Nissan, in collaboration with JVCKenwood Corp. and 4R Energy Corp., has introduced a portable power source that utilizes reclaimed modules from old Nissan Leaf electric hatchbacks. This innovative approach aims to provide a second life for used high-voltage EV batteries, contributing to sustainability efforts in the electric vehicle industry.
Key details about the portable generator include:
- Composition: The portable generator weighs approximately 32 pounds (14.4 kilograms) and incorporates two modules from first-generation Nissan Leaf batteries.
- Price: It is priced at $1,170 (170,500 yen) in Japan.
- Outputs: The unit features two high-power outputs, two USB-A ports, two USB-C ports, a 12V socket, and a solar power input.
- Capacity: Specific capacity details were not provided in the report.
- Development: A prototype of the consumer battery generator was initially released in April 2022. Subsequent development efforts aimed to make this prototype a viable mass-produced product.
- Battery Potential: A first-generation Nissan Leaf battery module was rated at 64 amp-hours (Ah) when new, potentially resulting in a total capacity of 128 Ah for a two-module setup. This translates to around 28.1 kilowatt-hours (kWh) at a nominal voltage of 220V or 14 kWh at a voltage of 110V.
- Longevity: Nissan has previously stated that Leaf EV batteries have the potential to outlast the vehicle by up to 12 years, considering the vehicle’s 10-year average lifespan. This means that high-voltage batteries can continue to serve for a total expected life of 22 years, either in the original vehicle or in other consumer tech applications.
- Leaf Sales: The report mentions that over 650,000 Nissan Leaf units have been sold worldwide since the model’s debut in 2010.
While the specific capacity and detailed technical specifications of this portable generator remain undisclosed, this initiative demonstrates an innovative approach to repurposing used EV batteries and extending their service life. It not only contributes to sustainability but also showcases the versatility of EV batteries beyond their initial automotive applications.
The broader adoption of such initiatives could help reduce electronic waste and enhance the overall environmental footprint of electric vehicles.
