Porsche 914 EV Conversion

With the key on, the DC-DC converter light was on; however, when I checked the DC-DC fuse, it was blown. The hazard signals started flickering and nothing would turn on. After pulling over and checking the voltage on everything, the pack was nicely up at 150V but the accessory battery was down to 10.5

I found that the inductive spikes were shutting off the DC-DC converter through the nShutdown pin on the SG3525A and causing craziness in the gate-drive pulse. However, the FET gate pulse is all over the place and the DC-DC converter whines loudly. I then turned on the fog lights, tail lights, turn-signals and reverse lights.

In the process of driving, the brake lights and turn-signals were also on. This is the first time I've arrived home with the DC-DC converter still working! I just drove home from a meeting for half an hour with the headlights on. I'm going to give it a week and see if anything else causes a failure.

Since the DC-DC converter was blown and I didn't want to deal with it, I focussed on some other electrical problems I'd been having. To get at the contacts which turn on the blower motor and fan light, you simply remove the ashtray in the center of the dash all the way (press down on the center clip). This eliminated the 1.5

In the process, the DC-DC converter turned on (indicated by red LED) and then slowly decayed to the off state. The 10 gauge black wire comes from the charger and the smaller yellow wire drives the voltmeter in the cockpit and drives the DC-DC converter. I spent the evening debugging the small sparking issue I ran into yesterday.

I'm also thinking about replacing all the rear bulbs with LED lights to save on 12V current. I might possibly purchase a 12V 20Amp heater for the cockpit, but I don't want to stress out the DC-DC converter too much and a 300 weight polar fleece jacket seems to work fine.

One of the other 914 kit converters questioned why the accessory battery couldn't stay in the original tray, but I decided to remove it anyway and have the accessory battery up in the front trunk near the DC/DC converter. Since this would just be for light testing, I might even be able to get away with cheaper 2/0 welding cable.

I spent most of Friday trying to figure out just what was blowing the DC-DC converter. The opened up DC-DC converter is front and center. I have the oscope covered with cardboard to shield out excess light so I can take pictures of waveforms. Here's my full testbench setup. On the upper left, I have a 156V DC power supply.

In the process of attaching cables to the auxiliary battery, I got a click from the key-switch relay on the right and the DC-DC converter turned on (red light). Okay, we now have all the wires from the fuel compartment with connectors on them attached to the battery or components on the relay mounting board.

Conversely, high coating thicknesses for the electrodes produce a high energy density. Under a venture with the motto “From Road to Grid”, Audi is therefore currently working on a concept to convert old batteries into stationary energy stores. The plate has an integrated primary coil and an inverter (AC/AC converter).

If in addition to normal electric use in homes such as lights and appliances, we charge the PHEV cars at 2 kW at the appropriate times, we could increase the utility factor of the already-installed wires in homes to more than 25%, still leaving plenty of safety margin and capacity. Or their UF=10% to 15%.
