Nissan Completes All-Solid-State Battery Testing, Aims for Mass Production and Low-Cost Bidirectional Charging by FY2028

Nissan Motor has completed performance validation testing for a prototype all-solid-state battery pack designed for battery electric vehicles (BEVs), featuring a 23-layer stacked cell structure. Previously, in 2025, Nissan achieved the required performance benchmarks for individual solid-state cells needed for commercialization. Under identical volume constraints, this solid-state battery offers twice the energy capacity of conventional lithium-ion batteries, potentially doubling EV driving range and enabling high-power fast charging that reduces charging time by two-thirds. Nissan plans to launch a new bidirectional vehicle-to-home (V2H) power supply device in 2028, allowing electric vehicles to serve as mobile energy storage units to power homes. Current market offerings for similar devices cost around 1.5 million yen (approximately USD 9,450). Nissan stated it will significantly reduce the cost of its new device to make it more accessible to average households, though specific pricing has not yet been disclosed. Company executives noted the device has extremely low mass-production costs and aim to enable vehicle-to-grid (V2G) electricity sales as early as 2030. In the realm of software-defined vehicles, Nissan will deploy its proprietary in-house vehicle software platform this fiscal year, leveraging vehicle-collected data to automate software iteration and development, laying the groundwork for the introduction of AI-powered autonomous driving features in fiscal year 2027. Additionally, Nissan plans to equip its vehicles with an AI companion that integrates users’ travel schedules and in-cabin conversations to deliver intelligent navigation and multi-scenario assistance. According to its long-term strategy, approximately 90% of Nissan vehicles will feature AI-driven autonomous driving capabilities in the future.
