Man Builds Tesla Auto Charging Arm at Home and Shows Demo Video

Have you ever forgotten to charge your electric car at home or meant to do it and faced the fact of having a car without a charge in the morning? This is exactly the problem that one Tesla Model S owner wanted to fix by building his own at-home auto charging arm for his car.

D. Mital's auto charging arm does fantastic things. Using an API it senses where the charge port is, open the port (shown in the video demo) and connects the charger automatically.

"I built an auto charging arm for my evtron. It senses where the charge port is, opens the port (via API) and connects the charger. It is in very early stages of development and is less than a minimally viable prototype," writes Mital in one of the Tesla Owners forum. He still doesn't have a mechanism to remove the charger after his car is automatically charged at home. I wish Tesla also provided a special API based mechanism to unlatch the automatic charger arm. "I am thinking of another mechanical hack to add something on top of the charger to press that button, but looking for better ideas," he wrote.

Miltal wrote that he built this auto charger because from time to time he kept on forgetting to put the charger in. "Many times I put it in and then had to leave for something so then remove it and put it back on"

Tesla owners never stop at gas stations for gas at least. Now Mital's plan is to never go in the garage for the car at least. The plan is to never go in the garage for the car at least. Thus the arm would auto charge it, then disconnect itself when charge The arm charges it and then disconnects when charged or when he summons to unpark. All of this should be able to be controlled from an API.

Mital wrote that he may productize it at some point. But now it's just a part time hobby.

The solution is really cool It's actually much better than using an inductive charging pad. Auto charging arm is like convenience without the extra loss of electricity. The cool thing is that since it works based off an API the owner doesn't have to be there during the process. "It opens the charge port from the API. You do need to put in your tesla ID and password into the API," says Mital.

Two Improvement Considerations for an EV Auto Charging Arm

• Any EV auto charger needs to sense if the car is present in the garage.
• It would be best if the auto charging arm came down from the ceiling.

Overall, this is a very interesting idea to auto charge your Tesla or any EV.
