How do CPOs and MSPs work together?

We know the EV industry can be awash with acronyms and difficult terms, but we have tried to simplify it for you below:

Charge Point Operators (CPOs) 
These are the companies that operate the charge points. CPOs install the charge point, take care of maintenance and determine which billing model (per kilowatt-hour, per minute or per charging session) applies. In many cities, public utilities operate their own charge points, additional to many private companies. 

Mobility Service Providers (MSPs) / Roaming providers
These companies give you access to the charge points of many different CPOs. Because there are so many CPOs, the charging infrastructure is very fragmented. MSPs, or roaming providers, solve this by making agreements with CPOs and connecting their charge points in a so-called roaming network. Creating these connected networks simplifies it for you and often means you need just one charge card. Therefore, as a driver, you have the best charge point coverage possible, and you don't have to carry a wallet full of charge cards with you.
