Enginer Switch Update

[cabledave]

We replaced our Enginer switch setup with the OEM EV switch + a nice clean looking rocker switch to turn the PHEV on/off.

Also replaced the red LED with a buzzer, since I have yet to notice the red LED when it has lit up.

I very much prefer this new setup. It not only looks 1000% better, the feel of the EV switch in operation is much nicer and it may be a coincidence but I found that the EV mode engaged much more often yesterday. It is still pretty warm here so I don't think it was a temp change.

Wow, that looks real nice! I think I might have to take that approach too. I like the buzzer idea since I haven't noticed the red LED coming on either. Stupid question, does your buzzer come on when the pack is low? I was trying to figure out if the lack of red LED was a signaling issue or an LED issue...

We haven't had a chance to run the battery down yet. I'll post here after we have confirmed it works.

Here is the link to the buzzer we used:

Question for you... Is your EV switch set up to work in parallel with the Enginer EV mode or did you disconnect the Enginer EV controls and you run your EV switch separately?

I had an EV switch installed before I got the Enginer kit, so I didn't hook up the EV mode from the kit. I'm not getting the performance increase I expected from the kit, so I might just hook up the kit wires in addition to my switch.

Our EV switch is separate from the Enginer switch now.

I like having the EV switch separate as there isn't a logical reason to turn the PHEV on and off just to get into EV mode.

Then you disconnected the Enginer EV switch wires and put them on your new switch (or that's the net result...)?

Yes. The EV switch is now on its own.

Thanks. That's how mine is setup, but I'm not getting a big boost from the kit yet...might just need to wait for battery break-in a little longer.

The buzzer is a good idea but it is still binary, either you have juice or you don't. I use a digital voltmeter to monitor the pack voltage. It's like a gas gauge. You have a full tank at 52.0V (converter on)and an empty tank at 46.0V. It drops fairly quickly at the beginning and the end but is pretty linear in the middle. It's actually better than the Prius gas gauge for letting you know how much is left. The only caveat is that you need a good voltmeter because the cheap ones will drift and give bad readings.

Hmmm..I've got a WATT'S UP on my 48 volt e-bike that works quite well. I'm told the shunt can be replaced (or augmented) as well for amp-hours...
