AUTOMOTIVE BEV PRODUCTS

BATTERY VENT

The battery installation is a critical component within a Battery Vent (BEV). To ensure optimal performance and safety, a high-quality battery vent system is essential. Our product offers a streamlined design and a simple installation process, while maintaining reliable functionality throughout its lifetime.

BEV Coolant Cap

The best-fitting caps you can find

Electric drivetrains typically operate at lower temperatures and pressures compared to internal combustion engines (ICEs).

This enables the use of a more compact valve structure, as there is no need to accommodate high volumes of steam. Our BEV coolant caps are designed to meet these requirements, ensuring efficient operation and longevity.

Our strategy for future BEV coolant caps:

BEV COOLANT CAP

The best-fitting caps you can find

Electric drivetrains typically operate at lower temperatures and pressures compared to internal combustion engines (ICEs).

Our strategy for future BEV coolant caps:

Simple, robust and functional design

Adjustable pressures

Single-stage overpressure is sufficient

Connection to the interface may not have to be as “strong” – bayonet rather than full thread

Weight reduction (>50%)

Alternative materials

Downsized caps

Caps may be hidden and not freely accessible – marking could be reduced

One O-Ring as standard could be sufficient

Simplified marking

Implementation of standard geometry for filler necks with reduced use of filling guns

Simplified assembly

Better-fitting materials for the complete application e.g. >PP< where additives may not be needed

Similar designs are already familiar and established in some OEM installations. It can be equipped with specific stop features (haptic feedback) and drainage channels above the small O-Ring.

COOLING TUBE

Thermal management is crucial to the efficiency of battery-powered products. Ensuring optimal operating temperatures during use and charging is essential for peak performance. Our tubes do an excellent job in distributing the coolant fluid inside the battery pack.

Conventional blow moulded

Suction blow moulded

Extruded (smooth /corrugated)

Thermo-formed

Quick connectors assembled

Tightness tests according to specification

All extrudable plastic grades can be processed

Design will be adapted to suit the customer environment

Connectors that are already established on the market can be implemented / used

Immersion coolant cap

Keeps your fluid clean

Ensuring that dielectric coolant fluid is free of contaminants is crucial for optimal performance.

Standard coolant caps with pressure exchange functions may inadvertently allow humidity to enter the system, compromising the cooling efficiency and potentially leading to short circuits. Our specialised immersion coolant caps feature an additional PTFE membrane, which effectively blocks humidity while still allowing high air flow values. This ensures that the cooling fluid is protected and kept free of contaminants.
