Mitsubishi Motors trials NZ’s first-ever PHEV-to-home power transfer

  • PHEV market leader first in NZ to implement V2H
  • V2H allows power stored In EV batteries to be used by building networks
  • PHEVs now have more functionality than just a mode of transport

If you think of the family car as a machine that simply consumes power, think again! While it’s commonplace to power devices in our cars through a 12V plug, the technology for enabling electric vehicles (EVs) to provide power for our homes is just around the corner – and Mitsubishi Motors NZ (MMNZ) is leading the way.

In June, MMNZ became the first in New Zealand to install and operate a V2H (vehicle-tohouse) unit, which allows electricity stored in an EV’s battery to be supplied into a building’s power network.

The company had previously installed solar arrays on the roof of its HQ at Todd Park, Porirua to charge its fleet of Plug-in Hybrid EVs (PHEVs). By installing a Wallbox Quasar V2H module, MMNZ can now use the solar-generated charge stored in the PHEV batteries to power the electric hoists in its parts operation and other electrical appliances in the business.

MMNZ’s technical services manager Lloyd Robinson says the company has been keeping a close eye on the development of this cutting-edge technology for some time and, as the country’s largest seller of new PHEVs, it has been encouraging its Japanese parent Mitsubishi Motors Corporation to fast-track V2H in its cars.

“We have been aware that V2H modules would eventually land here and so have been able to ensure that all of our current generation Outlander and Eclipse Cross PHEVs, and our previous generation Outlander PHEVs, with CHAdeMO DC fast charge connections are V2H ready,” said Robinson.

While still in its infancy for NZ, the technology has the potential to provide stored energy resilience both to New Zealand’s power grid, by helping to buffer peak demand and in circumstances where properties may either lose connection to the grid or are permanently off the grid and have alternative sources of power generation (such as solar) to recharge the batteries.

Depending on the model, a Mitsubishi Outlander PHEV battery has a total power capacity of up to 20kWh, which is about the daily power consumption of an average Kiwi household with two adults and two children.*

“V2H is a really exciting development,” said Robinson. “And, while there are still some regulatory considerations to be worked through, I think we’ll start to see consumers looking at their cars in a whole new way.”

The V2H modules are compatible with standard single phase AC power supply common in New Zealand homes. Currently, V2H can only be active during normal operation of the power grid.

“The system can’t currently be used during a power outage, because there is no fool proof way to ensure the power from the battery doesn’t flow back into the grid and place electrical workers in danger,” said Robinson. “However, those types of hurdles will be overcome as uptake of the technology grows.

“The units themselves are also quite expensive – again, this will change as demand grows,” he said.

In the meantime, late model Mitsubishi PHEV owners, who charge their vehicles on night rates or via an alternative generation source, can now store that cheap power in their vehicle’s battery and pass it back into their homes or businesses when electricity prices are higher.

Wallbox distributor TransNet’s e-mobility division manager Glenn Inkster says: “Mitsubishi Motors NZ is the pioneer of V2H in New Zealand. Its PHEVs are among only a handful of NZ new models that currently have V2H capability. It is exciting times for this technology and we anticipate significant interest from PHEV owners. It really adds a new dimension to thinking about what EV to buy and the potential it has.”

While New Zealand focuses on transitioning more drivers to EVs – a process pioneered here by the Mitsubishi iMiEV in 2010 – Mitsubishi Motors New Zealand (MMNZ) is looking beyond EVs as just being a mode of transport.
