TENDUR ULTRA ANTI-ABRASION
HIGH-VOLTAGE CONTACT PLATINGFOR LIFETIME HIGH-PERFORMANCE EV CHARGINGThe Demands of Next Generation Drivers
It is often said that the next generation of mobility – offering safer, greener
more connected means of transport – will be characterized by vehicles
running on two types of fuel: electricity and data. However, while safety,convenience, and the desire for ubiquitous connectivity are driving an
increasing number of data-centric, cloud-based vehicles, many consumers,
despite their environmental concerns, are still reluctant to fully embraceelectro-mobility.

Charging Performance – The Role of Connectivity
Charging, and in particular, charging time and the availability of charging
points, is still a major concern for many potential electric vehicle (EV)drivers. In this regard, connectivity technology can play a vital role indelivering the safe and reliable high-power 10 minute / 300 km charging
that would help allay consumer concerns. This starts at the charging inlet.
High-power charging (HPC) involves DC power at currents of 500 ampsand beyond. These high current levels can generate heat that can exceed
safety thresholds, causing the charging apparatus to reduce the rate ofelectricity transfer to the car. Managing these extreme temperatures
minimizes the impact on electrical conductivity and charging performance.
Additionally, wear and tear can occur between a charging station’s equipment and the vehicle itself. Public charging plugs can be damaged byabuse or exposed to abrasives such as dirt or salt. This damage can betransferred to the vehicle’s charging inlet.
One of the best ways to mitigate damage to charging inlets and reduce theoccurrence of extreme heat during high-powered charging sessions is toconsider the quality of the inlet’s contact surface plating. Having the rightsurface technology is critical to maintaining high charging performance forthe lifetime of the vehicle.

TENDUR Surface Plating Protects the Car’s Charging InletTENDUR is TE Connectivity’s (TE) new surface plating developed toprovide abrasion resistance, resulting in continuous high-performancecharging capability throughout the vehicle’s lifetime.
TENDUR plating combines the electrical conductivity of silver with theself-lubricating advantages of graphite particles. The graphite minimizes
abrasion on any part of the contact zone, during mating, to negligible
levels. In addition, TENDUR contact plating retains all the electrical performance properties of alternative silver elements, such as silver-copper,silver palladium, or silver antimony.

TENDUR surface plating comprises
particles of graphite (C) surrounded bysilver (Ag).

Lifetime Charging Performance Assurance
Traditionally, plating technologies for charging inlets are rated to withstand up to 10,000 mating cycles.
However, TENDUR plating has been tested to withstand 50,00 0mating cycles with virtually no contact zone wear,
thereby providing a greater degree of electrical stability for a longer period of time.

The application of TENDUR surface plating to charging inlet contacts helps confirm that abrasion will not bea factor leading to current de-rating during high-power charging sessions. By contrast, lower quality surface
technologies could eventually lead to abrasion damage that could have an adverse affect on charging
performance.
