WASHINGTON April 3, 2016 Reuters (Epoch Times reporter Yushan comprehensive compilation report) <resumed last week> The battery pack can be said to be one of the undisputed hybrid cars the most important part. However, despite the prominence and importance of the battery pack for the hybrid vehicle is self-evident, but they also have to be very room for improvement. Fortunately, manufacturers are continuing to constantly bring technology and advances in material aspects, it makes the car battery has been greatly improved in many ways. Here is the hybrid battery has made significant progress in five areas.

 

 

 

 

3) new lead-acid battery technology advances

Although the lithium-ion batteries have the potential to replace nickel-metal hydride batteries, but currently used on a large scale hybrid cars still have high prices, and there is reliability problems. Now NiMH batteries may not be cheap, but their costs have further room to fall. Then reduce battery costs and technology in the channel where?

 

 

You may be surprised that the lead-acid battery is to reduce the cost of the battery potential solutions. The reason why this conclusion is surprising, because the material of such batteries is not only very heavy, but also environmentally harmful substances.

 

However, lead-acid batteries have been around for a long time. This battery is a French physicist Gaston Plante invented in 1859. Australian and Japanese researchers on this battery had a long study and find ways to improve. These researchers have invented a so-called super battery. The battery is the use of so-called super super capacitors and batteries to power the car together. The super capacitor can be short for hybrid vehicles provide the necessary acceleration energy without reducing the storage characteristics of the battery.

 

Although the car industry as a whole is concerned is still not particularly willing to lead-acid battery technology used in hybrid vehicle, the battery system does have a cost advantage, a battery may only be $ 1,000 or less, by 2010 some Japanese cars already using this super-cell technology.

 

4) Longer Battery Life

Over the years about the short battery life, and high failure rate rumors indeed it has scared off many potential hybrid car buyers. Many hybrid buyers ask if they will eventually need to replace the battery pack, as well as how long it takes four years? 5 years? Or seven years?

 

The fact is, as car companies to ensure long life and the life of their automobile hybrid battery pack. In recent years this has been a figure of about 100,000 miles (160,934 km) or more. In some cases, the battery quality assurance is generally 8 years or even longer. In other words, if the battery in the car warranty period for some reason fails, automobile warranty remains, including battery, so battery replacement costs remain in the car vehicle warranty, the manufacturer will pay the replacement costs. For example, the 2010 Toyota Prius battery, its quality assurance for 10 years, 150,000 miles (241,402 km).

 

5) lighter

Heavy batteries for environmentally conscious, drivers care about fuel consumption is a huge obstacle. The weight of your car, the more weight your car to drive forward the need for more fuel. That's why people keep reminding you, if you want to save more gas money, put your car trunk or back seat of unnecessary items like it.

 

Of course, researchers also know this problem. Therefore, many researchers have done a lot of research in the weight of the hybrid vehicle battery pack aspects. For example, the Massachusetts Institute of Technology (MIT) research team has found a way to make lithium-ion batteries are lighter, and faster discharge. Lithium-ion batteries to the original question is its discharge rate is relatively slow, the scientists initially thought to be due to the lithium battery materials atom by speed too slow. But the MIT researchers think this may be for some reason nanoscale level slows down the speed of movement of ions.

 

Lithium phosphate coating helps to accelerate the movement of ions, making them easier to quickly reach the battery terminals. New battery materials also terminated the degradation of the battery, which means that compared to the past, manufacturers can reduce a lot of battery size. ◇ #
