Dwell time matters
How long do you actually want drivers to stay or dwell on your site for, whilst they are charging?
Will they likely need to charge for a long period of time to "fill up" or might they just need a short sharp boost or top-up?
How does this affect how long you actually want the EV driver to be at your site for?
Are there opportunities for you to capitalise on their presence through cross-selling?
Can you enhance the customer experience by providing an offer that really makes their stop memorable or enjoyable, meaning they choose your site over others?
