August 10, 2011: This Ford Ranger EV has commuted reliably to work for 18 consecutive days with no problems. Our Goal: 30 consecutive days of commuting. On 8/10, I drove the EV another 13 miles. Afterwards, pack voltage was 150.0 V. State of Charge was ~ 65%. Ambient temperature at charge was 70 degrees F. Still just 6 BMS regulators are communicating.
Started Charge: Turned current to 26.0 Amps for 68 minutes to 171.0 V.
Turned down current to 15 Amps for 6 minutes to 170V.
Regulator #2 and #3 reached 14.50V first. This was the high voltage limit set. Charge time was 1 hour and 14 minutes. .
Final Voltage Cold > 8 hours later 155.3V (next morning).
NEXT: Drive to OEVA meeting downtown is tomorrow. Still working to communicate with additional 5 BMS regulators so that 22 of 24 batteries are regulating. Also, bad regulator is still out for replacement.
