The research study covers the present scenario and growth prospects of
the global electric vehicle relays market for 2017-2021.
Technavio presents a detailed picture of the market by way of study,
synthesis, and summation of data from multiple sources.

In EVs, relays are largely used in powertrain, battery, charger system,
and interior and exterior system, which include safety features,
security, and comfort features. EV relays are either in normally open
(NO) or in normally closed (NC) state. Most of these relays are used in
conventional ICE vehicles also, except battery, power electronics, and
charger system relays.

Low cost SSR relays

In the last decade, SSRs have attained much penetration and replaced the
conventional electromechanical relays. Owing to the nano and micro
materials and very large-scale integration (VLSI) techniques, the design
of the SSRs have become more reliable, safe, and durable. Also, SSRs
allow fast switching and high switching currents, making it suitable for
high-power rated applications, such as in EVs.

Amey Vikram, a lead automotive
research analyst at Technavio, says, "As the
technology becomes more advanced, the cost to develop and manufacture
the relay also increases. Hence, it is essential that cost reduction and
quality of relays go together. As relays extensively use raw materials,
such as copper, silver, and other precious metals, which are expensive,
a balance must be struck between the quality of the relay and the
overall manufacturing cost of the relays."

Technological advancements

Various advancements are taking place at the component and material
level in relays. For instance, the contact resistance of relays is being
reduced by adopting new materials and coatings for the contacts. This is
done by R&D into complex metallic alloys and surface coats, which plays
a significant role in the low-power relays where room for contact losses
is not present.

"Another area of development is the consumption reduction of coil
power. This is done by improving the magnetic characteristics and
polarization of fluxes. It helps in the reduction of coil power
consumption and undue heating. Also, continuous research is happening to
develop complex alloys, which has the capacity to withstand repeated
arcing with minimum deterioration,"
adds Amey.

Increasing product portfolio and adoption of EVs

The development and adoption of alternative fuel vehicles are considered
as major solutions to reduce the emissions of greenhouse gases.
Alternative fuel vehicles run on alternative sources of energy, such as
electricity, hybrid energy, solar energy, wind energy, or biofuels.
APAC, North America, and Europe implement stringent regulations on fuel
emissions and consumption, and tax incentives for the increased adoption
of EVs.

The upcoming expansion of the product portfolio for hybrid EVs by top
OEMs is another reason for the increased vehicle sales in the market.
Currently, the global market has about 50 best-selling hybrid models and
20 pure EV models. OEMs are also planning to launch the next generation
of vehicle models. Nissan Rogue and Kia Niro are the new product
