The Network Filter is available with an active chargEV Plus subscription.
Networks are either large operators (Tesla, BP pulse, IONITY, …) or cooperations of smaller operators (Ladenetz, TankE, …) who have identical access requirements (as they allow roaming within the network).
The Networks feature allows to only display stations of a single or of multiple networks which is useful when you have special tariffs or discounts valid in a specific network only (e.g. time-limited discount at IONITY when buying a special car brand, promotions such as free charging on a specific day on a specific network, Tesla Destination charger, …).
You can also use the networks feature to exclude a specific network only (activate all networks, just disable the unwanted one).
As the number of networks known to chargEV is still limited and continuously growing it is not recommended to use the networks feature to only exclude networks. When using this approach, all networks still unknown to chargEV will also be excluded.
