EV Charging Station Guide
All home EV charging stations do the same thing in that they are an extension cord to the car. The actual charger is in the car. Any charging station can charge any car as long as the cord can be plugged into the car. Each charging station will have various features that may or may not appeal to you or your installation situation.
Cord End:
NACS (Tesla) or J1772 (non-Tesla) – There are adapters to go between each option which means any charging station can charge any car
Cord Length:
Length of cord from the charging station to the car
WiFi Enabled:
WiFi connections allow for remote troubleshooting and firmware updates by the manufacturer
Circuit Size:
The breaker size of the circuit
Cord Length:
Length of cord from the charging station to the car
Load Sharing Capable:
This allows multiple charging stations to share a single circuit. When multiple charging stations are in use, they will split the amperage of the single circuit. When only one is in use, it will get the full value of the circuit. This only works with the same brand units. A Tesla Wall Connector can’t share with a JuiceBox.
Load Management Capable:
This requires an accessory to the charging station that reads how much power a breaker box is using when charging and adjusts the output of the charging station so the breaker box is not overloaded. This is useful to avoid longer circuit runs or service upgrades.
Max Austin Energy Rebate:
The maximum rebate Austin Energy would give back on a charging station and it’s installation. The rebate is for 50% back up to the maximum amount based on the charging station. It could be less than the maximum amount on less expensive installations.

Tesla Power Meter for Smart EV Charging
This is an accessory to Tesla Wall Connectors. It mounts in the breaker box feeding the wall connector and reads how much power the rest of the box is using while you are charging. It will dynamically adjust the output of the wall connector based on those other loads so you don’t overload the breaker box.
