Friendly staff. If you have the wrong type of sensor in the port in your electric car, and with the onset of cold weather, the car began to glitch and charge poorly, ask for a kettle of boiling water, and slowly pour the charging port (with the plug turned on, but without an activated charging session) this way, water will not get on the contacts, and the temperature of the port will increase, and the charging speed, or its possibility at all.
