Wide-scale adoption of electric vehicles (EVs) is happening through a combination of incentives and laws. For example, the US Government aims to ensure that EVs are half of all the new vehicles sold by 2030. The UK plans to ban fossil fuel cars from … [Read more...]
How to select a dc-link capacitor for EV fast chargers
Electric vehicle (EV) fast charging stations are gaining considerable attention and growth in the market, which means an increasing demand for specialized passive components. Given the high-power, high-energy levels involved — particularly at the … [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...]
What is bidirectional power transfer?
Bidirectional power transfer (BPT) is a critical technology enabling efficient and cost-effective electric vehicles (EVs). Simply put, BPT allows electrical energy to flow in both directions through a power converter. Energy recycling is the primary … [Read more...]
What is the difference between ac and dc EV charging?
EV charging is highly standardized, and the standards are primarily focused on safety and connectivity. The standards between regions. One common thread is the availability of separate standards for ac and dc charging. This FAQ reviews the basic … [Read more...]
Bidirectional power for EVs: Practical and creative opportunities using power modules
Given the coexistence of 400 V and 800 V EVs on the road, what options are there to harmonize these two distinct architectures? We all know the race is on for electrification, whether through government mandates and incentives or consumers … [Read more...]
What is WEVCS wireless charging?
Electric vehicles (EVs) are shaping the future of mobility, as nearly all EVs are more economical than those that run on gasoline. In fact, more electric vehicles are expected to be on the road than fossil fuel cars by 2030. Most EVs range from … [Read more...]
What are the different types of EV charging connectors?
There are several reasons to consider an electric vehicle (EV) aside from saving on gasoline. The prominent one, of course, is the environment. EVs have no tailpipe emissions, and research shows they’re responsible for lower levels of greenhouse … [Read more...]
How fast can Li-on batteries be charged?
The speed at which a battery can be recharged is measured using the ‘C-rate,’ where ‘C’ is the battery’s capacity in mA or A. At a 1 C rate, a battery can be completely recharged in one hour. The speed of charge primarily depends on the … [Read more...]
