GID • Gary Giddings found on the CAN bus

is not the SOC, it's watt-hours / 80.

• If you multiply "GIDs" * 80, You get the true capacity in watt hours

• In a brand new LEAF, the number of GID = 281

• 240 * 80 = 19,200 Wh

• %GID = 240/281 = 85.4% • Make sure to set Wh/Gid = 80 on ur

To minimize battery capacity loss: • Avoid parking in the sun , try to park in the shade. • Keep the SOC in the 30-40% range as much of the time as

reasonably possible. Charge to 80% or 100% right before you need to make a longer drive.

• Shallower cycling (DOD) of the battery pack when possible. For example, two cycles of 60% to 30% SOC rather than one cycle of 90% to 30% should be better for the battery pack.

• Drive and accelerate more slowly and more efficiently. • Avoid full charging and deep discharging. • Charge your EV at night.
