Electric vehicle conductive charging system - Part 23: DC electric vehicle charging station

IEC 61851-23:2014, together with IEC 61851-1:2010, gives the requirements for d.c. electric vehicle (EV) charging stations, herein also referred to as 'DC charger', for conductive connection to the vehicle, with an a.c. or d.c. input voltage up to 1 000 V a.c. and up to 1 500 V d.c. according to IEC 60038. It provides the general requirements for the control communication between a d.c. EV charging station and an EV. The requirements for digital communication between d.c. EV charging station and electric vehicle for control of d.c. charging are defined in IEC 61851-24.

Elle fournit les exigences générales relatives à la communication de contrôle entre borne de charge à courant continu pour véhicule électrique et un véhicule électrique. Les exigences relatives à la communication digitale entre la borne de charge à courant continu pour véhicule électrique et le véhicule électrique en vue du contrôle de la charge à courant continu sont définies dans l'IEC 61851-24.

Sistem kabelskega napajanja električnih vozil - 23. del: Postaja za kabelsko napajanje električnega vozila z enosmernim tokom (IEC 61851-23:2014)

Standard EN IEC 61851-23 skupaj s standardom IEC 61851-1:2010 podaja zahteve za postaje za kabelsko napajanje električnega vozila (EV) z enosmernim tokom, v nadaljevanju tudi »polnilnik DC«, za prevodno povezavo do vozila z izmenično (a.c.) ali enosmerno (d.c.) vhodno napetostjo do 1000 V a.c. in do 1500 V d.c. v skladu s standardom IEC 60038. Ta del zajema enosmerne izhodne napetosti do 1500 V. Zahteve za dvosmerni tok energije so v obravnavi. OPOMBA 2 Običajni diagrami in različice napajalnih sistemov z izmeničnim tokom so prikazani v Prilogi DD. Ta standard ne zajema vseh varnostnih vidikov, povezanih z vzdrževanjem. Ta del določa polnilne sisteme z izmeničnim tokom A, B in C, kot je določeno v Prilogah AA, BB in CC. Zahteve elektromagnetne združljivosti za polnilne postaje za električna vozila z enosmernim tokom so določene v standardu IEC 61851-21-2. Ta standard določa splošne zahteve za nadzorno komunikacijo med polnilno postajo za električna vozila z enosmernim tokom in električnim vozilom. Zahteve za digitalno komunikacijo med polnilno postajo za električna vozila z enosmernim tokom in električnim vozilom za nadzor polnjenja z enosmernim tokom so določene s standardom IEC 61851-24.
