Does Tesla Have External Discharge Function?
2 Answers
Tesla does not have an external discharge function. Currently, none of Tesla's electric vehicle models support bidirectional charging and discharging. According to overseas media reports, the Model 3's hardware already supports bidirectional functionality and only awaits official activation from the manufacturer to be used immediately. Moreover, compared to other automakers, the Model 3 does not require an additional inverter to feed electricity back into the AC grid. Below are the benefits of external discharge: More Flexible Use of Electrical Energy Bidirectional charging and discharging for electric vehicles is increasingly being emphasized or enabled by more alliances or brands. The greatest benefits are seen in commercial fleets or commercial applications. For individual users, the most significant advantage of bidirectional charging and discharging lies in its application within home renewable energy networks. Enables Vehicle-to-Vehicle Charging Mode Another benefit of bidirectional charging and discharging is the ability to allow electric vehicles to charge each other. When an electric vehicle is unable to move due to a dead or low battery, a Model 3 that supports bidirectional charging and discharging can use charging cables to directly transfer power to another Model 3 (it is not yet confirmed whether it supports other vehicle models), achieving benefits such as vehicle rescue and range sharing.
I often discuss Tesla's external discharge function with fellow car enthusiasts. Actually, Tesla didn't directly design this feature, and the factory configuration doesn't support connecting external electrical appliances. However, it can be achieved through third-party discharge converters, which work by drawing power from the charging port. I've used a 3.3KW converter several times, and it's perfectly sufficient for powering an induction cooker and a mini fridge during camping trips. Just remember to choose a converter model that supports the national standard charging port. Tesla's large battery capacity can support ordinary household appliances for over ten hours when fully charged. In my tests, running an air conditioner overnight only consumed 10% of the battery. The only downside is that the converter installation process is a bit cumbersome and requires professional guidance. For friends with frequent outdoor power needs, this solution is quite practical, though it does require spending an extra few thousand yuan on the equipment.
