Automotive Connectivity

Training Center Classroom

Welcome to this installment of EE Classroom on Automotive Connectivity.

Despite the relative scarcity of charging stations and limited supply of vehicles, EV sales adoption in the U.S. alone is expected to grow from an estimated 21% to 53% by 2030, according to Boston Consulting Group. Even with half the expected growth that growth, the pressure is on to address the significant design problems that electrification brings to automotive design—stress, vibration, high-temperature, and high-reliability requirements of connectors both on- and off-board, not the least of them.

Use this classroom to come up to speed on the latest EV connector standards, safety, and the electrical and physical connections involved in charging electric vehicles. Learn how multi-gigabit Ethernet and 5G are addressing automotive high-bandwidth requirements. Finally, take a refresher course in EMI, as well as what to watch out for board-to-board and wire-to-board designs, particularly with connector miniaturization.

EVs • Charging

What's the status of EV connector standards?

Protecting fast EV charging stations

Charging electric vehicles: connections

Connectors for electric vehicle (EV) charging are both standardized and changing.

Design engineers face multiple challenges in developing EV charging stations. Most important is that of safety.

Issues related to charging of electric vehicles with a look at the hardware.

Networking • High-Speed

What is the ideal Ethernet choice of automotive applications?

CAN for better autonomous vehicles

What high-speed data means for connected vehicles

Conventional Ethernet is too sensitive to interference and too noisy for most automotive applications.

Technologies behind multigigabit Ethernet and 5G could transform transportation.

As autonomous vehicles mature, so will their needs for higher-bandwidth data transmission capabilities.

EMI • Wire-to-Board

The connector is often the EMI problem

Where are wire-to-board connectors used

Why do connectors fail?

A a look at some common causes of failure and how to prevent them.

It only takes 3 µA of current to fail an EMC test, and a connector can produce that much.

These connectors serve as an efficient and cost-effective method for delivering power and signals to PCBs in automotive.
