Why EV engineers are turning to liquid-cooled charging systems
Electric-vehicle (EV) connectors and charging cables must safely handle increasingly high currents and power levels. Conventional air-cooled cables and connectors begin to reach practical limits around 250 A continuous, with some designs capable of … [Read more...]
Part II: How engineers are optimizing dc fast-charging systems for interoperability and V2G
In Part I of this interview, Mike Calise, CEO of Tellus Power, discussed how engineers ensure grid stability, system safety, and reliability in high-power dc charging networks. In this second installment, the conversation turns to the … [Read more...]
How fast and ultra-fast charging are changing the EV experience
A decade ago, adding 100 miles of range in under half an hour was more aspiration than reality for most electric vehicles (EVs) in the United States. Today, fast and ultra-fast charging have become critical enablers of EV adoption, typically … [Read more...]
How high-power dc fast chargers manage heat and impact EV batteries
Fast electric vehicle (EV) charging standards, such as the Combined Charging System (CCS) and Charge de Move (CHAdeMO), regulate the safe, efficient delivery of direct current (dc) to battery traction packs. As shown in Figure 1, high-power dc … [Read more...]
How can liquid cooling be applied to charging cables during dc fast charging?
Integrating a liquid coolant system into the cable assembly and connector housing of electric vehicle (EV) charging infrastructure moves coolant around the high-current wires and connectors. The liquid coolant circulates through jackets or channels … [Read more...]
What are the challenges with high-voltage EV charging?
With existing battery technologies, higher voltages are the key to faster charging and reduced range anxiety. Current fast charging stations can deliver up to 600 Vdc and 400 A for a total power of 240 kW and charge an EV battery pack up to 80% in … [Read more...]
