First electric double-deck buses in the WORLD in Wellington, New Zealand


10 Buses Wellington, New Zealand 9 Months
CCS Roof-mounted pantograph


Tranzit, the local public transport operator  was looking for a reliable solution to fast charge their 10 electric double-deck buses in New Zealand's capital city Wellington. This project was to be the first all-electric bus fleet to start operating in New Zealand and the very first all-electric double-deck bus fleet in the world. Tranzit was interested in opportunity charging, which would allow the highest uptime and availability for their fleet. A challenge for the customer was also the versatile landscape ,where the double-deck buses operate and making sure that despite the challenges the up-times of the fleet would be optimal.


Heliox supplied 8 fast chargers together with the Bus-Up (roof-mounted pantrograph) solution to charge the very first double-deck e-buses in the world. In order to meet the requirements of the customer Heliox provided  a combination of opportunity and overnight charging, comprising of five Heliox FAST DC 2x30kW chargers, two Heliox OC 450kW chargers and one Heliox FAST DC 25kW mobile charger with a plug-in option for ultimate flexibility in the workshop. In the depot the buses can charge by using the CCS plug-in system and en route the buses are being charged by using the Bus-Up system, with a pantograph mounted on the doubledeckers. This project is a great example of the strength of open interfaces and the open source OCPP back-office communication, which gathers data from the infrastructure and the EV bus fleet.


This project is great example how Heliox’s open technology supports bus operations with different suppliers all over the world.  Heliox is excited to have provided chargers to the very first full electric double deck buses in Wellington, New Zealand. Our robust and reliable solution, which support the Bus-Up (roof-mounted) system, deliver maximum availability and increased uptime to the EV fleet.  Keven Snelgrove, Transport and Operations Director for Tranzit Group: “We’re excited to be the first users in the Southern Hemisphere of fast charge technology. Heliox have been professional partner to date, their experience and proven robust charging infrastructure was a key factor in our decision-making process. The charging stations are very discreet and will be placed strategically on our routes for greater range around Wellington. We’re delighted that Wellington are investigating into New Zealand’s first fully-electric bus fleet.”
