EV battery data use in NZ – study
Power Trip’s new study looking at how EV battery data is being used in New Zealand explains some of the issues.
A key one identified is the need to work with vehicle manufacturers to enable wider access to battery information and to standardise how data is recorded, processed, and shared to support battery passports, says author Richard Heaps in his executive summary.
“This would improve results, support innovation, increase transparency, increase recycling rates, and support second-life applications as well as enabling a stronger, more transparent secondhand market for batteries and EVs.”
Robust data about EV battery health will be a vital pillar of the proposed Product Stewardship Scheme for large batteries here, including EV batteries.
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 suggests.
The project aims to develop a minimum viable product data portal for EV batteries.
The report developed in partnership with the Ministry for the Environment and the Energy Efficiency and Conservation Authority (EECA) is designed to provide insights to the state of play, opportunities and challenges in ascertaining EV battery health.
A webinar to discuss the report is planned early next year.
The report 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, 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, and 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.
