Re: Key In Fob

Sure you would... just smash a window and you're in. Who needs that pesky key in the fob?

Re: IP address (or) MAC address

If you connect to your personal wifi network when parked at home, you can probably see the MAC addresses for all devices (including the FFE) somewhere in your router/AP admin page. Btw, the IP address assigned to the car (by your router/AP) when connected to your personal wifi network will mean noth...

When your FFE was new, you probably would have seen around 19 kWh, or even more, for the run-down test.

So, you have approximate battery fade of at least 15%.

Re: 2017 FFE light sensor

Sorry no.

Maybe leave a dead sparrow on top of the sensor to stop it from changing all the time?

Re: EMF magnetic radiation

No idea.

Curious, though. If you are concerned about exposure to electromagnetic effects, why did you buy an electric car?

Re: Guess-o-meter strangeness

As others answered - yes that's exactly how the GOM works. It is very sensitive to changes in driving / energy use. Think about it, typical range of the FFE (23 kWh) battery is only about 75 miles (under ideal normal use). That's like driving a gas car that only carries about 3 gallons of gas, perh...

Re: Completely at a loss

Best thing I ever did for my FFE was install an Optima D35 battery to replace the original Motorcrap battery. https://www.amazon.com/Optima-Batteries-8040-218-YellowTop-Purpose/dp/B000MSDKMA The D35 fits perfectly in the FFE battery holder. If you can afford it, you will not regret having an Optima.

Re: Which plug to use 240 or 120

Charger input: 26A at 241VAC Charger output: 16A at 349VDC Roughly 89% efficiency if my math is right.. Note that the process of charging the battery itself is also around 90% efficient. What you have measured is basically the efficiency of the charger in 1) converting voltage and 2) converting fro...

Re: Which plug to use 240 or 120

So, with gas too, faster is better. Faster is not really better with charging. Faster charging means more current, means more heat, means more harmful to the battery. Excess heat, yes. But, generally speaking, being warmer is more optimal... warmer batteries perform better. And some battery chemist...

Re: Which plug to use 240 or 120

there is none in the gas filling example. Technically, the longer you take to fill a gas tank, the more time you allow for some gasoline to evaporate in the process (since the tank is unsealed, plus gas is flowing with some exposure to the atmosphere). So, with gas too, faster is better. (Granted, ...
