Battery Pack
At the heart of this electrified Jeep is a 400-volt 17-kWh nickel manganese cobalt battery pack consisting of 96 lithium-ion cells. To protect the batteries without impinging on the Jeep’s off-roading prowess, the pack gets mounted beneath the rear seat to protect it from the elements. Engineers redesigned the seat to create space for the batteries, and the seat bottom flips up for access. The Li-NMC battery pack is mounted in an aluminum housing fitted with a dedicated heating and cooling system to keep the batteries at optimum operating temperature. All high-voltage electronics that connect the battery to the powertrain are sealed and waterproof, ensuring that Wrangler can still traverse up to 30 inches of water without any risk of a short circuit.
