2.3. Lithium ion (Li-ion) battery

The Lithium ion (Li-ion) battery is charged with the electric power generated by the power generator and/or the regenerative power from the electric motor for driving. While driving, the Li-ion battery provides the stored electric power to the electric motor for driving. Because the engine charges the Li-ion battery when the level of remaining charge in the Li-ion battery is low, the battery does not have to be charged from an outside source like an all-electric vehicle. If the vehicle is parked for a long period of time, the Li-ion battery discharges gradually. To avoid this occurrence, drive the vehicle for approximately 30 minutes at least once every two to three months. Otherwise, the Li-ion battery may be damaged. If the Li-ion battery is completely discharged and the e-POWER system cannot be activated, contact a NISSAN dealer.
