Freudenberg Sealing Technologies develops new Heat Shield to make EV batteries safer
Freudenberg Sealing Technologies has developed a heat shield for use in prismatic and pouch cells with almost no impact on the required installation space. It combines the high heat resistance of a silicone-based elastomer with the high insulating properties of air.Read Now
High energy density, which has been battery developers' top priority, creates a basis for the broad acceptance of electric vehicles. But the more energy is stored in a confined space, the greater the safety requirements. So precautions are essential in case a damaged cell overheats.
Experts call the phenomenon "thermal runaway," and it can cause the temperatures in a cell to rise as high as 600°C. The risk is that the battery's cooling system would not be able to drain the heat away quickly enough under these conditions. If neighboring healthy cells also heat up due to the heat buildup, a chain reaction can result that, in the worst case, could lead the entire battery system to explode.
Freudenberg Sealing Technologies is counteracting the risk with a new development. Heat shields between individual cells are designed so that the heat from a damaged cell remains insulated until it can be drained away. The heat shield has three key characteristics: First, the shield itself consists of a heat resistant material, a silicone-based elastomer; second, it slows the heat transfer between the cells with a waffle-like structure – tiny pockets of air provide outstanding heat insulation. Third, the shield is very thin, with a maximum thickness of just 1 mm. The loss of the existing energy density due to the shield's use is hardly noticeable.
Freudenberg created a new test procedure for the development of its heat shield. It involves mounting samples of the heat shield on a surface heated to 600° C and recording the temperature on its rear side with thermocouples. Series of tests have shown that temperatures significantly under 200°C occur on the rear side after 30 seconds.
"This will adequately protect a neighboring cell against the destruction of cathode material or the separator," said Freudenberg expert Peter Kritzer. "The exact boundary values admittedly depend on a multitude of specific parameters such as the chemistry and geometry of the battery cells."
The way is now clear for the testing of battery modules and systems. Consideration has even been given to the heat shield's mounting. Since the air pockets adhere well to the smooth metallic surface of a prismatic cell – thanks to a suction effect – an individual shield can be precisely position.
It would even be possible to expand the function of the heat shield with additional development steps. If this flexible formed part were extended over the top of the cell, it could enclose and seal the rupture disc located there. In case of overpressure in the battery cell, the rupture disc ensures that the resulting partially toxic gases escape in a controlled way.
New Ford Focus to come equipped with Pothole Detection system
Ford is helping limit the impact of damaged roads for drivers of the all-new Ford Focus by introducing innovative pothole detection technology.Read Now
The system senses when a wheel is falling into a pothole and adjusts the suspension so that the wheel doesn't fall as far into it.
Potholed roads not only make journeys uncomfortable: harsh impacts with severe potholes can also cause damage to a vehicle's wheels, tyres and suspension systems, resulting in hefty repair bills for car owners.
Because the tyre and wheel don't drop as far, they don't strike the opposite side of the pothole as harshly. The rear suspension can respond even faster than the front, with a signal from the front wheel providing a pre-warning to the rear wheel before it reaches the pothole. This all happens in a split second.
"Our engineers are always searching for the roughest roads to really test our suspension to the limit, but more and more we're noticing that the rough roads are finding us," said Guy Mathot, Ford Focus vehicle dynamics supervisor. "Potholes are a problem that isn't going away anytime soon, but with our advanced suspension technology for all-new Focus, we've been able to reduce their impact."
The all-new Focus pothole detection system is a feature of the car's optional Continuously Controlled Damping technology, which every 2 milliseconds monitors suspension, body, steering and braking inputs, and adjusts the vehicle's suspension responses for the smoothest ride quality.
Ford develops its suspension systems using a specially created road at the company's test facility in Belgium, which consists of precise replicas of some of the worst potholes and road hazards from around the world.
Engineers further refine the systems with hundreds of hours of testing on a diverse range of European public roads, monitoring loads and strains with equipment similar to that used by seismologists to study earthquakes.
Hyundai invests in Autotalks to develop V2X chipsets
