EV charging jobs involve designing, building, testing, and manufacturing charging stations, batteries, and related equipment and systems for electric cars. As an EV engineer, you perform research and develop lithium-ion batteries for use in these electric vehicles. Your duties also include designing and testing stations where owners can recharge their battery-powered cars, whether out in public or on their own property. A test engineer then ensures that these products work in real-world environments and meet safety standards. Technicians and manufacturing workers assemble the batteries and stations once the engineers have completed and tested the designs.
