IEC 62282-4-102:2022 specifies the performance test methods of fuel cell power systems for propulsion and auxiliary power units (APU). This document covers fuel cell power systems for propulsion other than those for road vehicles. This document applies to gaseous hydrogen-fuelled fuel cell power systems and direct methanol fuel cell power systems for electrically powered industrial trucks. The following fuels are considered within the scope of this document: - gaseous hydrogen, and - methanol. This document covers the fuel cell power system as defined in 3.7 and Figure 1. This document applies to DC type fuel cell power systems, with a rated output voltage not exceeding DC 150 V for indoor and outdoor use. This document covers fuel cell power systems whose fuel source container is permanently attached to either the industrial truck or the fuel cell power system. This second edition cancels and replaces the first edition published in 2017. This edition includes the following significant technical changes with respect to the previous edition: a. alignment of the Scope with the second edition of IEC 62282-4-101:2022; b. deletion of terms and definitions (previous entries 3.5, 3.10, and 3.15); c. addition of new terms in Clause 3: "delivered power" (3.13) and "regenerated power" (3.14); d. revision of symbols and their meanings in alignment with those of IEC 62282-3-201; e. replacement of "reference conditions" with "standard conditions" as seen in Clause 5; f. revision of the test method for the accessory load voltage spike test (13.3.2); g. addition of clarifications in Clause 14 (Power stability under operation); h. addition of a checklist for performance criteria dealt with in this document (Annex C). LIEC 62282-4-102:2022 specifie les methodes d’essai des performances des systemes a piles a combustible pour la propulsion et les groupes auxiliaires de puissance (GAP). Le present document couvre les systemes a piles a combustible destines a la propulsion, autres que ceux destines aux vehicules routiers. Le present document s’applique aux systemes a piles a combustible utilisant de l’hydrogene gazeux et a ceux utilisant du methanol direct pour les chariots de manutention electriques. Les combustibles suivants relevent du domaine d’application du present document: - hydrogene gazeux; et - methanol. Le present document traite du systeme a pile a combustible defini en 3.7 et a la Figure 1. Le present document s’applique aux systemes a piles a combustible de type a courant continu, d’une tension de sortie assignee maximale de 150 V en courant continu pour utilisation a l’interieur et a l’exterieur. Le present document concerne les systemes a piles a combustible dont le conteneur de source de combustible est fixe a demeure, soit au chariot de manutention, soit au systeme a pile a combustible. Cette deuxieme edition annule et remplace la premiere edition parue en 2017. Cette edition inclut les modifications techniques majeures suivantes par rapport a l’edition precedente: a. alignement du domaine d’application sur la deuxieme edition de l’IEC 62282­4­101:2022; b. suppression de termes et de definitions (les entrees 3.5, 3.10 et 3.15 qui existaient precedemment); c. ajout de nouveaux termes a l’Article 3: "puissance fournie" (3.13) et "puissance regeneree" (3.14); d. revision de symboles et de leurs significations en vue d’un alignement sur ceux de l’IEC 62282-3-201; e. remplacement de "conditions de reference" par "conditions normales" comme vu a l’Article 5; f. revision de la methode d’essai pour l’essai de pointe de tension des charges accessoires (13.3.2); g. ajout de clarifications a l’Article 14 (Stabilite de la puissance en fonctionnement); h. ajout d’une liste de controle pour les criteres de performance traites dans le present document (Annexe C).
