How much slower is a 16A compare to a 30A EVSE for 6.6kw?

Kia quoted less than 5 hours for 30A. How long does it take to charge the Soul EV using a 16A (~3.3kw)? :|

My 6.6kw Bosch home charging station provides roughly a 25% charge per hour of charge time. Presumably a 3.3kw unit would provide a 12.5% charge per hour of charge time or .. 4 hours vs. 8 hours to a full charge.

Cheers.

FYI, Kia Soul EV should be very similar and slightly faster than "Nissan Leaf Upgrade"

120V @ 15 amp (1.4 kW delivery rate) < 21.43hrs
240V @ 20amp (4.8kW delivery rate) < 6.25hrs
240V @ 40 amp (7.2 kW delivery rate) < 4.55hrs

According to Kia the OBC (On Board Charger) is 6.6KW.

Does this mean a 40 amp charger capable of a higher delivery rate will not be optimal?

There is no use in an EVSE with greater than 32A capability for the Soul EV unless you're specifically trying to future proof. The Soul won't pull more than 32A no matter the EVSE's maximum throughput.

Keep in mind that there are losses in your vehicle battery management system, as much as 400 Watts. These parasitic losses can be attributed to the vehicle power electronics, DC/DC converter, inverters etc. So you are best off buying at least a 4.8kW EVSE for your 3.3kW on board charger or a 7.7kW EVSE for your 6.6kW on board charger.
