Secure Vehicle Software Updates Via Private Network

A computing system for providing OTA updates at a charge station or other location can include a local cache storage; a communications system configured to establish a private cellular network associated with a particular location; and a control circuit. The control circuit can be configured to: obtain an OTA software package from an OTA update server over a public cellular network; store the OTA software package at the local cache storage at the particular location; determine that a vehicle has connected to the private cellular network; in response to determining that the vehicle has connected to the private cellular network, determine whether the vehicle is eligible for the OTA software package stored at the local cache storage; and provide, over the private cellular network, the OTA software package stored at the local cache storage to the vehicle based on determining that the vehicle is eligible for the OTA software package.
