Hello everyone! We are postgraduate students who are working on this survey to establish if there is a demand for improved electric vehicle charging infrastructure and interaction in the UK. We would appreciate your time and the responses that you provide and all answers will be collected confidentially.

Thank you for your time and support.

Q12 ignores home charging. If you charge at home then none of the options apply. Did you mean this to apply to away from home/workplace charging only?
Q17 needs some work. Whats the difference between an "issue" and a "problem" ? And the middle option "Neither a problem nor not a problem" is nonsensical.
Q17 also fails to distinguish between Tesla EV users and others. Tesla are a on a different planet when it comes to charger availability. My answer to this question would be radically different depending if i had a Tesla or not. Its also problematic what you mean by the "EV community" If i have a Tesla am i bothered that lowly Hyundai Kona users will find it problematic to charge at motorway service stations? Do i even know?
Q18 implies that there is currently no app that tells you where chargers are. But there are several already (and if you have a Tesla its built in as well but is it an "app"?. There should be an option "already use such an app/have that capability" .

However, bottom line is anyone who drives an EV would already tell you there is a demand for "improved electric vehicle charging infrastructure". No survey needed. I dont see how you'd get any quantitative data from your survey to add to that.
You dont (for example) ask;
Are there any trips you haven't made in an EV due to paucity of charging infrastructure along route?
Have you ever failed to obtain a charge and had to curtail a trip?

I'll add - take a look at Q 9 and 10
Wall socket - OK
Level2 (US terminology) is NOT a charger this is a clever socket and uses the cars built in charger just like the standard socket .
we know this as a fast charger. and its rated 7 to 22kW. there is a slow version (3.5kW) found in some areas.
In the UK only 3.5 and 7kW are found in the home. the 11 and 22 varients are 3phase.

Level 3 (US terminology) is a DC charger known as a Rapid here.

Q15 - given the current state of the infrastructure (apart from tesla) always sort out charge points Before setting off. Never try to work out on the go
Q18 your kidding, this shows you have never had or used an EV. There are "Apps"
Your use of terms is likely to produce erronious results.

The questions imply that the setters have not used an EV/ Owned One/Hired one and have read some american sites on charging. University of Edinburgh really! Nip down the local nissan dealer and ask for a test drive first please then rewrite the questionaire in english so it makes sense.

Just to add, like all these surveys it asks for your age, sex etc (why oh why ohwhy?? Just because everyone else does?) but not where you are located in the UK ! This surely is much more indicative of any charging problems you will encounter than whether you are a 32 year old female or a grouchy 60+ bloke.

It's a good point regarding location.

General demographic data is collected as a means of understanding broadly the type of population your data is collected from.

Whilst there may be no real relationship between these and the outcome (although I think it's legitimate to account for age when discussing apps and access to technology..) it allows you to determine how generalisable the survey results are. If, for example, the survey only happens to gain responses from males, then it's perfectly understandable to caveat these findings with that fact. Same with age.

When surveying samples in order to try and understand broad issues, it's pertinent that the sample is representative of the whole, otherwise it may be biased. The only way you can know is if you ask....

I'm afraid I no longer bother with most surveys. Even professional ones often have poorly worded or ambiguous questions and/or a lack of choices that match my feelings. Unfortunately surveys pushed out by students as part of some project are usually even worse.

There's a reason why things like referendum questions are carefully crafted by serious people - asking a question that means the same to everyone and will elicit a valid answer is not as easy as the average social media user thinks.

I answered the survey but I'm not sure what you are trying to find out.

What is your research question?
