Technology
one system, from the fuse to the invoice
A charger is the easy part. What makes a site work is the layer above it: measuring the connection, switching phases, choosing the energy source, setting priorities, and billing every session. That layer is the same at a villa and at a truck depot.

The layers
Five layers, one operator
- 01
AC charger
VOOL 22 kW, all connectivity inside, patented phase switching.
- 02
Load controller
VOOL LMC at the grid connection: measures every 100 ms, sets the charging budget, switches phases.
- 03
DC charging
EVbee from 60 kW to 1.6 MW for fleets, trucks and hubs.
- 04
Battery storage and EMS
WattsFuture batteries from 107 kWh to 5 MWh and the EMS for grid, solar, chargers and markets.
- 05
Platform and app
Users, groups, tariffs, billing, reports, roaming; one view per site.
Intelligence
Four levels of intelligence
01
Building-level load management
The whole connection measured every 100 ms; chargers get what the building leaves.
02
Patented phase switching
Each charger on the phase with the most headroom: the full connection is usable.
03
Source of energy
Grid at market price, battery or solar, whichever is best now.
04
Priorities
Per user, per charger, per group and per time: fleet first, visitors last.
Made in Europe
Why one maker for charger, firmware and platform matters
01
No integration gaps
VOOL develops, engineers, patents and builds charger, controller, firmware, app and platform in Tallinn. A firmware change and a platform change ship together.
02
Efficient production
One 22 kW model with every option inside, assembled in Estonia: fewer variants, faster delivery, simpler spares.
03
Open where it counts
OCPP 1.6 and 2.0.1 to the outside; the platform manages other OCPP chargers too, so the site is never locked in.
