After a shaky start with battery-powered EVs, Toyota, the world's largest automaker, now believes it has the right path forward. 

They are looking at using four different solutions for their batteries, depending on the model of the car. 

"We will need various options for batteries, just like we have different variations of engines. It is important to offer battery solutions compatible with a variety of models and customer needs," said Takero Kato, president of BEV Factory.

It's great to see that they're thinking this way as "one size fits all" is never a great consumer strategy.
