Personal second- and third-level support for EV chargers – multi-vendor, with my own lab for test installations.
I am Sebastian Böttger, self-employed since 1995. Under charger-support.com I offer second- and third-level support for EV charger manufacturers: on their behalf I support customers and installation partners, track down the root cause of field failures between charger, network and backend, and write it up so that R&D and support can work with it.
