Oil resources are not inexhaustible, the main fuel for vehicles, it will always be replaced one day, although in the process of finding new energy sources, the world's major car companies have developed a variety of new energy vehicles, including fuel cell vehicles, electric vehicles, hybrid vehicles, alternative fuel cars.VGP-BPS12 battery

And because fuel cell vehicles and pure electric vehicles, there are still many problems in terms of industrialization is not currently available only for research, development and demonstration runs. Today, the world's major car companies have already introduced a variety of hybrid vehicles, has introduced their own production models.

Hybrid vehicle is more than two power sources of vehicles, the first Toyota is in a gasoline engine and battery hybrid power system; has developed a diesel engine and battery hybrid, the gasoline engine and a super capacitor hybrid, diesel and super-capacitor hybrid power, battery and super capacitor hybrid, fuel cell and battery hybrid in 2007 Challenge Bibendum appeared on a new hybrid fuel cell and super capacitors, Hyundai launched the Tucson FCEV is a powered by fuel cells and hybrid supercapacitors.VGP-BPS8

Recycle braking energy in hybrid vehicles and pure electric vehicles, energy recovery in a prominent position in hybrid vehicles and pure electric vehicles, require as much as possible the energy use of brake energy recovery, typically use more battery charging to energy absorbing braking energy recovery, the drawback is difficult to achieve short-term battery power, and a limited number of charge-discharge cycle, power charge and discharge is bound to greatly shorten the battery cycle life, would bring the cost increase. The super capacitor is a capacitor between the battery and the traditional one between the energy storage device, electrolytic capacitors have a much higher than the energy density (specific energy) and much higher than battery power density (specific power), for used as a source of short-term power output. With high specific power (power output per unit mass W / kg), once more the advantages of energy storage, can greatly increase the hybrids, pure electric vehicle driving range, and can auto start, acceleration, hill climbing to improve the mixing effect at the time electric vehicle motion characteristics.DELL Latitude E6510 Battery

Hybrid battery power for use when accelerating or climbing to conduct a large current discharge, slow or fast when charging downhill to achieve braking energy recovery, required battery with excellent high rate charge and discharge characteristics of fast and long service life and stable, but the implementation of large current charging and discharging battery will shorten its life. The super electrochemical capacitor, said capacitor, the stored energy of a large, light weight, multiple high-current charge and discharge, the capacitor capacity, charge and discharge, long life, fast charge and discharge, in -40 ? -70 ? Working range However, the lack of super capacitor is lower than the energy, the battery is only 1 / 10.ACER AS09D34 Battery

In the fuel cell and super capacitor hybrid car, when the vehicle start, the use of super-fast discharge capacitor, Er Shi auto start; when the normal working state, the fuel cell to work, the excess power to electric motors; in vehicles acceleration and hill, by the fuel cells and super capacitors also work; in slow, downhill, braking, absorbed by the super capacitor braking energy recovery.

As the fuel cell car fuel cell to reach operating temperature have a certain time, and super capacitor can be used as fuel cell vehicle starter, and fuel cells can quickly reach operating temperature, so fuel cells and super capacitors are complementary, is an ideal hybrid mode, the direction of development is one of the hybrid. Very suitable for the use of cars and city buses. Which fuel cells and super capacitors documents cars and city vehicles frequently encountered in large cities, traffic lights, stop and start frequently, deceleration, braking situations suitable for use as auxiliary power super capacitors. And the super capacitor cheaper price than a lot of file-ion batteries.Dell Inspiron E1505 battery
