Hybrid / battery drive
Fuel tank isolation valve (FTIV)
The FTIV closes the tank when a hybrid vehicle is driven purely electrically to reduce emissions. It controls the tank pressure and regulates the adjustment of the pressure relief of the fuel tank, which is necessary directly before refuelling plug-in hybrid vehicles.
Optimum battery temperature control in electric and hybrid vehicles is necessary for long ranges and long battery life. We simulate the flows in the system and thus ensure the optimum distribution of the coolant.
We can use our own concepts or develop them specifically for you according to your specifications.
Battery dryer for e-vehicles
The battery dryer absorbs the moisture inside the battery system to prevent water condensation on cool surfaces.
The high-quality, multi-stage automatic transmissions of e-vehicles require perfectly matched line systems for transmission ventilation. Well-known manufacturers rely on us as long-standing specialists for line systems on their platforms for electric vehicles.
The high storage pressures of up to 350 bar are not the only challenges for fuel cell powered vehicles. The requirements for thermal and media management as well as the protection of the fuel cell stacks against impurities and harmful gases in the air flow also require a high level of expertise.
KAYSER has already developed two products suitable for series production here:
The particle filter filters the smallest particles (180 µm) to ensure coolant flow even through filigree channels in the fuel cell.
The ion exchanger reduces the conductivity to delay the ageing of the fuel cell.
In coordination with Asian suppliers, where high volumes are expected in the next five years, we are already working on further solutions.
