Should be easy enough to test this theory.surfingslovak wrote:Many people follow this thread, and if the goal was to be heard, we may have shot way past the target. Although I believe that many folks would find more transparency desirable and comforting, this is a competitive industry. If Nissan was indeed temporarily restricting maximum state of charge during hot weather to help protect the battery, I wouldn't expect to see public disclosure of such behavior. Personally, and based on the few data points we have, I believe that it's happening. This could account for up to 5 - 10% of battery capacity. Again, it's just a guess, and depending on the condition of the pack, it might not be enough to bring the lost capacity bars back come fall and winter. I think virtually everyone on this forum is level-headed, and would like to see this program succeed. Let's approach it from that angle.Herm wrote:They cant afford to damage their global investment.. so expect a reaction soon. I'm sure they are following this forum avidly now.
Take a car that has "lost capacity" and run the car down to 50% SOC.
Park the car in an air conditioned shop and run the shop air conditioner on max to cold soak the car down to 72 F or lower. I would guess 24 hours would be long enough.
After 24 hours of cold soaking. Charge the car to 100% SOC and read the GID number and pack voltage.
