With the open-source project EVerest, we want to remove the obstacles to electromobility: different mature implementations of relevant standards and incompatibilities due to software island solutions at the charging stations. In chargeBIG, we found a partner early on who, like us, is convinced of the advantages of a standardized and holistic solution for the charging infrastructure. This, coupled with a great deal of know-how, enthusiasm and innovative spirit, characterizes the collaboration with chargeBIG.
