How to add EV charging fee to listing

[Daniel14037]

Hi,

I'm in Australia and have just had the first guest with an EV. They tripped the power and said they were only using an electric frypan, but I've since found they have been charging their Model 3 Tesla.

In light of this property being affordable, I need to add an additional EV charging fee, but can't add it in the additional charges section.

I wonder how other hosts are charging their guests for charging their EV's.

For reference, my electricity provider charges 40.5¢/kWh peak & 24.6¢/kWh off-peak.

A Tesla model 3 long range has a 79kWh

battery. 

The Australian government Green vehicle guide home charging calculator says it will take ~33 hours and cost AUD$32 for a full charge.

The Airbnb is on my rural property, we rely on electricity for our five water pumps (main house, Airbnb cottage, grey water, irrigation & dam-to-irrigation tank filling) electric hot water, heating and cooking - when these guests charged their car, it tripped the power to our main house water pump - coming off the same breaker board.

I don't want to encourage ev charging so I'm going to charge a flat rate $40/24hr fee.

Any insight as to how to add this fee option greatly appreciated.

Thanks in advance!

If you don't have an EV charging station, I'm assuming the guest was using a regular outlet to charge? It will be difficult to monitor who is and isn't charging an EV. Perhaps a camera outside? How are you planning on preventing a circuit breaker from tripping again? 

If you come up with a plan to prevent the electrical issues, I would add something to your addl House Rules, Other Details under description and House Manual that EV charging is available for a fee that must be paid prior to charging a vehicle. You would do this through the resolution center. A guest can send you money, or you can send a charge to the guest for them to pay. It is done via the "Send or Request Money" section of the Reservation Details. 

Some Hosts who have installed an EV charging station are able to monitor use via an App and can charge accordingly. Others put a lock on the EV charging station to prevent someone using it without paying a fee first. Other Hosts in other parts of the world have very reasonable electrical rates and don't charge guests to use their EV charging station.

@Daniel14037.  Our most affordable place has street only parking so a very long extension cord would be required (as well as highly visible to cameras). Disable any external power points and dont provide long extension cords to make it more difficult to plug in.

I'd be careful about setting an EV usage fee that you cannot track unless its separately metered to your other buildings as you run the risk they just wont tell you or refuse to pay.

In hot weather its pretty hard for an older place to have sufficient power to run a fridge, a/c, oven, large TV and an EV. If it was separately metered you could just write that the power provided has limitations of x kWh then when its tripped its their problem (and yes maybe yours, review wise). I just think you need to remind guests of this.

Maybe also have info on nearest EV charging stations.

Hope this helps.
