It could be the best Nissan battery pack ever
The new Nissan LEAF e+ brings significant improvement in battery capacity (62 kWh) and range (up to 364 km / 226 miles EPA).
According to what we know so far, Nissan uses lithium-ion cells from AESC, which are already used to produce modules and packs at the Tennessee manufacturing plant (see video below).
***UPDATE: Nissan has commented on the cell maker, stating:
“LG does not supply any cells for our batteries, both in the US and globally, for either the 40 or 62 kWh battery."
“LG is not a supplier for Nissan LEAF batteries or cells. Nissan manufacturers the batteries for the Nissan LEAF at our battery plant in Smyrna, Tennessee."
The cells seem to be a laminated type and there are 288 of them (compared to 192 in 40 kWh packs), but as you can see, the overall design of the pack is similar. The pack is only slightly bigger and we believe probably slightly heavier (no data here).
“Even with a 25 percent increase in energy density and the increase in energy storage capacity, the LEAF e+ battery pack is almost the same size and configuration as the pack in the Nissan LEAF. Other than a 5-millimeter increase in overall height (16-inch wheels), the car’s exterior and interior dimensions are unchanged.”
The pack doesn't have liquid cooling system, which of course opens the question of
why again how it will handle higher temperatures? Maybe there will be less of a problem as the charging power improved from less than 50 kW to 70 kW (100 kW peak).
