Batteries & Chargers…

[Junior Tibby]

I currently have a BMW i3 and have been thinking of ways to perform upgrades to keep it current. At the moment it charges at a max of 7kw and only via type 2. It also has a battery that has a max range of 100 miles. I live in the UK and was wondering if it’s possible to not only upgrade the HV battery but also change the charging system to increase charging speed? Thanks in advance for any advice.

I don't believe you can increase charging speeds when charging via AC level 2 as the built-in charger in the car can only handle that. You would need to use a DC fast charger (up to 50kw) as the only faster option. There are people who have upgraded the battery, up to the largest 120ah version but it is very expensive as you would imagine. BMW made all 3 batteries physically the same size and you can upgrade in-place if needed.
