Toyota Still Believes in EVs

Toyota, as an automotive company, has been the biggest EV pragmatist. Its outspoken and revered leader, Akio Toyoda, has been vocal about his considerations and has raised doubts about the EV push of the industry his company dominates.

While their approach to EVs has been conservative, Toyota appears to have been quietly working behind the scenes to perfect its own EV technology. 

Solid-State Batteries are the Future

According to recent developments, Toyota is developing a Solid State Battery (SSB) that can last up to 40 years, which is four times the current lifespan of EV batteries. What is even more impressive is the claim that they are targeting production applications of their Solid State Batteries by 2027 or 2028.

The technology behind Solid State Batteries sounds good on paper; it promises a range of at least 1,000 Kilometers, and is supposed to be smaller, lighter, and cheaper than the current crop we have today.

The Value for Money Option

Keiji Kaita provided insight on its upcoming SSB during the recently concluded Japan Mobility Show (JMS), Car Expertreports. 

Kaita is the president of Toyota’s Carbon Neutral Advanced Engineering Development Center. He was quoted as saying from the get-go, SSBs might cost more to produce in the current technological climate, but they are, of course, working with their supplier to properly integrate the technology into a more affordable package in the long term. 

Furthermore, Kaita also claims that the SSBs will most likely outlast the rest of the car itself, allowing for the opportunity to swap out batteries, which will, of course, offer greater value for money to each owner. 

Staggeringly, Kaita went on to say that the target is to ensure 90% battery capacity and condition by year 40 of the lifespan. Last October, Toyota decided to collaborate with Sumitomo Metal Mining, which will help in the production of cathode materials for the SSBs. 

Toyota’s realistic approach to EVs has enabled it to properly divert resources to something that could potentially give it an edge in the near and far future.
