Nissan has met key performance goals for a prototype all-solid-state battery pack for electric vehicles, bringing the company nearer to its aim of starting mass production in fiscal 2028.
The Japanese automaker disclosed in a technical briefing, as reported by Nikkei Asia, that it has successfully tested a solid-state battery assembly comprising 23 stacked cell layers.
This follows an earlier step in 2025, when the carmaker said its prototype cells had achieved the performance standards needed for commercial use.
Nissan said the solid-state battery can store twice as much energy per unit volume as a conventional lithium-ion battery of the same size, which would allow electric vehicles to travel about twice as far on a single charge.
It also said the battery supports high-output charging, cutting charging times by roughly two-thirds.
Alongside the battery work, the company has developed a bi-directional charger that it plans to launch in 2028.
The charger is intended to allow electric vehicles to feed electricity into homes.
Current bi-directional chargers sell for about Y1.5m ($9,437).
Nissan said it plans to price its product well below that level, though it has not provided a specific figure.
The carmaker also said it plans to let charger users sell excess electricity back to the grid from around 2030.
On the software side, Nissan will roll out a proprietary platform for software-defined vehicles within the current fiscal year, designed to support automated software development using data generated by its vehicles.
The same infrastructure is intended to underpin AI-driven autonomous driving from fiscal 2027, together with an “AI-Partner” function that draws on driver schedules and in-car interactions to assist with navigation and related tasks.
Nissan has set a goal of equipping around 90% of its model range with AI autonomous driving capability.
The company has framed these initiatives under a strategy it calls 'Mobility Intelligence for Everyday Life', reflecting a shift towards a customer-focused direction.
As part of its Vision event held at its global headquarters in Japan, Nissan also unveiled an all-new, all-electric version of the Juke, which it describes as a significant step in its electrification push in Europe.
