Efficiency meets comfort: New heating solution for hybrid and electric vehicles

The trend towards electromobility is also increasing the demand for innovative heating concepts for vehicles with alternative drive systems. High-voltage coolant heaters from Eberspächer catem are the optimal solution especially for hybrid and large electric vehicles with their own water circuits. Based on tried and proven PTC technology, the experts have now developed the performance and weight optimized third generation. Significantly improved heat transfer between the PTC elements and coolant increases the performance density at zero degrees coolant temperature by more than 30 percent. The product benefits from an electronic control unit that was developed within the Eberspächer Group, and assures efficient energy and heat management. The heaters will be fitted in models from various European automobile manufacturers.

Gasoline particulate filters make gasoline vehicles cleaner

A new level of the Euro 6 emissions standard will come into force for all newly type-certified passenger cars within the European Union in September 2017. Its provisions include a reduction in particulate limits for gasoline vehicles with direct fuel injection engines. Almost one in two gasoline vehicles is fitted with this type of engine. However, this combustion method does result in increased emissions of soot particles. The Eberspächer gasoline particulate filters counteract that effect, filtering the soot particles out of the exhaust gas flow. Using the special filters means the soot particle content in the exhaust gas is well below the legal limit. As a result, the systems conform to the upcoming level of the Euro 6 emissions standard. Eberspächer developed the exhaust system based on the tried and proven technology of the diesel particulate filter. The soot particles are automatically deposited on the porous surface, so greatly reducing emissions.

Safe electric systems for plug-in and mild hybrids

The coasting function is part of the drive concept of hybrid vehicles. The start-stop system turns off the combustion engine not only when the vehicle is at a standstill, but as it is coasting too. Safety functions such as the power steering and brake booster are powered electrically when coasting. When the engine is restarted, they need to be protected. The solution: the Q-Diode 2 from Eberspächer Controls Landau isolates the starter battery from the rest of the 12 Volt vehicle electric system in less than 100 microseconds, so preventing voltage drops as the combustion engine restarts. With approximately 1.2 million switching cycles, the product is ideally equipped to handle large numbers of starts. It switches currents of up to 250 amperes, with no mechanical wear. The Q-Diode 2 is also well suited to use in hybrid vehicles thanks to its patent-pending self-diagnosis system.
