Electric vehiclesProject Jemena Dynamic Electric Vehicle Charging Trial
This is the second lessons learnt report for the Jemena Dynamic Electric Vehicle Charging Trial and shares key lessons learnt by Jemena and partner DNSP’s between 1 Jun 2021 and 31 May 22.
The purpose of this report is to share lessons learned by Jemena and partners DNSP’s during phase 2 of the project which include:
- Lessons on establishment of aggregation software platforms and testing, including the standard based approach adopted by DNSPs to communicate operating envelopes to JET Charge.
- Lessons on installations at customer premises, including any technical, logistics, health & safety and social/customer issues.
- Customer preferences survey results. This survey will be conducted before the trial takes place and will collect information such as vehicle data, ownership status, customer billing plan, EV charging bill per month, driving patterns, customer preferences for charging and proposed intervention etc. These factors will be useful in developing a more complex optimisation engine in the future to allocate spare network capacity among the EVs (simple allocation function proposed for the trial).
- Lessons on network sensor installation. Sensors will be installed at some locations to monitor network conditions dynamically. This will be necessary to forecast available capacity for EV charging. Lessons learnt will include how many EV owners are supplied by a single transformer (across different post codes) and also the challenges faced to install monitors i.e., technical, traffic management etc.
