Electric vehicle conductive charging system - Part 3-2: DC EV supply equipment where protection relies on double or reinforced insulation - Particular requirements for portable and mobile equipment

This part of IEC 61851-3 series (in a first step as Technical Specification for three-year period) together with part 1 of IEC61851-3, applies to the d.c. power supply equipment (e.g. VCU) for the conductive transfer of electric power between the supply network and an light electric road vehicle when connected to the supply network , with a rated supply voltage up to 480 V a.c. or up to 400 V d.c. and a rated ìoutputî voltage up to 480 V a.c. or up to 200 V d.c. The supply systems described in the IEC 61851-3 series are primarily intended for the use by EVs of category L hereinafter referred to as light electric vehicles (light EVs). NOTE 1 Light EV includes all electrically propelled two and three wheeled vehicles of Category L1 up to Category L7 according to the definition of ECE-TRANS-WP29-78r2e and all electrically propelled or assisted cycles. The electrical protection of the complete light EV supply system from the connection to the supply network up to the light EV or removed RESS complies with protective separation and with galvanic separation between a.c. input and d.c. output or class III.

Système de charge conductive pour véhicules électriques - Partie 3-2 : Exigences relatives aux véhicules électriques légers - Matériel de charge conductive en courant continu

Sistemi za napajanje električnih vozil - 3-2. del: Oprema za napajanje električnih vozil z enosmernim tokom, kjer varnost zagotavlja dvojna ali ojačena izolacija - Posebne zahteve za prenosno in mobilno opremo (IEC/TS 61851-3-2:2023)

Ta del skupine standardov IEC 61851-3 (v prvem koraku kot tehnične specifikacije za triletno obdobje) skupaj s 1. delom standarda IEC 61851-3 se uporablja za opremo za napajanje z enosmernim tokom (npr. VCU) za konduktivni prenos električne energije med električnim omrežjem in lahkim električnim cestnim vozilom, ko je to priključeno na električno omrežje z nazivno izmenično napetostjo napajanja do 480 V ali enosmerno napetostjo do 400 V in nazivno izhodno izmenično napetostjo do 480 V oziroma izhodno enosmerno napetostjo do 200 V.
Napajalni sistemi, opisani v skupini standardov IEC 61851-3, so namenjeni predvsem uporabi električnih vozil kategorije L, v nadaljevanju lahka električna vozila.
OPOMBA 1: Lahko električno vozilo pomeni vsa dvo- in trikolesna vozila na električni pogon kategorij L1 do vključno L7 v skladu z definicijo ECE-TRANS-WP29-78r2e in vsa kolesa na električni pogon in kolesa s pomožnim motorjem.
Električna zaščita celotnega napajalnega sistema lahkega električnega vozila od priključka na električno omrežje do lahkega električnega vozila ali odstranjenega sistema za shranjevanja energije z možnostjo ponovnega polnjenja je skladna z zaščitno ločitvijo in z galvansko ločitvijo med vhodnim izmeničnim tokom in izhodnim enosmernim tokom oziroma opremo razreda III.
