EV and large batteries use in New Zealand – insights from data pilot

Power Trip has released its study into how electric vehicle (EV) battery data is being used in New Zealand. The report was developed in partnership with the Ministry for the Environment and EECA (the Energy Efficiency and Conservation Authority) to provide an overview of the state of play, opportunities and challenges in ascertaining EV battery health.

Robust data about EV battery health will be a vital pillar of the proposed Product Stewardship Scheme for large batteries in New Zealand. In addition, understanding EV battery health will enable better fleet management, including how to maximise battery life through charging behaviours, and when to repair, transfer to second life uses, or recycle at end of life.

The report is based on more than 60 interviews with people in the EV and large battery sector and insights from the development of a prototype data portal for EV battery information. 

It includes:

  • Details of the portal, which was populated with data from a trial of advanced telematics devices placed in more than 40 EVs
  • Data capture opportunities
  • The benefits to fleet managers of good battery management, and the flow-on benefits to the wider sector
  • The need, and potential, for cooperation across the industry to support battery product stewardship
  • Ways to support and encourage continued innovation with these essential, emissions-reducing technologies.


The report will be used in the next phase of development of the proposed large battery product stewardship scheme in New Zealand.

Let’s power up the battery waste hierarchy

Transitioning away from fossil fuels to energy systems which use batteries can’t just be about reducing emissions during use but must take a holistic approach. This means reducing a battery’s environmental impact from the extraction of the materials which make it up, through to how it’s dealt with at the end of life.

To find the most sustainable solutions we must turn to the waste hierarchy.
