EV/HEV capacitors

FHC1 and FHC2 series capacitors for electric vehicles/hybrid electric vehicles (EV/HEV) are for use in conjunction with insulated-gate bipolar transistor (IGBT) modules to prevent ripple currents from reaching back to the power source and to smooth out DC bus voltage variations.

The rapid evolution of electrical systems within the automotive industry is challenging design engineers to meet stringent size, weight, cost, performance, durability, and ruggedness requirements. FHC1 and FHC2 capacitors support advancement of these next-generation electronics.

Hard-coating technology for automotive plastics glazing

A hard-coating technology applied evenly on large or complex-shaped automotive windows made of resin can achieve the same level of abrasion resistance as glass and double the weather resistance of conventional plastics glazing.

The technology applies a plasma chemical vapor deposition (CVD) layer to the wet, hard-coat layer, preventing oxygen or water vapor from penetrating and degrading the layer. The CVD layer absorbs the ultraviolet rays, doubling the amount of time before discoloration or degradation begins in the resin.

A plasma CVD pilot plant capable of treating large and 3D molded resin products with a uniform coating of plasma CVD has been developed. Actual-size plastics glazing exceeding 1m², including those with complex curves for back windows, are being treated at the pilot plant. The plasma CVD method achieves abrasion resistance on the level as glass, satisfying Japanese, U.S., and European Union (EU) standards.

Electronic fuel tank venting system

The eVaptive electronically controlled fuel tank vapor venting system can be optimized for any vehicle platform, eliminating the need for automakers to design unique venting systems for different vehicles. Using software to control the transmission of fuel vapors to a charcoal canister while keeping liquid fuel confined to the fuel tank, the eVaptive system can be optimized for all driving situations as well as stationary and refueling modes.

In a traditional fuel tanks, optimal vapor venting positions are at the top of the tank where vapors accumulate. eVaptive system vent points can be opened and closed for optimized venting via an actuator system. Liquid fuels that enter the vent tubes are routed to a central liquid trap and drained back into the fuel tank.

The actuator system is controlled by a computer algorithm that minimizes fuel carryover to the interior liquid trap in all situations and controls the fuel level during refueling. It also can be used to mitigate the spillover that sometimes occurs when filling a tank to the top.
