Not all public charging infrastructure is compatible with every vehicle model, and this also applies to BMW vehicles. Specifically, some stations may not support the connector types required for this vehicle, making charging complicated, whether from alternating current (AC) or direct current (DC). This helps explain why, in some cases,BMW vehicles fail to start or complete charging at certain public charging stations. Furthermore, software issues, such as missing updates to the on-board system or the dedicated app, can prevent charging sessions from starting. Charging infrastructure is managed by different companies, and software updates often vary between providers. A useful first step is to check the name of the station operator to identify any anomalies and recurring situations. It's also advisable to try charging at other stations belonging to the same network or from different providers to gain a more complete picture of the situation. If the service works properly at other locations, the problem may be related to an update not yet released by the previous provider. The compatibility of public charging stations also depends on the subscription or authentication required: some networks require a subscription to use the charging service. Check whether you need a card or specific credentials, as without them, the session will not start. Furthermore, some stations require the use of a dedicated smartphone app; if you don't have the app installed, this could explain the charging failure. Don't overlook the connector type either: some sockets may have a slightly different shape, preventing a perfect connection and thus preventing charging. As you can see, there are many possible causes that could prevent your BMW from recharging at some public charging stations.
