FAQ
A nominal 7kW charger typically delivers up to 7.4kW from a single-phase supply; a 22kW AC charger requires three-phase power. The vehicle’s onboard AC charger also limits the charging rate, so a 22kW charge point will not charge every vehicle at 22kW. Sevadis offers MaxiCharger Gen2 7.4kW and 22kW options to match the supply, vehicle and parking time. More than 85% of British homes have a single phase supply, therefore a 7.4kW charger is recommended for residential scenarios, whilst 22kW is most suited to commercial & workplace environments.
Load balancing is recommended for installations with multiple EV chargers and is a crucial part of planning an EV charging site.
Even where a building or site has limited power available, load balancing can enable multiple EV chargers to operate by intelligently managing and distributing the available capacity across the charging network.
Power is optimised in real time based on factors such as the number of vehicles plugged in, their charging requirements and the building’s wider energy demand. As demand changes throughout the day, available power can be dynamically shared across connected vehicles, helping ensure charging is distributed efficiently and fairly.
This allows sites to support more EV chargers, maximise existing electrical capacity and reduce the need for costly power upgrades.
Sevadis recommends assessing the site supply, existing electrical demand, vehicle requirements and expected simultaneous usage to design the most effective load-balancing solution for each installation.
The MaxiCharger Smart AC Digital and LCD 22kW models are ideal for workplace, fleet and shared parking environments. Featuring charging insights, MID-certified metering on applicable models, RFID user authentication and open OCPP connectivity, the platform supports custom billing, user management, fleet charging and multi-site management through leading charge point management systems.
Dynamic load balancing, solar integration, PME fault detection and intelligent energy management further support safe and scalable commercial charging.
For long-stay employee and visitor parking, Sevadis recommends considering MaxiCharger Gen2 AC chargers, with 7.4kW or 22kW output matched to the supply and vehicles. Where vehicles need faster turnaround, consider Sevadis DC charging. The best business solution also includes suitable access control, billing and load management, so charging works alongside the building’s existing electrical demand.
The MaxiCharger Smart AC Digital and LCD range provides the connectivity and management functionality required for shared residential environments. Available in 7.4kW, 11kW and 22kW configurations, the platform supports RFID authentication, MID-certified metering on applicable models, OCPP connectivity, user management, billing integration and intelligent load management.
Dual and multi-charger mounting configurations also enable infrastructure to be designed efficiently around shared parking layouts.
Yes, a 22kW AC charger can be installed at a home with a suitable three-phase electricity supply, subject to an installer’s assessment. It also needs a vehicle capable of accepting that AC rate to deliver the expected benefit. Sevadis offers a MaxiCharger Gen2 22kW Digital Screen option. For homes with standard single-phase supplies, the 7.4kW range is the usual starting point.
SmartMesh is Sevadis’s Wi-SUN-based wireless networking and configuration approach for compatible chargers. Chargers form a site network that supports grouped configuration and settings cloning, reducing the need to configure each charger separately. It is a networking function rather than a standalone charger or billing platform. Confirm supported models, coverage and the required site internet connection during design.
Yes. Sevadis offers remote configuration and commissioning for compatible SmartMesh installations. The source material also describes an advanced workshop for commercial installers who need to configure systems themselves. Remote commissioning depends on the installed equipment being correctly connected and available for configuration. The installer remains responsible for the physical installation, testing and the required on-site verification.
SmartCloud enables compatible Autel chargers to connect with a chosen charge point management or back-office platform using open OCPP connectivity. Supporting OCPP versions from 1.6 through to 2.1 across compatible products and configurations, it provides the communication layer required for functions including remote charger management, billing, monitoring and fleet operation.
