New energy vehicle technology reserve -Lithium - Ion Battery Equipment

Who has the strongest technical reserves for new energy vehicles -Lithium - Ion Battery Equipment

Who is the strongest in the technical reserve of new energy vehicles? This question, the names of several players immediately appeared in my mind: Toyota, GM, Nissan.

Toyota: A player worthy of respect

Toyota, as I said, is a fully prepared player. One of the first automakers to explore new energy technologies in the 1990s, almost single-handedly, promoted the worldwide popularity of hybrid vehicles. In January 2017, Toyota's global sales of hybrid vehicles exceeded 10 million.

With its deep understanding of hybrid technology, Toyota can almost easily cut into pure electric models and hydrogen fuel cell vehicles, so when it comes to battery technology reserves, Toyota must be one of the best in the big factory.

Tesla is likely to bet its future on photovoltaic cells. It is true that Model 3 uses higher-energy nickel-cobalt-lithium batteries, but it is estimated that all of Tesla's efforts since its establishment have been in the present, and there is no room for it. What energy is reserved, I feel that what you see is what you get, and even a bit overdrafts the future, so it is not appropriate to talk about technical reserves.

Such as Toyota, if you don’t make a shot until the time is right, you will be considered a big reserve. Toyota’s new energy technology route reserve can be regarded as a representative of the technology reserve in Japan’s national strategy, so it can’t be weak, after all, it can’t be. miss.(Lithium - Ion Battery Equipment)

GM: Toyota in America

From 2010 to 2015, General Motors received 661 U.S. patents on battery technology, second only to Toyota's 762 U.S. patents, according to the latest data provided by the U.S. Patent and Trademark Office, Reuters reported.

Plus, there's the fact that the world's first electric car was produced by GM. In 1990, the GM Impact concept car made a sensation all over the world. In 1996, the EV1 designed according to Impact was the world's first mass-produced electric car.

The Volt, released in 2007, is the world's first mass-produced range-extended hybrid car, and it has been sold in the United States and other places since 2010. Speaking of this, it is quite interesting to think of Toyota's mix-up, and through strict technical patent blockade, it is quite interesting that the German department has to choose other paths when the EV turns. later.

In terms of integration, the second-generation Voltec deeply integrates the motor controller and electric drive system, which can reduce joints and wiring harnesses, reduce costs, and improve the safety of high-voltage systems.

In terms of compatibility, Voltec's EVT electronically controlled intelligent continuously variable transmission controls the cooperation of two sets of clutches and double planetary gears (Toyota THS has only one set of planetary gears, and has set up strict patent protection for this, so the peers can only High-dimensional competition), produce a variety of power distribution and output methods, form a variety of ratios of engine output and motor output superposition, can realize pure electric (Blot), extended range (Buick VELITE5 extended range hybrid), plug-in hybrid (Cadillac CT6), hybrid (Buick LaCrosse hybrid) and other drive forms, with the application of multiple models and the increase in sales, the cost of the entire part will be greatly reduced, such as molds, production lines and research and development costs will be greatly reduced. Accelerate the popularization of marketization.

Nissan: Leaf in hand

The reason Nissan appears in this "Intuitive List TOP3" is that the Leaf is currently one of the best-selling electric cars in the world.

Nissan's battery technology accumulation does not seem to have a special reputation. It may be because they are only the second in the industry. The first is Panasonic. Yes, Tesla and Toyota have chosen to cooperate with Panasonic, the world's first battery.

Nissan and NEC jointly established AESC (Automotive Energy Supply Corporation) in 2007. After several years of development, the AESC market share reached 21% in 2014, second only to Panasonic. In 2017, Nissan sold AESC to Jinshajiang, China, and began to choose battery products from external suppliers, such as LG and CATL.

Making batteries is a labor-intensive and expensive work, and the technical route of batteries is also changing. For example, AESC is making lithium iron phosphate batteries. After 2013, this road has slowly gone downhill, and everyone is engaged in ternary lithium. battery. Therefore, if the OEM wants to develop its own batteries, it really needs to be fully prepared and switch tracks at any time - for example, solid-state batteries, hydrogen fuel cells or something...
