In a captivating display of innovation, a recent Butter_EV YouTube Channel video reveals the fascinating potential of using large EV batteries at campsites to power an RV’s amenities, like its air conditioning. This showcases the possibilities for off-grid camping, or “boondocking,” where travelers can escape the tether of utility hookups.
Attempting to Power an RV Using an EV
The video delves into a unique experiment where the host tries to power his mid-sized, two-axle travel trailer via a 240V plug from his truck. This strategy could be a game-changer for RV parks, leveraging excess electricity to charge the vehicle rapidly.
Initially, the presenter confirms that the RV’s air conditioners work perfectly with the campsite’s 50-amp power supply. However, things get interesting when he attempts to charge his truck using the same source while simultaneously keeping the RV’s systems operational.
The Set-Up and Attempt
To charge his truck, the presenter first connects a Tesla Mobile connector to the campsite’s power pedestal. He then tries connecting the RV to the truck’s 240V outlet. The truck initially accepts the Level 2 charge from the RV pedestal, only to later cut the power supply to the RV when both the RV and the truck are plugged in, shutting off the air conditioning.
The Challenge of Power Management
The central conundrum seems to be Tesla’s power management system preventing simultaneous charging and power supply to external devices. This is likely designed to preserve the vehicle’s battery and prevent scenarios where the truck could be drained rather than charged.
Possible Future Updates
Tantalizing rumors suggest Tesla might unlock the feature allowing simultaneous power flow in both directions in an upcoming software update. This could potentially revolutionize how RVers manage their power needs at campsites.
Practical Implications at RV Parks
Even with these possibilities, there are practical considerations at RV parks. Most power pedestals offer multiple connection types, and EV users typically prioritize using the strongest supply for charging. There remains a delicate balance with power usage as most RVs suitable for EV towing won’t exceed 30 amps, though caution is advised when using high-power appliances simultaneously.
Concluding Thoughts
To sum up, while the prospect of efficiently powering both an RV and an EV from the same campsite power source is tantalizing, it might be simpler, for the time being, to connect them separately to the pedestal to ensure stable power for all devices.
