WASHINGTON March 27, 2016 Reuters (Epoch Times reporter Yushan comprehensive compilation report) The battery pack can be said to be one of the hybrid vehicle undisputed most important part. As you know, hybrid vehicles combine an internal combustion engine and the electric motor power, the two work together. To provide energy for the automotive gasoline engine gasoline fuel stored in the box, and the motor from the different channels, that is, the battery pack for energy.

 

 

 

 

The battery pack stores and provides the necessary energy to drive the hybrid vehicle electric motor. No chemical reaction inside the battery, the hybrid technology will not exist, there would be no hybrid vehicles.

 

 

However, despite the prominence and importance of the battery pack for the hybrid vehicle is self-evident, but they also have urgent need to improve the space. It is yet to overcome some of the shortcomings of the car battery, hybrid technology has become the argument of skeptics. For example, they can not provide enough power, so hybrid cars slow start; battery too, to some extent offset the so-called hybrid fuel economy; materials used in many battery lead is harmful to the environment, contrary to the familiar "green" effect.

 

However, the good news is, this does not prevent the manufacturer R & D efforts to improve the product. It is this ongoing effort to bring technology and advances in terms of material, makes the car battery has been greatly improved in many ways. Here is the hybrid battery has made significant progress in five areas.

 

1) lower cost, the price is cheaper

So that potential hybrid car buyers final decision is the biggest obstacle to replace the battery pack is too costly. The cost of the battery pack is generally about $ 3,000, account for a large proportion of the cost of the vehicle. For fear of battery failure caused by the high cost of replacement battery packs brought, led to many drivers stop to make a purchase of hybrid vehicles not before.

 

However, the price of the battery, the battery and the failure rate, compared with a decade ago has dropped significantly. Simply say that, compared to a decade ago, and now the price is cheaper battery, continuous trouble-free longer. For example, in 2001, the cost of the battery pack in the hybrid vehicle can replace about $ 10,000. Honda has recently replacing the battery price from $ 3,400 down to $ 1,968. In the near future, Toyota also plans to slash the cost to replace the battery pack, and now Toyota hybrid cars to replace the battery pack would cost approximately $ 3,000. In addition, the first-generation Toyota Prius battery malfunction battery replacement ratio is about 1%, while dropping to the second generation of 0.003%.

 

2) lithium-ion battery

Most hybrid cars use nickel-metal hydride battery pack was (NiMH) batteries. Currently, NiMH batteries are a reliable energy hybrid cars, and long life, the price is relatively low. In fact, some of the cost low-power battery pack can be as low as $ 600. Of course, if the demand for greater energy output, its battery costs will rise, and because nickel expensive, cost reduction potential is relatively limited. For high-power hybrid car battery, you must use other battery technologies.

 

Lithium-ion (Li-ion) battery of this type of technology is relatively mature one. Most electronic equipment used by many of us are now using a lithium-ion battery technology. If you have a laptop or MP3 music player, it is likely they are to use lithium-ion batteries. Lithium-ion batteries are small and light, making it attractive in the rechargeable battery market. For hybrid vehicles, with respect to the nickel metal hydride battery, the lithium-ion battery at a lower weight and smaller size provide higher power and energy.

 

Use on hybrid vehicle lithium-ion battery technology still needs further improvement, still to be improved because of its reliability, and its cost is higher than the nickel-metal hydride battery technology. However, if the current efforts in the lithium-ion battery technology continue, you should see a smaller, lighter lithium-ion batteries used in hybrid cars. ◇
