Why Are Connectors For Electric Vehicles Important?

Jun. 28, 2022

As electric vehicle (EV) sales continue to grow significantly (due to policy support, improvements in battery technology, lower battery costs, more charging infrastructure, and new model launches by automakers), managing future supply chains and production systems to maintain growth trajectories is critical to any EV strategy. With the global semiconductor shortage affecting the design and production lifecycle of the automotive industry, designers need the support of suppliers and distributors more than ever, especially when it comes to EV connectors.


Why are connectors for electric vehicles important?

While the electric vehicle market is growing, it faces very real competition. While petroleum-based automotive solutions have many drawbacks, their convenience is undeniable. Fuel can be pumped into any vehicle with virtually no difficulty, as opposed to charging an electric vehicle. Each electric vehicle may have its own uniquely designed industrial connector, making connectors a serious issue for electric vehicles.


Electric Vehicle Connector Challenges

The compatibility of most electrical equipment is not a challenge because the use of standardized connectors and nationally standardized supply voltages makes everything easy. While a reliable power grid solves the frequency and voltage issues facing EVs, connector specifications are still difficult.


Electric vehicle manufacturers further complicate the connector issue by utilizing multiple EV charging modes, including

New Energy EV Connectors

New Energy EV Connectors    

Mode 1 for slow charging from a typical household outlet

Mode 2, which allows faster charging from a specially designed home outlet

Mode 3 for commercial street-side charging points

Mode 4 for fast DC charging


In addition, EV connectors must incorporate several key design features: they should be 


Ergonomic and easy to use

Save space

Include built-in safety features

Be able to provide AC and DC power


CCS connectors: solution or not?

The CCS (Combined Charging System) connector combines all of these design features, so designers may think that all of the problems associated with EV connectors have been solved. However, this is not necessarily the case.


CCS connectors meet the customer requirements for EV connectors, but from an electrical engineering perspective, there is still a lot of work to be done. For example, the high voltages and currents that occur when charging EVs create the perfect environment for arcing between contacts. While the use of a pilot signal can greatly mitigate this situation, as any loss of continuity immediately stops charging, it still does not completely prevent resistor overheating or contact damage. 


However, a little effort in contact design can mitigate this situation.
