Wow, here we are approaching the four year anniversary of El Ohmbre. The batteries have lasted much longer than I ever would have imagined. I’ve been working at home still for the past year so I don’t have any regular commute any more. In addition, my brother in law has returned from his last tour of duty in Afghanistan and is staying with us. He’s been parking his car in the driveway behind el ohmbre so on some days when I’d normally drive it, it’s blocked in. Therefore I’ve been driving my gas car much more than I’d like. Just as a good reminder of how nice it is to have the electric car, my gas car is leaking coolant and burning oil. Naturally the coolant leak can’t be in some nice accessible place. It’s on the back side of heads up against the firewall. I have no idea how to get to it without pulling the engine.
It’s hard to tell what range the batteries will support these days because I’m not driving the car to the limit of the batteries every day. I can park it for a week at a time and still squeeze out enough mileage to do my basic errands. I haven’t checked the specific gravity of the batteries for a long time. The water level seems to stay up fine and the batteries are holding a charge even when it doesn’t get driven every day.
I’m still thinking about replacing the lead/acid batteries with lithium ion but I haven’t done much research recently. My son is turning 16 soon and he would like to drive the electric vehicle but he would like something a bit “cooler” like a 914 Porsche. I’d be willing to do another conversion but I’d really like to test lithium batteries first. I told him that if he helped with the battery conversion, I’d help him build a cooler ev.
The first test drive in el ohmbre was May 9, 2009. In less that two weeks, we’ll celebrate the four year anniversary. If you are thinking about doing an electric conversion, I highly recommend it.
