy consumption for self‑propelled industrial trucks (hereinafter referred to as “trucks”) during operation. For electric trucks, the efficiency of the battery and the battery charger is included.
The truck specific requirements in ISO 23308‑2 and ISO 23308‑3 take precedence over the respective requirements of this document.
This document is applicable to the in‑use phase of the product life cycle.
It applies to the following truck types according to ISO 5053‑1:
——counterbalance lift truck;
——articulated counterbalance lift truck;
——reach truck (with retractable mast or fork arm carriage);
——straddle truck;
——pallet‑stacking truck;
——pallet truck;
——platform and stillage truck;
——pallet truck end controlled;
——order‑picking truck;
——centre‑controlled order‑picking truck;
——towing, pushing tractor and burden carrier;
——towing and stacking tractor;
——side‑loading truck (one side only);
——variable‑reach container handler;
——counterbalance container handler;
——lateral‑stacking truck (both sides);
——lateral‑stacking truck (three sides);
——multi‑directional lift truck.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO 5053-1 and the following apply.
3.1
battery
electrical power source consisting of battery cells, connectors of cells, battery controller (if applicable, e.g. controller for Li-Ion batteries) and battery enclosure that is ready to use in a truck
3.2
battery state of charge
measured capacity (in Ampere hours [A·h]) of the battery divided by the maximum rated capacity [A·h], expressed as a percentage
3.3
carbon dioxide equivalent; CDE
quantity that describes, for a given mixture and amount of greenhouse gas, the amount of CO2 that would have the same global warming potential (GWP)
3.4
charging factor
ratio between amount of [A·h] recharged into the battery and the prior discharged amount of [A·h] from the battery
Note 1 to entry: Typically, the charge factor for lead acid batteries is in the range of 1.02 to 1.25.
3.5
power battery factor; PBF
factor that gives the ratio between the battery capacity and the electrical power taken from the battery
3.6
synthetic discharge cycle
typical battery discharge profile that mirrors the actual energy consumption of electric trucks during a test cycle
