What is a smart EV charging tariff?
A smart EV charging tariff is an electricity pricing arrangement designed to make charging more attractive at particular times or under specific conditions.
Some tariffs offer different electricity rates at different times of day. Others may use more complex pricing structures or require compatible smart charging technology.
By coordinating charging with the applicable tariff, drivers and businesses may be able to reduce electricity costs.
How do time-of-use tariffs work?
A time-of-use tariff charges different rates during different periods.
For example, electricity may cost less overnight than during an evening peak. A driver with a vehicle parked overnight could schedule charging for the lower-priced period, provided the vehicle is ready when needed.
However, tariff structures vary by supplier and contract. Businesses should review the complete pricing terms rather than assume that every overnight period is cheaper.
What role does smart charging play?
Smart charging can adjust when or how quickly a vehicle charges based on supported inputs, including tariff information and charging requirements.
For fleets, this can help coordinate multiple vehicles rather than having every charger draw maximum power simultaneously.
Potential savings depend on the tariff, vehicle availability, charging behaviour, site constraints and any additional fees. A cheaper unit rate does not automatically mean a lower total electricity bill.
What should drivers and businesses check?
Before choosing a tariff, review the unit rates, peak periods, standing charges, eligibility requirements and any compatible charger or vehicle requirements.
Businesses should also consider whether their electricity contract includes demand-related charges and whether shifting charging could affect operations.

Frequently asked questions
Is overnight EV charging always cheaper?
No. It depends on the tariff and the time at which charging takes place.
Does a smart tariff require a smart charger?
Requirements vary by supplier and tariff. Some arrangements require compatible equipment or software, while others offer different ways to schedule charging.
Can businesses use smart tariffs for fleets?
Potentially. Suitability depends on the electricity contract, fleet schedules and charging infrastructure.
