Chargers

Mature Technology Proven Overseas

The charging technology has been used reliably in the USA and Europe, and adapted for use in New Zealand by Zap Fuel in the last three years

DC Chargers

  • ABB Terra Fast Chargers, floor-mounted, with touch screen, serving CHAdeMO and CCS1&2 charging standards, programmed to suit needs of Charge Point Operators, integration with Thundergrid via OCPP to provide user helpdesk support and billing services, with Modbus register interfacing

  • ABB Terra wall-mounted, with touch screen, serving CHAdeMO and CCS1&2 charging standards, integration with Thundergrid via OCPP to provide user helpdesk support and billing services

AC chargers

  • Etrel Inch Pro 22kW Unit, ergonomic floor-standing

  • Etrel Inch Duo 22kW Unit, ergonomic floor-standing, with flex-loading according to the availability of the upstream supply, and works with smart meters on power supply for real-time information

Power Supply Infrastructure

Reliable and Robust

Solar power is renewable and helps mitigate grid limitations when working together as a hybrid solution. This ensures reliable service continuity.

The battery technology sustains ample capacity through off-gen periods during the day when solar energy is low.

Thundergrid Management Platform

Scalable and Future-Proof

The chargers integrate with Thundergrid – a system that manages multiple charging networks and enables customer services including booking, help desk, billing, and roaming. The interworking is via the open standard OCPP/OCPI protocol.

Dynamic Load Management is provided, which is a key to large scale charging with minimal queuing, and is the future of green transportation. It monitors the load in both EV chargers and adjacent buildings, and balances their needs. Charging is slowed down as required until the power supply improves, to ensure electricity capacity is never exceeded.

This avoids load peaks causing power outages and the need for power infrastructure upgrades. It also allows drivers who need a quick top-up to set priority charging on their car to ensure it is charged when they need it.
