F1 Filter Dirt Devil
Better Place and Renault reveal the processes of development and testing of Fluence ZE in the research center of the electric car the company has in France. Test the resistance against weather conditions, active and passive safety and try to find possible failures before they reach the stage of mass marketing are the main targets. One of the first test is to check the reliability of water penetration into the passenger compartment and the electrical resistance of the external fluids. As we all know, water and electricity are not very compatible, especially when it comes to a power almost double that a house, 400 volts, so that the resistance of the battery in the rear of the Fluence against water penetration must be total. To ensure that the car is really waterproof, Renault Fluence has tested dozens of times during two consecutive weeks in a line of 60 meters in length, with a water depth of 8 inches and a sprinkler system throughout the stretch. You should also check the correct f1 filter dirt devil durability of the carrier. The vehicle has circulated an artificial tunnel of 350 meters, which is full of dust, f1 filter dirt devil and stones. This dust can clog air filters Fluence cab and prevent proper ventilation. This test can be taken for good when you walk at least 200 kilometers of tunnel dust for an estimated period of six weeks. Torsion tests have two tests in two different stretches of track which examines the strength of the chassis of Fluence to significant distortions. The length of each track is 150 meters, the first is the spread of a series of bumps on the surface at regular intervals and heights, both on the right and left, which cause an agitation of the extreme occupants. The test was repeated at least 100 times to 20 km / h to see the reaction of the car's suspension and chassis. The second track is paved with stones which causes a constant tremor in the vehicle. Measure the length, structure and number of boats that causes the test to verify the correct functioning of the suspensions and check for possible distortions caused by vibrations. Like the torsion test, this is repeated 100 times. The vehicle also undergoes an overhaul for a balanced performance in cornering. The weight balance front-rear axis is ultimately a 50% -50%, thus improving the performance of its diesel equivalent. Then there are lab tests to check electrical currents of electromagnetic radiation effects on components of the vehicle. The EU states that the car has no problem with a field strength of 30 volts per meter, but Renault has extreme range tests with a much higher, between 50 and 100 volts per meter. While the vehicle is on a roller platform 50 km / h, this tour from different directions to see that strong electromagnetic radiation does not interfere with vehicle components and continue to operate without problems or disorders. Also measured the electromagnetic radiation can emit their own electric car in the passenger compartment and check that does not endanger the passengers. This activity is not performed regularly in vehicles, it is not required by European safety standards. However, due to the sensitivity of Israel with this possibility, an Israeli expert was invited to Renault center for numerous electrical tests. It was discovered that the vehicle does not emit dangerous levels of electromagnetic radiation that affect the cabin. Finally, the crash tests performed, paragraph already mentioned in a previous post. In these, the Fluence perfectly enduring a simulated rear crash with a vehicle 1. 800 kilos in weight to 50 km / h. The battery was intact as shown in the photographs. The photo shows the battery platform with a board that runs around the perimeter. That is the weakness of the design where water can enter. While the board is required to make the battery "changeable". The aging of the board is what can be a problem of sealing against water splashing below. . . .
