A number of government ministries are working on regulations which would impose a "charging tax" on electrical vehicles based on the time of charging, to prevent too much strain on the electrical grid as a whole, per Globes.
The tax is currently in the pilot phase and would depend on electrical vehicles reaching a "critical mass" of vehicles on the road. The tax would be calculated based on "smart" home and public chargers, much like "smart" home meters today.
On the other hand, the Energy Ministry said that the government had decided on a travel tax rather than a charging tax to reduce the burden on traffic in rush hour and on the electrical grid during peak usage.
