TOYOTA engineers are studying lithium battery technology. At present, TOYOTA can be more energy safely packaged together, and does not bring additional costs. This means that TOYOTA can better develop the rapid development of the electric car market. Despite rival Tesla and Nissan as early as 10 years ago, began to study the lithium battery technology, but for cost, size and safety considerations, TOYOTA has not been in this area of action. There may be problems with the stability of lithium batteries. Recently, Samsung Note Galaxy 7 smart phones due to the problem of the battery fire and forced to stop selling.
TOYOTA's accession to the development of lithium battery technology is good. TOYOTA has not invested in the development of all electric vehicles, but will be devoted to hydrogen fuel vehicles.
TOYOTA said that the upcoming hybrid version of the Prius Prime will use lithium batteries. Before starting to work on the gasoline engine, the battery power is enough to make the car to reach about 60 kilometers per hour.
Many electric vehicles use nickel cobalt manganese dioxide batteries. This type of battery energy storage more, faster charging, is considered more secure than the lithium battery. However, if there are defects in the design, manufacture and control of the battery, the battery is still likely to overheat.
The Prius chief engineer Koji Toyoshima said, the development of safe use for 10 years, lithium battery car or driving hundreds of thousands of kilometers is a very high requirement. TOYOTA uses additional safety measures for the battery pack, while security is the key to TOYOTA's consideration.
