The Tesla Wall Connector is a home EV charger with many functionalities, including power-sharing, which users can activate fairly easily. Power-sharing is an interesting Wall Connector feature that enables homes with multiple Tesla EVs to recharge their cars simultaneously. Although it works using one electric circuit, the functionality ensures that all the EVs maintain a healthy charging speed. Power-sharing charges up to six vehicles using six connectors. To avoid sending unhealthy amounts of current, one of the Wall Connectors is assigned as a leader and regulates the charge sent to the others.
According to Tesla, anyone interested in establishing a power-sharing network should hire one of its qualified technicians. The electrician will need to identify and configure one connector as the leader. Households should know that power-sharing is obtainable only when the connectors run on firmware version 21.36.6 or later. When the first Wall Connector is successfully configured, the next step is tapping the power-sharing card located in the commissioning interface and pairing the remaining connectors to the leader using Wi-Fi. Tesla states that during the process of adding chargers to the network, the lead unit will briefly relinquish its Wi-Fi connection. It should be instantly restored, but if it isn’t, refreshing the page should fix it.
Troubleshooting Tesla Power-Sharing Issues
Once the remaining connectors have been included, the next phase is setting a network limit which will ensure that each connector isn’t fed abnormal current. Tesla says that a six-unit network has a limit of 36 amps. Also, if each charger has a different circuit breaker, the technician must unite the connectors using their respective breakers. Once the six chargers have been linked and a power limit set, users will be able to turn on power-sharing. Unless activated, homeowners can’t charge multiple EVs using the Wall Connector. It should be noted that only Gen 3 Wall Connectors can be used for this purpose.
Tesla prescribes some solutions to address issues with the power-sharing functionality. The most common reason for a break in the process is the failure of the lead unit to connect with the other units. When this occurs, there are a couple of remedies that can be utilized. One of them is to verify that the connectors are activated. Another method is to power cycle the Wall Connectors, which should restart the circuit breaker.
The Wall Connector is a smart charger designed to make home charging more convenient. It’s a Level 2 EV charger, meaning that users can add more miles in fewer hours compared to the mobile cord. It currently offers up to 44 miles of driving range per hour. It features Wi-Fi connectivity, a feature that enables households to easily download and install over-the-air firmware updates. Buyers can leverage its Charging Access Control feature to determine which EV can be recharged through the connector. The Wall Connector is available in two variants — the regular version costs $350 while the J1772 charger (for non-Tesla EVs) is priced at $550.
