For reference powering the charge status indicator, read this and post #130: http://www.tractorbynet.com/forums/...c-polaris-ranger-post4886706.html#post4886706

The easiest thing would be to run a wire from the power supply to one of the fused +12v Bat wires under the seat, because they have a diode that would prevent the back feed from the converter.

Could not find either diode, so I did it the "easy way". Used some small tubing to protect the wire coming from under the hood to under the seat:

Poked the wire into the tubing and pushed it through:

Spliced to the pink 12v bat wire that was on the first deep cycle battery in the series string:

Slid the covering back over to the fuse holder and put it back up out of the way:

The Voltronics power supply is only on when charging the battery packs:

It now puts it's DC voltage through a diode to the constant power wiring system causing the Charge Status Indicator to operate:

It has been about 20 days since I charged the Voltronics Lithium-ion batteries, the SOC was showing 40%:

PA180008 35%.JPG



And 189.3 hours:

PA190004 4th chg.JPG



Screen shots from before plugging in the charger, Pack voltage is 52.4 volts:

PA180003 BMS only.JPG


Right click this one and open in new tab, to see it better

PA180004.JPG



Plugged in the charger at 10:30, the Charge Status Indicator started flashing, my wiring modification is working!

Came back after lunch, SOC is up to 64.5%, 17.2 amps going into the batteries. Pack voltage is 54 volts:

PA180029 1.19.JPG



Just over 8 hours charge time, the Charge Status Indicator is on solid:

PA180048.JPG



Pack voltage is 58.7 volts:

PA180050 8.4 hours.JPG


Fourth time charging was successful.

Yikes! 58.7v? Any chance that the Sevcon and the motor will disagree with that high a voltage?

No the motor runs on three phase AC, produced by the Sevcon.

Voltronics modifies the DeltaQ charger and the Sevcon motor controller, so there shouldn't be a problem.

Re: Electric Polaris Ranger, Charging the Lithium-ions again.

It has been over three weeks since I charged the Voltronics Lithium-ion batteries, the relocated SOC meter was showing 2 bars:

PB110040.JPG



And 190.6 on the hour meter, nice to have it back in the dash:

PB110044.JPG



Screen shots with just the BMS powered, before plugging in the charger, Pack voltage is 52.5 volts SOC is 17.5%%:

PB110030.JPG


Right click the above picture and open in new tab, to see it better.


Plugged in the charger at 11:20 am, the Charge Status Indicator started flashing, my wiring modification to power it is still working!

The Delta-Q charger is flowing 17.2 amps:

PB110032 1121 start.JPG



Went out at 5:30 pm, ten bars on the SOC meter and the Charge Status Indicator is on solid:

PB110054 1736.JPG



And the green light on the charger is on solid:

PB110057 1736.JPG



Pack voltage is 58.7 volts and no charge current flowing:

PB110049.JPG



More information overload from the BMS program: :D

Fifth time charging was successful. :thumbsup:

--------------------

I decided that I want the LOC back in the dash so the hour meter is visible. ---------------------
--------------------------------

Put the LOC meter back in the original location, will probably disconnect the red LED battery LOC, since it is not accurate with the new Li-ion batteries:

-----
Checked the wiring diagram:

Unplugged it and pushed out the three connectors for the Level Of Charge meter:

PB240002.JPG



Put rubber tubing over the connectors and taped with electrical tape and plugged it back together:

PB240004.JPG



The key is on and the red LOC LED is off, yea!:

PB240009.JPG



Now it is just a Hour Meter, yea!:

It has been two weeks since I charged the Voltronics Lithium-ion batteries, the relocated SOC meter was showing 2 bars again, just like last time:

PB110039.JPG



And 191.4 on the hour meter

PB240013.JPG



So yesterday after the modification to the LOC meter I unplugged the charger from the Y connection and plugged it in to turn on the BMS. Got a picture of the status before charging:

PB240016 257pm.JPG



Plugged the charger into the Y connection at 3:05 pm. Went out at 9 pm, the Charge Status Indicator was flashing slow, meaning over 80% complete. While I was looking at the BMS data, the CSI went solid green, meaning charge complete:

PB240032.JPG


PB240034.JPG


PB240036 815pm.JPG



Sixth time charging was successful. :thumbsup:

It was two and a half weeks ago that I charged the Voltronics Lithium-ion batteries, the SOC meter is showing 2 bars again, just like the last two times:

PC130005.JPG



And 192.8 on the hour meter equals 1.4 hours of actual run time, mainly going to the mail box and back:

PC130003.JPG



So yesterday I unplugged the charger from the Y connection and plugged in the cord to turn on the BMS. Got a picture of the Live Params before charging, showing pack voltage at 52.5 volts equals 15% SOC:

PC130008.JPG



This shows the voltage of the 16 cells in the pack:

PC130014.JPG



Plugged the charger into the Y connection at 11:20 am, to start charging. Checked the BMS at 1:17 pm, the SOC is up to 34.5%, charge current is 17.4 amps:

PC130017.JPG



Went out to the garage at 7:20 pm,
ten bars on the SOC meter and the Charge Status Indicator is on solid, meaning charge complete:


PC130020.JPG



Pack voltage is 58.8 volts and no charge current flowing:

PC130019.JPG



Seventh time charging was successful. [/COLOR][/COLOR]:thumbsup:

Very cool. I'm about to take the plunge on one of these RangerEVs. Hopefully before spring.

Are you going to post results for each of the 3000 charge cycles those batteries are supposed to be good for? ;)

Prepare to be amazed. :thumbsup:

:D Got to do something to keep the thread active!

As the weather gets colder, I will just plug it in and let it charge without connecting the BMS to the laptop. Sure is nice to have the Charge Status Indicator working now after my wiring modification.
