EV46 went for its first real drive around the neighborhood the other night. Sorry for lack of updates. Will try to back fill with some of the work that has been done.
Postmortem:
What went well:
It worked. Drove a few loops around my house and then up to the local store and back.
It feels quick even at 50% throttle limit.
Everything stayed in place.
What could go better:
All wifi based telemetry failed since it had been configured to talk to the house Wifi. I’ve ordered a LTE Wifi access point to add to the car to create a stand alone car network that should be able to failover between house wifi and LTE for uplink.
Jerkiness at very low speed. Others have reported the same, no solution right now.
Desperately need an alignment. Steering wheel about 45 degrees to the right to go straight. This caused the signals to not auto cancel.
No heat. Getting a 12V defroster from Harbor Freight to keep windows clear and the heated seat should keep me warm for now.
High effort at low speed from manual steering. Will eventually install Volvo Electric Power steering pump.
APM cooling fan is very loud. Will try sending a PWM signal to the MOSFET controlling it to see if I can control the speed. I can repurpose one of the T15 pins on the battery controller.
Occasional DSC flashes. Will look at CAN logs and may need to send more/better data on CAN.
Tach bounces around when not moving. It seems to settle down once RPM is actually > 750.
Hood is now stuck shut. Will have to see if I can get it open from underneath.
Oil pressure light comes on and eventually goes out on its own.
No monitoring of temp of MG1/MG2 and no cooling. Need to change the bias resistor. New resistors have been ordered. Inverter warmed up from 10C to 24C during drive. I have the cooling loop from a Prius ready to go in.
