Lithium Ion Battery
The Nissan Leaf features a lithium-ion battery with a capacity of 24kWh, 30kWh, 40kWh or 62kWh.
The battery is passively cooled and includes a built-in battery management system (BMS), also known as the Lithium Battery Controller (LBC).
Variants edit
| Capacity | Usable | Found in | Cell configuration | Cell type | Mass | Notes |
|---|---|---|---|---|---|---|
| 24kWh | ZE0 (2011-2012) | 96s2p | AESC 32.5Ah pouch cell | 294kg | Incompatible connector and CAN messages; requires an active adaptor to use in newer models or vice versa | |
| AZEO (2013-2016) | ||||||
| 30kWh | AZEO (2016-2017) | 96s2p | LG Chem 43Ah “lizard cell” | 315kg | ||
| 40kWh | 39kWh | ZE1 (2018-2024) | 96s2p | AESC 56.3Ah pouch cell | 303kg | |
| 62kWh | 59kWh | ZE1 e+ (2019-2024) | 96s3p | AESC 56.3Ah pouch cell | 410kg | As well as being heavier, it is physically slightly thicker than the smaller pack variants |
Lithium Battery Controller (LBC) edit
The Lithium Battery Controller (LBC) physically resides inside the pack, and communicates on the EV-CAN bus. It provides information to the car such as the state of charge (SOC), state of health (SOH), temperature, maximum available power, etc.
Battery replacements and upgrades edit
Nissan Leaf batteries can be swapped between models. Some changes are more straightforward than others. The AZE0 24kWh, 30kWh and the 40kWh packs are completely interchangeable. The 62kWh is heavier than other packs, requiring an upgrade of the springs, and also slightly thicker requiring some physical modifications to the car. The ZE0 24kWh pack's connector is not compatible, nor are the messages sent by its BMS, so interchanging it with other packs requires an adaptor and a CAN bridge.
Stationary storage edit
Many people have used Nissan Leaf batteries for stationary storage (e.g. with a solar system), either as a complete pack or by removing the modules inside. The Battery Emulator project by dalathegreat provides a simple way to connect a complete Leaf pack to many models of solar inverter.
