Electric vehicle trial data is now available to innovators.
The 3-year Consumers, Vehicles and Energy Integration (CVEI) project was the UK’s largest and most comprehensive set of trials on consumer behaviour and attitudes towards electric vehicles and smart charging. With 450 mass-market consumers carrying out 584,000 miles of journeys and 15,700 charge events using electric, plug-in hybrid and petrol cars.
CVEI was an innovative and ambitious project commissioned and funded by the Energy Technologies Institute (ETI), and delivered by a cross-industry consortium led by TRL.
Energy Systems Catapult provided technical expertise and assurance to the project and now owns the data and models to provide future development of the CVEI capability from the ETI legacy.
We have made the consumer trial data from the CVEI project, publicly available for the first time.
- Data from the Vehicle Uptake Trial where 200 mainstream consumers experienced each version of a VW Golf for four days – including conventional petrol (or ICE), fully battery-electric (BEV) and plug-in hybrid (PHEV) – to understand the barriers and motivators influencing the uptake of plug-in electric vehicles (EV) by mainstream consumers.
- Data from the Charging Behaviour Trial where 247 mainstream consumers were given either a fully battery-electric (BEV) or plug-in hybrid (PHEV) version of a VW Golf over a two-month period. Data was collected from journeys and charging events to understand the effects of different managed charging schemes on charging behaviour, how likely participants are to engage with managed charging, and to identify factors that could encourage engagement.
How can this electric vehicle data be used?
The data can be used to gain insight into how mass-market consumers use and charge both battery electric vehicles (BEVs) and plug-in hybrid electric vehicles (PHEVs). You can analyse the data to see how different managed-charging tariff options affect these behaviours (both user-managed charging and supplier-managed charging in different seasons). The data also helps to understand the changes that will be required of existing infrastructure to accelerate the growth in low carbon transport.
How can I access the data?
This data is now available to access in three tiers. Please click on the tier for more information, or visit the USMART platform here.
The Bronze tier allows users to get a picture of how different user groups (classifications include vehicle type, tariff type, season, etc.) utilised and charged their vehicles over the 8-week trial period.
The Silver level of access provides participant-level aggregated data for charge events and journeys, providing valuable statistical insight into participant-level behaviour. As well as this data the Silver access tier also provides generic Python scripts that can be used to import data into a Python environment and then generate pertinent graphical outputs to help explore and interpret the data.
The Gold tier will provide you with access to discrete event-based data allowing a wide range of analysis to be undertaken into participant behaviours. This tier also includes support from specialist transport consultants at Energy Systems Catapult. Support can be tailored to your needs, for example, through the provision of workshops, training or the time of an analyst to help with processing and interpreting data.
Who will benefit from this data?
This data could be useful to a wide group of interested parties, including charge point operators, energy providers, vehicle manufacturers and research bodies.
About the EV project and trials
The 3-year CVEI project aimed to deliver unique and detailed insight on mainstream consumer behaviour when using and charging battery and plug-in hybrid electric vehicles, to understand the changes that will be required of existing infrastructure with the growth in low carbon transport.
The project was carried out in two stages. The first stage focused on detailed analysis and design of market, policy and regulatory frameworks, business models and customer offerings, electricity and liquid fuel infrastructure and technologies throughout the energy system as well as at charging and refuelling points and on-vehicle. This was supported by insights from consumers and fleets on the use of plug-in vehicles.
The second stage delivered trials involving approximately 450 mass-market users to validate the impact of solutions identified in stage one and understand consumer and fleet responses to the vehicles and to managed charging schemes. At this stage, two separate sets of trials were carried out; the Charging Behaviour Trial and the Vehicle Uptake Trial.
The Vehicle Uptake Trial recruited 200 participants who experienced a conventional petrol (or ICE), fully battery-electric (BEV) and plug-in hybrid (PHEV) version of the VW Golf for four days each. The objective of these trials was to understand the likely uptake of plug-in electric vehicles by mainstream consumers.
The Charging Behaviour Trial was designed to provide data on the charging behaviours of mainstream consumers using electric vehicles, understand the effects that managed charging schemes have on EV smart charging behaviour, how likely participants are to engage with them, and finally identify factors that could encourage engagement.
There were 247 mainstream consumers that participated. They were given a vehicle, either fully battery-electric (BEV) or plug-in hybrid (PHEV). The same type of car was given to both sets of participants, a VW Golf. Over the two-month period that each consumer had the vehicle, data was collected both the journeys the vehicle was used for and each of the charging events it underwent.
