What is BS EN 61851-23 - DC electric vehicle charging station about?
BS EN 61851 is a European Standard on electric vehicle conductive charging systems. The main purpose of the BS EN 61851 series is to ensure faster and on-demand charging and robust connectivity to support electric vehicles’ current and future needs.
BS EN 61851-23 is the 23rd part of the BS EN 61851 series that 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.
BS EN 61851-23 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 is defined in IEC 61851-24.
Requirements for bi-directional power flow are under consideration.
EMC requirements for d.c. EV charging stations are defined in IEC 61851-21-2.
Note: BS EN 61851-23 does not cover all safety aspects related to maintenance.
Who is BS EN 61851-23 - DC electric vehicle charging station for?
BS EN 61851-23 on DC electric vehicle charging station is useful for:
- EV designers and manufacturers
- Electrical and mechanical engineers
- EV charging stations units
- Electronic equipment and components manufacturers and suppliers
- Designers of vehicle batteries
- Vehicle regulatory authorities
Why should you use BS EN 61851-23 - DC electric vehicle charging station?
The introduction and commercialisation of electric vehicles have been accelerated in the global market, responding to the global concerns on CO2 reduction and energy security.
Concurrently, the development of charging infrastructure for electric vehicles has also been expanding. As a complement to the a.c. the charging system, d.c. charging is recognized as an effective solution to extend the available range of electric vehicles.
In this regard, BS EN 61851-23 is developed for the manufacturers’ convenience by providing general and basic requirements for d.c. EV charging stations for conductive connection to the vehicle.
BS EN 61851-23 specifies the rating of the supply a.c. voltage, protection against electric shock, specific requirements for vehicle coupler and charging cable assembly requirements.
As a result, DC charging usually allows for much faster charging and quickly recharge during long-distance trips. DC electric car charging stations can be the ideal solution for EV companies due to its ability to charge faster and ultimately can serve more drivers in a day.
