Smart charging technology - how does it work?
Smart Charging is an umbrella term that defines all intelligent functionalities in EVBox’s charging stations that optimize the charging infrastructure by creating and distributing the available power in an efficient and flexible manner. With Smart Charging, not only would you avoid unnecessary costs such as overcapacity fees, but you’ll also get the most out of your charging stations in case of limited power capacity, anytime, any place.
Load Balancing is an indispensable Smart Charging feature for those that operate a charging station with dual sockets or multiple charging stations at a specific location.
Operating a charging station requires your power source (e.g. office building) to carry the cumulative sum of the total capacity of these charging stations. Load Balancing distributes the available capacity proportionally over all active charging stations. In doing so, Load Balancing ensures that optimal charging is provided to all-electric vehicles at your location, within the limits of your charging stations’ capacity.
Your building (power source) has a maximum of 25A available. At your building’s parking lot, you own a BusinessLine Charging Station with dual sockets that have a maximum of 32A available. When the first car charges at your charging station, this is done at 25A, the maximum capacity that your building allows. As soon as a second car starts charging, the charging capacity will be distributed proportionally over these two cars. Both cars will now charge at 12,5A.
Hub / Satellite
Hub / Satellite is an indispensable Smart Charging feature for those who wish to operate multiple charging stations at a single location.
To save you time and effort, EVBox not only takes care of automatic settlements of charging transactions, it also conveniently gathers the data coming from all of your charging stations within a single cloud-based management platform: BackOffice.
To function properly, BackOffice needs each charging station to communicate data to its system. This is where a Hub / Satellite configuration comes in handy. Instead of having each charging station communicating data individually – which would require each station to have its own built-in modem, Hub / Satellite enables up to 20 charging stations to communicate through a single modem.
This configuration saves you from unnecessary maintenance and multiple subscription plan costs. After all, there’s only a single modem to be fixed in any rare cases of malfunction, and there’s only one BackOffice subscription plan necessary to generate and manage data.
You have installed 3 BusinessLine Charging Stations with dual sockets at your parking facility. One of these three charging stations is the Hub station, to which all other stations (Satellites) are connected through a cable that runs underground. This cable enables each Satellite station to send its data to the Hub Station. The Hub station gathers all data and sends it to BackOffice. The BackOffice processes the data and creates essential insights into your charging sessions at all three stations.
During each charging session, your power consumption may run up to the maximum capacity available. This means that you will have to be careful when you switch on the washer or dryer. When you exceed your maximum capacity your network operator will charge you retrospectively for that. Peak Shaving helps to prevent this. As soon as you threaten to reach maximum capacity, EVBox will automatically reduce the consumption of a charging session, or even pause the sessions altogether until enough power becomes available.
