Volvo Electric Car Successfully Develops With Mileage 1000 KM For Once Charging Battery


Volvo makes a new step with electric car development project "Range Extender" that is able to travel a distance of 1,000 km. This project conducted a Swedish car company because of the limitations of electric cars currently cruising ability is limited. Range Extender is the electric cars equipped with gasoline engines (motor fuel).

According to Volvo, the project received assistance from the Swedish Energy Agency and the European Union. For these three combinations Volve develop concepts and technologies expected to be conducted a trial in the first quarter of 2012.

"This suggests we become more focused in the development of electric cars. During the electric car has limitations, namely the price and size of the battery charge. As a result, be very limited mileage, depending on battery type and size. With the Range Extender, electric cars could effectively increase the distance thousands of miles, but can emissions below 50 g / km, "beber Derek Crabb, Vice President of Power Train Engineering Volvo Car Corporation.

The development brings together three leading technologies of different technologies, 3-cylinder gasoline engine assist electric motor turning the front wheels. All are equipped with a brake energy concept renegeration or brake energy regeneration.

Gasoline engine used can also be given the intake of ethanol (E85). Two concepts tested on the Volvo C30 Electric. For this Volvo must make modifications include reduced battery size so that the petrol engine and fuel tank could be installed without creating new problems.

Concept I: Relationship Series
Using an electric car the Volvo C30. For this use 3-cylinder gasoline engine powered 60 PS (945kW) placed in the rear trunk. Gas tank capacity of 40 liters.

Machine connected to the generator 40 kW. The resulting power is used to rotate the electric motor with a power 111 PS or (82 kW). Penggemudi can also select and use a generator to charge the battery.
In this way, the mileage is also increased when the battery is used to run the car. The total combined mileage is 1,000 km. If only Relying on pure battery energy, about 110 km.

Concept II: Parallel Relationships
Cars get power from the 3-cylinder engine placed behind the gas tank is also 40 liters. The difference with the first draft, this version of the power source is connected in parallel. It is used for turbo 190 PS petrol engine working rotating rear wheels through a 6-speed automatic transmission.

In this way, the efficiency of cars on the highway when it accelerated better. Because the power cars rely on electric power from batteries, gasoline engines are also generated through the generator. For the 40 kW generator is used.

Motor electric motor that is used to produce power 111 PS (82 kW). The second source was the driving force when combined will produce 300 PS and is expected to sprint from 0 -100 km / h in 6 seconds. Range Extender 1000 km, while the battery is only 75 km.

Concept III: V60 Parallel
In this concept, the whole package drive is the front (engine room). The electric motor is equipped with a 111 PS turbo gasoline engine that produces 140 kW of power, transmission otomatid 2-stage and 40 kW generators. Power from the gasoline engine drive the front wheels through a transmission and recharge the batteries when needed.

Up to speeds of 50 km / h, the car always use electrical power. Gasoline engine will work at high speed. In addition, the gasoline engine is also tasked to charge the battery when its energy is below the specified limits.

The battery is placed in the rear trunk and produces mileage of 50 km (energy from the battery alone). Larger tank capacity, 45 liters and is designed to use gasoline and ethanol. Total mileage of 1,000 km.

"Through three projects allows us evaluate the various possibilities Range Extender. Among other electric car C30 and V60 Plug-in Hybrids. The goal, pressing the carbon dioxide emissions without
compromising the needs, comfort and practicality of using the car, "says Derek Crabb.

Volvo is the most complete car manufacturers perform various tests on vehicles made, especially the security aspect. Well, regarding the company's intention to produce electric cars, namely C30 Electric, various tests were carried out.

One of the interesting tests and greatly affect the performance of the battery is cold temperatures. For that Volvo electric car test at minus 20 degrees Celsius. Apparently, according to the company, which made electric car can operate smoothly.

Described, the test temperatures below zero do because Volvo apply the same test criteria with conventional cars it makes. Especially for electric cars, some new test methods were developed so that part is tested to 200 items.

"We must ensure, C30 Electricity still works fine when run, parking and charge the battery on a variety of conditions, from normal to very cold temperatures and hot. Northern Sweden is the most fitting place to do the tests below zero degrees, "said Lennar Stegland, Director of Volvo Cars Special.

Volvo C30 tested with three temperature control system. First use of heating and cooling for the passenger. Second, the use of cooling and heating for the battery (if needed). Furthermore, the electric motor and the "electronic power" or electronic control cooled using water.

Bio-Ethanol Heating
In this test, Volvo says, managed to create innovative solutions, which makes heating without sacrificing battery performance (mileage). For this, Volvo uses bio-ethanol heater mounted on the car.

Tank used to carry 14.5 liter bio-ethanol.
Utilizing these heaters can also electricity from the battery. In electric mode, use immersion heaters, which warm air in cold temperatures. "Motorists can memogram and control the temperature control unit in accordance with the conditions of his journey. Heating ethanol is the basic mode. In this way mileage vehicles with batteries farther away. For short distances, can operate the temperature control system to obtain electrical energy from the battery, "explains Lennart Stegland.

Battery charging system with no wired or wireless (wireless), it could be without plugs or stekker for hybrid electric cars and plug-ins, car manufacturers are increasingly in demand world. If previously, Toyota has been proclaimed in collaboration with WiTricity (U.S.) to develop a wireless charging system, now turn to Volvo in collaboration with the Belgian company.

This method is considered more comfortable and enjoyable. Because the owner did not bother rolling up the cable car after filling or manarik when going to plug it into the socket. The latest version - is actually still in the stage of development - which will be filled car parked on the plate battery charger (charging plate) that is hidden under the floor or road surface.

Wireless charging developed in collaboration with Volvo Drive Flanders from Belgium - the system induction. With this system, electrical energy is transferred from the source to the car charger without cables. In this way, changes or modifications to the charging system in the car.

"The main target should be fun electric car owners," explains Johan Konnberg, project manager of the Division of Special Vehicles Volvo Car Corporation. In this project Volvo C30 uses electricity to dimofikasi first filling the system.

How it Works inductive charging, the charger plate implanted under the ground, eg below the surface of the road to the house or in the garage. Charger plate consists of a coil that generates a magnetic field when energized by electrical current.

Well, when the car is parked on it, the energy of the plate was transferred to without physical contact to coil "puller" induction on the car. Flows transferred in the form of alternating current (AC).
Later in the car, an electric current is converted into direct current (DC) through a converter to charge the battery. Special to the Volvo C30 Electric, reaching 24 kWh battery capacity, takes about an hour an hour and 20 minutes for full charge.

Added, Volvo will send 250 electric cars to selected customers in Europe in the second half of this year. This is a step to accelerate the use of electric cars to choose!
