So I have had my MS hooked to a battery tender type device / NOCO G7200
My reasons to do so are detailed here
Any reason not to hook up a battery tender to the 12 volt battery ?
How ever I always had this lingering feeling that NOCO was just cycling through the charging current itself as the charging light would never stay steady red or orange or green [ representing various charging states] but was cycling through red, amber and green at a frequency more than what
- it does with my ICE 12V LAB
- the TB would charge the 12V. [ from the famous graph referenced in the thread of the post above ]
So I listened to the NOCO hooked up to 12V and noted that every time the NOCO cycled through its lights, the car would make whirring sounds esp in the front, the HV connector click, and so I decided to measure range loss as car seemed never to be silent as it was without the noco.
In true [non] scientific way, I chose days that had similar ambient temperatures. I checked range at same time with NOCO off and NOCO on. Garage was opened exactly same # of times letting some outside cold air in.I wish I had the ammeter to compare the current running against time while the NOCO was hooked.
Experiment started on Saturday at 10 PM. I did not hook the NOCO
Saturday 2200hrs @188 miles. NOCO off
Monday 0828 hrs @181 miles. NOCO on
Tuesday 0842 hrs @ 176 miles. NOCO off
Wednesday 0842 hrs @ 175 miles. NOCO off
Thursday 1000 hrs @ 168 miles. [ this night was particularly colder ]
I know the numbers are non conclusive, but when the NOCO is on, the car is never silent for more than 3mins. As the NOCO cycles through its lights, the car starts to whirr with sounds in the front and I can hear the high voltage connector click.
This would be a good experiment to run if some one has NOCO or any other battery tender device and Tesla Fi service [ I do not have TeslaFi]
Thoughts ? Criticisms ? Ideas ?
