Of course, the battery can also be charged to 100% directly before a longer trip on the motorway. But even when charging stops over longer distances, it is advisable to charge the battery to a maximum of 70% to 80%, because the charging speed drops quite significantly in this range. So you don't waste any time. The important thing is never to leave your electric car at 100% for a long period of time. It is recommended to charge to 80% before a longer absence so that the vehicle always has enough energy available.
