Hey, I like what you've done with the redesign of the charging screen. It's one of those things that you don't really realize how much room it has for improvement until someone goes and does it.

I do think that you need to tread carefully introducing some of the marketing/brand building type stuff into the car UI. IMO, the car should have the sole purpose of clearly presenting essential information and controls without ulterior motives. I've already purchased the car, and the ownership experience itself reinforces the brand. There are times and places for this sort of thing, but not in the product itself IMO. If I could get an email or report in the app once per month with the same savings info, that would be a better balance of useful and promotional.

I do understand the "value over cost" concept, but I'm not sure that a selling technique serves the goal of creating a better experience for the user. When pulling into a supercharger, the key pieces of info that I need to know are how long it will take, how far I can drive on the charge, how much I'm paying for the service. The latter has been demoted in the hierarchy in service of brand building.

Simple solution: swap the savings and cost figures. I think that the savings message is sort of implicit in the rock-bottom price anyway. That $0.42 price itself could be something that you want to highlight, given that a tank of gas can cost $50+.

That aside, let's just assume that the promo stuff was a business requirement, in which case I think you did a great job putting the financial and environmental impact in terms that are easy to understand.

Great work!

Just thought I'd give a bit of context for this story:

I've been really impressed with the Model 3… so much that after the last time I brought it to a Supercharger while driving down to Boston… I took 80 hours to: - Interview Tesla drivers - Identify the top pain points with the charging experience - Analyze possible solutions - Wireframe a couple of layouts - Redesign every step of the experience I went through (including ways that Tesla could drive more word-of-mouth and focus on the environmental benefits.)

The result is this interactive "comic book style" analysis on Tesla.

I'd love to get your feedback on it.

PS: Do you think some of the redesigns I suggested would make sense? What would do you like/would improve? (Please mention if you're driving a Tesla/EV in your reply, that'll give me some context)

PPS: I keep editing the slides based on your feedback so thanks for sharing what you like/dislike! :)

Hi Dan,

I really like your idea and how it’s presented. I can imagine there is some sort of self-marketing behind this as well ;) Anyway, really nice concept which shows that current Tesla user experience still has some room for improvement.

I'm not owning a Tesla but I have some experience in creating UX for automotive industry. So here some comments from my side:

I’m not familiar with Tesla touch-screen interaction model but I can imagine that hiding critical settings like „Advanced Options“ to scrollable panel is not a good idea, especially in automotive interface. It might be good for long lists like address book entries but it’s very unhandy for important options. Since we are in charging context all options associated with this process should be visible at one glance. And I believe there are plenty of use cases where people would like to have everything on one spot. Imagine, you want to schedule charging for the middle of the night when electricity is cheaper. Then you need to scroll down every time for this setup.

If you think some technical terms are too confusing for average users then just make those options more explicit by wording or visually instead of hiding everything away from main screen. Otherwise people will just overlook it.

It’s really great idea to emphasize value over cost. But to be honest I’m not sure that highlighting savings is so relevant for the majority of Tesla owners ;) I believe if you buy such luxurious car the last thing you think about is cost savings. There is no real need to try to promote this idea when you allready own this car.

But rewarding your customers for charging from renewable energy sources could be a great idea!

I might be wrong but Advanced Options layout looks very desolate to me. There is a huge gap on the right hand. I believe there are better ways to present this information ;)

The new "Savings" section looks really nice but I was not able to spot the menu button right away…You also made Stop Charging button less important by changing its style to outline. You should also take care of putting navigation buttons and critical actions in one line. Personally I think it could be a nice to have add-on for your mobile device. Or you can display this information while charging process. But I'm a bit sceptical if most people will take care of this information at all.

The „fully charged“ confirmation is really nicely designed. Do you think it is something you would like to see just after getting into your car? I believe the next thing most people want to do is just drive. In this case this message acts as disruption without any crucial function. Why not just drop a message on your mobile phone that your car is fully charged? I can imagine most drivers don't wait inside the car until fully charged.

The one UI change that made the most sense was pushing down the charge current and scheduled charging in the hierarchy. Great work!

I'd bet they put the other charging locations prominently in the mobile app because some charging stations are full (which would be annoying).
