Test a la Volvo Electric Car Collision

If other manufacturers display the latest electric electric car, Volvo is known as a brand that gave priority to security actually shows how to make electric cars are safe. For the electric version of the Volvo C30 displays in the test-crash (crash-test) forward at a speed of 64 km / hr. .

For Volvo, it is important to electrical safety aspects collide. "The tests we did show, it is important to separate the battery from the crushed (crumple-zone) for the same security level with a conventional car. In Detroit, we were the first car manufacturer memperlihatkankepada world, the security level of real electric cars after colliding at high speed, "said President and CEO of Volvo Car, Stefan Jacoby.

Further, the more vigorous the world automotive manufacturers make electric cars because of its efficiency is very high and does not cause pollution. Electric motors used to drive his car four times more efficient than cars with internal combustion engines (petrol and diesel).

About C30 Electricity, according to Volvo, they have to make cars safer. Because the consumer who wants to buy Volvo electric car like the C30, of course, require the level of safety as a conventional car.

Battery and CablesVolvo C30 Power shown is tested for a hit when the battery is fully charged. Tests conducted at the laboratory collision Volvo in early December 2010. Tabrakannya method is also called offset collision with a 40 percent hit the front of the barrier at a speed of 64 km / hr.

"The test results in accordance with our expectations. C30 C30 Electrical same security level gasoline or diesel engine. The front of the changing forms and distribute the collision energy as expected. The battery and cables, part of the electrical system, remain attached (connected) well after the collision, "Jan said Ivansson, Senior Manager Safety Strategy and Reguirements Volvo Cars.

Cars StructureThe structure of the electric car is different from the conventional version. New components to add new challenges to determine the level of safety and security. For example, C30 Power which is designed to explore 150 km to completely fill the batteries must be packaged in particular. The reason, the battery weighs about 300 kg.

All it requires more space than a conventional car fuel tank. Under the front hood, which usually mounted motor fuel, is now replaced with electric motors and control systems are packed with efficient and light weight. It should also be noted, the voltage on the electric car can reach 400 volts, especially the bike.

Based on the research, Volvo separating lithium-ion batteries from the crushed vehicle and passenger space. Pendekatannnya similar to the conventional fuel tank safety. Another challenge is to strengthen the area in front crumbled. The reason, in that section there is a smaller motor.

50 millisecondsVolvo C30 Power Battery installed in the position of conventional automobile fuel tanks and pools. Batteries packaged in large sizes. There are also extra reinforced floor structure to protect the battery. All electrical cables given more protection to obtain the maximum safety level.

The car also has sensors that menggontrol collision fuse. Electricity from the battery can be disconnected in 50 milliseconds, as fast with a signal to activate the air bag (airbag). Equipped with a fuse system which broke the event of a short circuit or short circuit, for example positive wire touching frame or body. .

In a conventional car, the engine helps distribute crash energy from the front. In C30 Electricity, to obtain the conditions, structures reinforced front of the car. It is intended to absorb collision energy because of the additional weight. That's how Volvo make cars safer!
