Vector Set to Unleash Power of EVS via Two-Way Charging
In yet another innovative first, Vector is introducing a two-way electric vehicle (EV) charger that will transform EVs into mobile power sources for businesses and homes. It is also announcing of 4 new public EV
charging locations in Auckland over the next two months to cater to growing demand.
The new vehicle-to-grid (V2G) EV charger will facilitate energy flow both to and from an EV, allowing it to act as a
rechargeable energy source. When hooked up to a V2G charger at home or work, charge from an EV can be used as a power
boost for the building, as a cheaper power source when electricity prices are at their peak, and will eventually be able
to power homes during power outages.
With a Nissan Leaf G2 carrying 30kW battery power for example, and the average household using about 3kW an hour, EVs
can be a great energy source. Chief Networks Officer, Andre Botha, says the technology trialled on Vector’s nearly 100
per cent EV fleet will soon be offered to New Zealand businesses and households.
“We are totally committed to providing innovative, state-of-the-art energy solutions, investing in public EV
infrastructure and expanding our network to meet the needs of a fast-growing Auckland,” says Mr Botha.
“Vector is giving people new opportunities and choices in how they use and manage their energy needs. V2G technology
takes EVs to another level, making them an integral part of the home environment. As well as providing backup power when
needed, it gives people greater flexibility and an alternative to using energy from the grid,” he said.
Vector recognises that with ‘time of use’ pricing and energy trading systems on the horizon, the decisions about when a
consumer buys energy – and who they choose to buy it from – become much more important. For example, someone with solar
panels might charge an EV at home when there is ample sunlight and then use the EV to power their home during peak
periods when prices are higher.
“On the network, it will help smooth out the growing impact EVs have on our peak electricity demand. The numbers of EVs
registered in NZ continues to grow and when all of them are plugging in at the same time after work to charge, it
presents an interesting challenge which we have turned into an opportunity.
“With V2G technology, many homes could be powered by their EVs at peak time. Similarly, EVs will be releasing energy
back to the grid to support grid demand while taking advantage of a higher peak energy buyback rate.
“When you add solar and battery systems into the mix, along with emerging home energy management systems, you’ve got a
truly smart energy home. It’s part of the new energy future we’ve been driving that gives people more choice, control
and affordability than ever before,” Mr Botha said.
Vector has confirmed 7 new EV chargers in 4 Auckland locations over the next two months with more to come. The new
locations are Kumeu New World, BP Warkworth, Auckland Hospital, and Constellation Drive McDonalds.
