Which vehicles are compatible with Nuvve’s V2G?

Nuvve’s V2G software technology requires a pairing between a V2G charger (AC or DC) and a vehicle that has been enabled by its manufacturer for both charging and discharging energy from it. Nuvve is working closely with auto manufacturers and charger manufacturer companies to ensure this happens at the production level. Nuvve is also working with with auto manufacturers on R&D related to V2G.

Which electric buses are capable of V2G?

Currently the Blue Bird Vision (Type C) and Blue Bird All American (Type D) are V2G compatible. Additional products are planned for the future. Check with your bus manufacturer for the available models and upcoming launch dates.

What is the difference in power between AC and DC charging?

AC charging relies on an on-board charger inside an electric vehicle to charge the battery. For large school buses, the on-board charger is usually 19.2kW. In order to provide 19.2kW of power, it requires 80amps of capacity with 240V (80amps x 240volts = 19,200 watts). It’s still possible to charge a bus with lower voltage or a lower-rated charging station, but it will take longer to charge the bus.

DC charging can be a fast way to charge large electric vehicles such as electric school buses. The charging stations can be designed for different sized vehicles depending on their power ratings. Nuvve offers a 60kW DC option because it is a good balance of size, cost, and charge time for heavy-duty vehicles.

What is the difference between smart charging, V1G, V2B, and V2G?

Smart charging, sometimes called V1G, refers to the ability to dynamically modify the charge rate or the charge time. This can help minimize the cost of charging a vehicle if a rate schedule is based on time of use (TOU), such as middle of the night versus peak demand hours.

Vehicle-to-grid (V2G) refers to bidirectional energy flow between an electric vehicle’s battery and the charging station. Energy can be transferred to a building (vehicle-to-building or V2B) the charging station is connected to in order to manage energy costs, or can be sent to the grid (V2G) to earn revenue on energy markets. Similarly, if the building possesses excess energy from solar panels, this energy may be stored in the electric vehicle and re-used at a later time.

What are the installation requirements for V2G charging stations?

Nuvve has installation partners that provide a full turnkey solution or customers may opt to handle some aspects in-house.

Is the Nissan LEAF or the eNV200 V2G compatible with Nuvve’s PowerPort AC Level 2 charger?

No, the Nissan LEAF is capable of performing V2G only on a DC CHAdeMO port with a V2G DC charging station. However, the Nuvve PowerPort can be used for smart charging (V1G) with the Nissan LEAF.

How does this save money if I’m using the same amount of electricity?

By switching to a time-of-use (TOU) rate, we can ensure your vehicle is charged at the time when electricity is least expensive. Additionally, in certain cases, Nuvve will be “selling” the energy from the vehicle batteries back to the grid.

How do I operate the V2G features?

Nothing extra is required to take advantage of V2G with your vehicle charging. Nuvve simplifies the process by ensuring drivers always have the required energy to drive. The only requirement for the fleet operator is to set a schedule for what time the vehicles need to leave each day along with the total daily mileage required. Nuvve’s platform handles the rest.

Does V2G impact an electric vehicle’s battery?

No. Studies show that age of the battery and amount of driving have the biggest impact on the battery life. Many vehicle manufacturers, including electric bus manufacturers, have warranties that cover V2G operation based on studies that show V2G has little or negligible impact on battery health.

Do V2G charging stations need a different installation from non V2G charging stations?

No, the installation process is the same. However, an interconnection application with the electric utility is required to allow the electric vehicle batteries to discharge electricity to the building (V2B) or to the grid (V2G). Nuvve handles the interconnection application.

Can Nuvve’s DC charging station charge multiple vehicles at the same time.

Currently, Nuvve requires one 60kW charging station per heavy-duty vehicle in order to maximize the V2G value. And while Nuvve is working on this feature for future charging stations, shared DC charging is an expensive solution. A 60kW DC charging station shared among three vehicles will output 20kW per vehicle while a Level 2 AC charger can provide 19.2kW of power at a much lower cost.
