Toyota electric vehicles move towards revolutionary breakthrough: Solid-state battery R&D plan exposed

News on September 20, Toyota Motor recently unveiled its latest generation battery electric vehicle production line and a series of eye-catching new technologies in Japan. The moves are seen as a sign that Toyota is entering a new era of electric vehicle manufacturing as it aims to catch up with its U.S. and European rivals in the EV race.

One of the highlights of the new production line is Gigabit casting technology, which was announced at the Miaozhi factory in June 2023. Giga Casting uses large, single castings to create the vehicle's major structural components to reduce weight, improve structural integrity and simplify the manufacturing process. According to Toyota, they have extensive knowledge in molds, especially low-pressure molding and die casting. The introduction of this technology will significantly reduce mold change time from the original 24 hours to only 20 minutes.

Toyota plans to improve the quality of castings and reduce the number of defective products by applying proprietary analytical technology. In addition, Toyota will adopt EV's new modular structure and automated production methods, which will account for half of the entire production process. The company also plans to make major investments in its factory in Motomachi, Aichi Prefecture, to build a new production line

According to the editor’s understanding, Toyota also released the development route and timetable for solid-state batteries. Currently, Toyota is in a critical stage of solid-state battery development. They have successfully developed a solid-state battery that can enable electric vehicles to travel 745 miles and be fully charged in just 10 minutes. The company aims to bring the technology to market between 2027 and 2028

Under the leadership of CEO Koji Sato, Toyota plans to launch it in 2026 10 new electric cars, aiming to sell 1.5 million electric cars a year. The plan also includes the launch of a three-row electric SUV, which will be assembled at a plant in Georgetown, Kentucky, USA. In addition, Toyota plans to invest an additional $2.1 billion in a battery plant in North Carolina. These moves show Toyota's aggressive efforts to take a leading position in the electric vehicle market
