1. what is a brake capacitor?

2. How do they handle L3 charging, any details?

If you order the L3 port then perhaps you can also use it for charging at 6.6kw, with an external charger that sits on the wall of your garage.
The brake capacitor is a backup power supply for the hydraulic braking system so that in the event of total power failure or system shutdown you would still have enough power to stop the car safely. The hydraulic braking system uses a pump to generate boost pressure so you can have reasonable pedal force with disc brakes.

The DC fast charge (technically there is not yet a L3 "standard") is essentially off-board. The car sends a serial message to the off-board charger letting it know how much power to send and when to stop. Yes, if you buy a DC fast charger then you could charge at up to 30kW depending on the limitations of the charger (and the power fed into your house).

I got mine at Mouser, but it was the last one and they are out of stock now.

It's a little bulky, but seems to work ok.

I hope you used ground shipping on that one.

FedEx gave me free shipping because I told them they could use the fast charger en route on their new EV delivery truck.

Come on, EVDRIVER - it would be really irresponsible to ship chargers using an ungrounded method... :P

I did a little Google search for Nichicon and came up with this little tidbit.
Input power of 3.6kW, but the conversion efficiency of 90%, so the output power of 3.3kW. In addition, 90% of the conversion efficiency of the charger in the car at a high level. Chargers internal use of the motor and inverter cooling water into the internal water-cooled. By circulating water around 60 deg c temperature rise suppression circuit.

Thanks Phil, the serial protocol has been published?.. get hold of the connector and you could have a portable DC charger that plugs into an RV hookup and charge at 12kw

Saw this thread this morning again and looked up the part number from the first photo on everythingnissan.com. The charger costs $1,720 list and $1,397 discount price... Interesting...

I would have definitely paid the same again for 6.6kW instead. [sigh] :?
