Electric vehicle (EV) charging is part of the drive to net-zero, however the decarbonisation of transport using EVs requires the management of electricity end-use in a way that is beneficial to the electricity supply system for stability, reliability, efficiency and lower infrastructure cost.
EV charging is now part of the built environment and has a significant impact on electrical loads and consumption patterns. It also significantly impacts peak electrical load, tariff choice and the selection of renewables / fixed batteries.
The charge rate of EV batteries is dependent on the battery state of charge (SoC), so charging rate typically drops as an EV battery is charged. Thus, simple profiles (like those used for VE miscellaneous loads) do not adequately describe EV charging, and the creation of more realistic profiles is time consuming as each instance is bespoke.
The VE EV charging feature has been introduced to provide a rapid tool for users to generate realistic EV charging profiles for use in models; profiles created are based on a battery charging curve, battery size, charge limits, charger setup and charging site / multiple usage.
The VE EV charging feature adds EV charging loads at the building level (assignable to meters) with dedicated auto-generated editable free-form variation profiles.
