The 2014 Nissan Leaf uses a lithium-ion battery pack with a capacity of 24 kilowatt-hours (kWh) as its main energy storage for the electric drivetrain.
Battery type and capacity
The Leaf’s energy system is built around a rechargeable lithium-ion (Li-ion) battery pack. In the 2014 model year, this pack was rated at 24 kWh, providing the core power for the vehicle’s electric motor and driving range in typical conditions.
Key facts about the Leaf’s battery are summarized below:
- Battery type: Lithium-ion (Li-ion) battery pack
- Installed capacity: 24 kWh
- Manufacturer/supplier: AESC, Nissan’s long‑time battery partner
The 24 kWh Li-ion pack is designed to balance energy storage with weight and efficiency, helping define the Leaf’s EPA-rated range for that year and supporting its charging options, including home AC charging and CHAdeMO DC fast charging where equipped.
Notes on chemistry and sourcing
In 2014, Nissan sourced battery cells for the Leaf from AESC, a joint venture historically involved in supplying Nissan with lithium-ion cells. While the overall classification remains lithium‑ion, exact cathode chemistries can vary by supplier and generation, so the emphasis for the 2014 Leaf is on lithium‑ion technology and the 24 kWh capacity rather than a specific cathode formulation.
Impact on range and charging
The 24 kWh pack is the limiting factor for the Leaf’s driving range in 2014. Range varies with driving style, climate, and terrain, but the EPA estimated range for a 2014 Leaf with the 24 kWh pack was in the mid‑80s miles on a full charge in typical conditions. The car supports multiple charging options, including standard on‑board charging for home AC charging and CHAdeMO DC fast charging where equipped, which can help reduce downtime on longer trips.
Summary
In short, the 2014 Nissan Leaf relies on a 24 kWh lithium-ion battery pack, manufactured for Nissan by AESC, as its primary energy source. This battery defines the car’s usable range, charging capabilities, and overall efficiency for that model year.
