Mustang 240V charging with dead fans
3/24/2019

Charger fans died second time. First was Papst IPC 1154 rated that only lasted 3 years, required charging at 7.5 amps on warm days because it would not cut back agressively enough and would cut off.

Second ones were Delta IPC 1155s that lasted 9.5 years.

Without fans in 56 degree weather inside the garage, after 10 minutes at max 20 battery amps or 8 MPH charge rate it got above 100C and throttled to 16 amps at 107C, 6.4 MPH.

Put a ~18" fan pointed down in the engine compartment and the temperature dropped to 105C and increased to 18A, 7.2 MPH. This might be an acceptable workaround if 120V is also available but it usually isn't. I might try powering the fan on the inverter.

Throttled to 14A or 5.6 MPH and it went to 100C, so the max recommended at 56F. This is pretty linear though so I thought I'd go down in current and see where the temperature stabilized.

12A gave 94C, 4.8 MPH
10A gave 82C, 4.0 MPH
8A gave 74C, 3.2 MPH
6A gave 64C, 2.4 MPH
120V charges at 5A or 2.0 MPH so probably below this.

So assuming linear shift:

56F ambient 14A max 5.6 MPH 70%
68F 12A 4.8 60%
90F 10A 4.0 50%
106F 8A 3.2 40%
It hasn't ever gotten hotter than this.
126F 6A 2.4 30%

Vacaville 3/16/2018

66 miles to Vacaville Journey Coffee, 5/8 tank left, 47 degrees, eco plus mode all the way, 60 mph except once override to pass. No heat.
Around 73 miles at Vacaville Kaiser 19/32 tank left so ~178 mile range, 4.3 mi/wh. But it said 81 miles left, 154 miles. Need 54 miles to get back to work chargers in Rohnert Park plus 25 buffer so 79 could make it without charging. But there are 3 Sema Connect chargers and no one here. One person came up with a plug-in but didnÕt plug in grrr. Need to get a Sema Connect card, but 800 number worked. Charged about 45 minutes, 94 mi range when I left.

4 long gas burning trips in the eGolf since weÕve had the eGolf

1. College tours in April to UCLA, UCSD and Cal Poly. Did not feel like we had the time to charge on our compressed trip, but should recalculate.
2. Cal Poly orientation late July.
3. Backpacking in early August in Desolation; not enough cargo for 4 backpacks but could get topper.
4. Cal Poly dropoff mid-September.

2017-11-30 e-Stang range test Posted on December 02, 2017 16:59:31.

Drove 31.8 miles, 12.1 miles in the morning and 19.7 after work, 30.9 total before the 2.9 min cell voltage yellow light came on. Red light expected within a mile, so estimate 33 mile range. But this involved several miles of steady ~20 MPH freeway traffic driving, and coasting and dropping to 20 MPH at one point since I was hypermiling and no one was behind me, which probably added a few miles compared to driving the speed limit. So count on 30 miles, or 24 miles to keep the pack above 20% capacity.
