Toyota, Mazda Testing EV Battery Energy-Storage System

Toyota Motor Corporation (Toyota) and Mazda Motor Corporation (Mazda) said today that they have started field tests of Toyota’s Sweep Energy Storage System at Mazda’s Hiroshima Plant in Hiroshima Prefecture, Japan. The system rapidly switches each battery’s power flow on and off, even when new batteries are connected to degraded or different capacity batteries.

“For the tests, the power system at Mazda’s headquarters campus, the only power generation system operated by an automaker in Japan, and Toyota’s system that uses batteries from electrified vehicles will be connected through their respective energy management systems. This will enable the verification of stable, high-quality, and efficient charging and discharging. In the future, the storage system will be used to regulate power supply and demand from renewable energy, which fluctuates depending on weather and time of day, contributing to carbon neutrality,” the companies said.

Mazda Japanese BEVs to Adopt North American Charging Standard

Mazda Motor Corporation (MMC 7261.T)* today announced that a deal was reached with embattled Tesla (NASDAQ: TSLA) to adopt the North American Charging Standard (NACS) for charging ports on the company’s battery electric vehicles (BEV) launched in Japan from 2027 onward. Earlier this year, Mazda said that it will build a new module pack plant for automotive cylindrical lithium-ion battery cells in Iwakuni City, Yamaguchi Prefecture, Japan. The new plant will produce modules and packs of automotive cylindrical lithium-ion battery cells procured from Panasonic Energy Co. The completed battery packs will be installed in Mazda’s first battery EV that uses a dedicated EV platform and will be manufactured at Mazda’s Hiroshima plant. The annual production capacity is planned to be 10 GWh. This could see a U.S. export version, but there’s the ever-changing Trump trade barriers in play. The former Auto Alliance joint venture in Michigan is now a Ford Mustang plant and given Mazda’s strained relations with Ford, as well as Ford’s own struggles with Trump tariffs, it’s a highly unlikely source of Mazda BEVs in AutoInformed’s view.

Tesla itself presents another problem for U.S. sales, AutoInformed opines. Tesla said in late April that 2025 profits during Q1 plunged from $1.39 billion to $409 million. This was a drastic drop from analyst guess-timates as Elon Musk’s DOGE chainsaw kicked back on the company and slashed revenue from $21.3 billion to $19.3 billion. Amidst the carnage of lower customer deliveries, lower margins and lower profits, Elon Musk also claimed that he was leaving DOGE behind as his major work there was finished. Musk will only be spending a day or so weekly on the unpopular Trump DOGE executive order. However, the Tesla brand is unquestionably damaged. Tesla links could be highly toxic, the automotive brand equivalent of an EPA superfund cleanup site. Continue reading
