Digital battery

Although the hybrid car can effectively reduce oil dependence, reduce emissions of carbon dioxide, but still not enough depth. It is also equipped with two sets of power system, which not only increased the cost of car, the difficulty and complexity of controls, but also the extra weight of the car, which reduces the overall energy efficiency of the car. Therefore, it is only in VGP-BPS2A VGP-BPS9A battery technology has reached a greater opportunity before the break.

 

According to the Department U. S. test reports of energy, gas / diesel to provide energy, only 12.6% eventually used to drive the car, engine wear is 62%, idling, braking and loss transmission of 20%. On the outside the case of an external power supply, energy efficiency hybrid can be increased up to 20%, fuel efficiency is limited space.

 

3.3.1 Running the same distance, the energy of the electric vehicle is 80% less fuel than vehicles over

 

3.3.2 Electric energy efficient vehicles, its advanced performance management

 

While a hybrid can reduce energy consumption and pollution, but, after all, based on the internal combustion engine as the main source of energy, electricity as auxiliary power. With the need for a car equipped with two sets of power system, an economic cost and environmental standpoint, there are more limitations. Pure electric vehicles completely solve the environmental pollution caused by car use and emissions. IBM ThinkPad R52 battery IBM ThinkPad T40 battery

 

The energy efficiency of motor vehicles by 70% ~ 80%, 20% less than conventional cars.

 

Pure electric vehicles are only four components: batteries and management systems, motors, electrical control system, body and auxiliary systems. Compared to cars with internal combustion engine, except the clutch, gearbox, differentials, engine size and weight also significantly reduced compared to internal combustion engines, mechanical systems significantly reduce the weight and the complexity of complex mechanical systems to reduce significantly the loss of energy, pure vehicle efficiency electric energy can be increased to 60% ~ 80%, which is the internal combustion engine 3 to 4 times.

 

Practice control.

 

New power motor, motor control simply by the circuit parameters such as voltage or current controls the torque and rotation, without the need for complicated mechanical support (eg, clutch, box speed, differential, etc.); reduce the weight of the same time, increasing energy efficiency.

Engines with high efficiency and excellent handling properties.

 

Transport operation usually requires a different speed and torque, the operating conditions of internal combustion engines can be changed significantly at the same time to meet the speed and torque distribution. Internal combustion engines need to maintain a high speed by the switch and adjust the speed and torque required for coordination through the transmission and clutch to achieve the torque and speed regulation. For this reason, gas / diesel engine in a very narrow range of speed and torque within the maximum power, usually 10 ~ 20% efficiency. The engine can be started with a load, operation at low speed when the torque is high speed and direction of the adjustment simple and convenient adjustment can be no change of speed and torque, the operational efficiency to 80%. Under the same driving forces, the drive motor smaller and lighter. Such as the Tesla Motors Electric Motor Electric Sports Car is only 52 kg (internal combustion engine up to 400kg) to 100 kilometers of power 12.7kWh, energy efficiency of 86%.

 

Internal combustion engine is running, multiple pistons working together, making the torque output volatility, the training torque fluctuations, and motor drive system runs very smooth, and can achieve rapid control, idling or braking This game was a loss of recyclable energy.

3.3.3 Breakthrough in battery technology needed - there is no universal reason for electric vehicles

 

Because electric cars all the energy of the battery power, the performance of batteries power will determine the use of the performance of electric vehicles.

 

Ease of use.

 

As the battery capacity is relatively limited compared to gas / diesel cars, car less energy, mileage endurance obviously too small. Number charging station is very small, specialized fast Chong Chongdian network is not fully developed, the slow charge time up to 5 hours or more, easily causing inconvenience to users of the consumer experience , pure electric vehicles are not widely accepted.

 

Battery Pack consistency problems.

 

The newly developed lithium-monomers performance ion batteries can fully meet the practical needs, but the battery power required hundreds of single cells used in combination. While maintaining the performance of the cell line so unique, difficult, but also affect the consistency of the battery. Under current conditions of the PA3285U-3BRS PA3383U-1BRS batteries produced poor consistency, resulting in a simple battery life over 2,000 times the battery life of only 500 times. Solution consistency problem depends on the level of manufacturing technology and equipment, upgrading, and intelligent battery management.

 

The higher initial cost of the battery.

 

Limits of process technology, battery low yield, while not large scale application of traction batteries, resulting in production costs of high-power batteries. The performance of electric vehicles cost significantly higher than conventional vehicles, although the long term, much less expensive than the use of electric vehicles, gas and diesel vehicles, but consumers are still reluctant to assume a more cost high initial purchase.

 

State to pay higher oil costs, “allowance” Domestic consumption of oil. A1008 A1012

 

The same configuration BYD F3DM and Toyota Prius, on each of your 80,000 yuan.

 

China’s answer to climb steadily oil prices and increased annual oil consumption, must pay an annual average of about 100 billion yuan on oil imports. If half of them used to subsidize cars low carbon subsidies to 100,000 vehicles per year in China may add 620,000 low-carbon cars. Why do we prefer to pay high prices to buy foreign oil, but refuses to pay more to buy oil money used to develop electric vehicles in China, to promote our automotive clean, new energy technologies promoted?

 

Delivered to China in 2007 accounted for 34% of oil consumption in the field of industrial fuel consumption by 41%.

 

Traditional car manufacturers have no incentive to promote electric vehicles.

 

Before the financial crisis, the traditional automobile manufacturer’s traditional car can generate enough profit to support the operation of the company, the manufacturer has no incentive to manufacture and sale of electric cars. Affected by the financial crisis, various automakers have plunged into economic crisis, have to find new points of growth in profits, while national policies, the new electric vehicles, several manufacturers competing to become the hot investment. I believe the major auto manufacturers and government policy, largely driven by the pace of development of electric vehicles will be accelerated. BATBL50L6 LCBTP03003
