6 FAQs about [Big battery and high power charging]
Is high-power charging a good idea?
Not necessarily. High-power charging is great for long-dis-tance travelers and “street lamp” parkers who might not have access to overnight AC charging at their homes. Higher currents can stress vehicle components, including the battery’s chemistry.
What does high-power charging mean for EV fleets?
For Meintz, high-power charging for EV fleets represents a paradigm shift—away from the diesel systems that have powered heavy vehicles for more than a century, and toward a system that can handle different streams of energy produced from renewable energy sources like the sun, the wind, and the waves.
Why should a car battery have a high current?
Higher currents can stress vehicle components, including the battery’s chemistry. There will always be a need for both slower AC and DC charging and fast, high-powered, and megawatt DC charging to address drivers’ needs for com-fortable long-distance travel and to keep their electrical systems eficient, well-maintained and afordable.
What is a Smart EV charger?
They are also "smart": In other words, they can optimize an EV's energy consumption and reduce the cost of charging. Smart chargers can help fleets, governments, private businesses, and charging stations to offer cost-effective charging that never overloads the electrical grid.
What is DC high-power charging (HPC)?
Currently, the industry is developing DC high-power charging (HPC) to provide the same amount of charge (200 miles of range) in 10 minutes or less, producing an experience similar to filling up one’s gas tank in an internal combustion engine (ICE) vehicle.
Can high-power EV charging connectors overheat?
Through evaluation events hosted in NREL's world-class facilities, researchers ensure that high-power EV charging connectors from major manufacturers can provide up to 3.75 MW of electricity, can plug into commercially available EVs, and will not overheat or shock the user, even when misused.
