Charge RosterFree workplace charging tool
Do you need more EV chargers — or better use of the ones you already have?
Estimate the charging time your employees need, compare it with the charger-hours already available and diagnose whether the next problem is coordination, physical capacity or electrical infrastructure.
What the numbers suggest
Charging demand / day20.0 h
Available charger-hours / day36.0 h
Required share of charger-hours56%
EV drivers per charger5.0
Projected charger-hours after growth30.0 h
If the charger-hours fit, make the available time easier to share.
Charge Roster gives employees one shared schedule for the workplace chargers already installed.

This is an operational planning tool. It compares the charging time employees need with the charging time your existing chargers can offer during the working day.
- Daily charging demand = drivers needing a charge × average charging time.
- Available charger-hours = chargers × bookable hours per charger.
It does not size electrical supply, model charging power, battery state of charge or dynamic load management. Use qualified infrastructure specialists for those questions.
