We are looking at purchasing our first electric car. It will be primarily used for comuniting to and from work so less the 50km/30miles a day. The dealers tell us this would recharge in a few hours on a 240v 10amp gpo at home. I have no reason to not believe them but is this the best thing for the life of the battery? Or should the plan be to run the battery down and charge for longer at home or visit a fast charger once a week?
Also for not it will be used for longer trips 2 or 3 times a year. Up to 1200 km round trip.
It won’t have any detrimental affect on the battery whatsoever. In fact charging somewhat slower than the more normal 32A/7.2kW can help it last longer. There’s no particular reason to visit a fast charger, but running the battery down and fully topping it up occasionally does help, but we aren’t talking weekly.
Work out if 10A 2.4kW is going to give you what you need, simply Size of Battery / 2.4 will give you the hours to charge from 0-100% then take some fraction of that since you’ll never be charging from zero.
Keep in mind the main failure mode here is in using the normal domestric plug, it’s worth getting it checked by an electrician first, often they can install more robust versions.
