FREQUENTLY ASKED QUESTIONS

What's the difference between fuel cell, electric battery and plug-in hydbrid vehicle?

All three vehicles use electric traction motors, to provide drive to the wheels but there are differences as to the power source used to provide electricity to the traction motor is supplied. 

For Fuel-cell Electric Vehicles (FCEV) hydrogen gas from the vehicles on-board hydrogen tanks and oxygen from the air is supplied to what is called a Fuel Cell Stack (located in the engine bay), an electrochemical reaction takes place inside the Fuel Cell Stack and this reaction generates electricity to provide electrical power to the traction motor.  

A Battery Electric Vehicle (BEV) gets its electricity to power the traction motor entirely from Lithium-ion batteries, which can be re-charged using three methods. (charging times for each method do vary)

  • AC Slow – standard NZ 3-pin (8Amp) portable electric charger
  • AC Fast – wall mounted single phase 7.4kW charger (recommended for home charging)
  • DC Rapid – national infrastructure       

Plug-in hybrids (PHEV) have a Lithium-ion battery (about 1/3 of the size of the IONIQ BEV) and only two charging methods are possible (AC Slow & AC Fast). With PHEV’s you can drive in EV Mode (all-electric mode) for up to 63km* and then the vehicles 1.6L petrol engine will take over. You can also drive using both sources of power (battery & engine).

Hybrids (HEV) have even a smaller Lithium-ion battery (1.56KWh) and the only way this battery is recharged is by the vehicles 1.6L petrol engine.

*Energy & Fuel consumption figures are based on ADR 81/02 tests and factory information. These figures are provided to assist you in comparing the energy & fuel consumption of the IONIQ range with other vehicles. The actual energy & fuel consumption will depend on many factors, including your driving habits, the prevailing conditions and your vehicle’s equipment, condition and use.

What is a fuel cell?

 It is a device that converts chemical potential energy from hydrogen into electrical energy.

How do I refuel the NEXO?

The Hyundai NEXO Fuel Cell SUV requires hydrogen gas to be filled under high pressure (up to 700bar) into its on-board hydrogen storage tanks. This is done using a specific type of re-fuelling infrastructure. Hyundai New Zealand is one of the founding members of the New Zealand Hydrogen Association and is currently working with a number of New Zealand companies to commission New Zealand’s first hydrogen re-fuelling station.       

How long does it take to fill up the NEXO Hydrogen tank?

 It takes 5 minutes to fuel a NEXO (700bar) at a commercial fuelling station.

How far can I drive with on full tank?

You can travel up to 666 km on full hydrogen tanks (WLTP*).

*The Worldwide Harmonised Light Vehicles Test Procedure (WLTP) is a global harmonised standard for determining the levels of pollutants and CO2 emissions, fuel or energy consumption, and electric range from light-duty vehicles (passenger cars and light commercial vans).

What type of maintenance is required for the hydrogen tank?

 Hydrogen tanks are maintenance free, but will require periodic safety inspections.

How safe is the hydrogen tank?

The hydrogen storage tanks used in NEXO have undergone strict testing, certification to meet ISO standards. The tanks themselves are over one inch thick made of carbon fibre and consist of a five multi-layer structure to ensure they are impact resistant, stress resistant, fire resistant and have good shock absorption.     

When will the NEXO be available for purchase in New Zealand?

 Until refuelling infrastructure is in place we are not in a position to sell NEXO. By registering your interest here you will be notified when it does become available.

How much does a NEXO cost?

 Until we are in a position to bring NEXO into New Zealand for purchase we are unable to advise how much it will cost.

When can I test drive the NEXO?

 The NEXO is currently not available for test drives. By registering your interest here you will be notified when the ability to test drive is available.
