Welcome to the July issue!
This month, we celebrate the semiquincentennial of a very special little experiment that most of us call home. She may not be perfect (who is?), but she’s afforded me and countless others a wealth of opportunities over 2 ½ centuries, and I consider myself extraordinarily fortunate

Welcome to the July edition of Power Systems Design Europe. Having just returned from the PCIM exhibition in Nuremberg, it’s hard not to feel positive about the industry. I talked to well over 20 companies at the show, and almost everyone was introducing new products that gave power solutions higher performance, be

The pressure on industrial and medical equipment manufacturers has never been more intense. Customers demand higher uptime, leaner operating costs, and power systems that adapt to the job rather than dictating its terms. Traditional fixed-battery architectures — solid and predictable as they may be — are in

Figure 1: Simplified three-phase flying-capacitor inverter topology
The global transition toward a decentralized renewable energy infrastructure has fundamentally changed the voltage and density requirements of utility-scale Energy Storage Systems (ESS). To reduce conduction losses, minimize cable cross-sections, and optimize structural balance-of-system (BOS) costs, modern ES

Figure 1: Simplified BMS topology showing charge and discharge MOSFETs
While higher-voltage battery platforms improve efficiency and reduce current, they also introduce a more demanding challenge: safely managing fault energy during abnormal conditions.
External short circuits in high-voltage systems can generate extreme currents within microseconds, placing the battery managemen

Figure 1: Simplified block diagram for the L99BM114 BMS
Humanoid robots are redefining power-density constraints. To preserve agility and reduce structural inertia, designers typically place the battery pack deep within the torso or pelvis. This compact architecture means the energy-storage system must operate inside a sealed enclosure, often alongside high-perfo

Figure 1: Impact of capacity-mismatched cells during battery pack charging and discharging
In a BMS, multiple individual cells are typically connected in series to form a high-voltage battery pack. This high-voltage battery pack is the supply for various systems, including electric vehicles, high-voltage energy storage systems, and uninterruptible power supplies. In these series-connected cells, th

The global batteries and energy storage device market is expanding rapidly, driven by electrification, renewable energy adoption and the proliferation of portable and connected technologies. There are roughly 360 global battery-related events each year—a volume reflecting the scale of industry attention an

Singaporean-based commodities company Trafigura just signed a massive $1.1 billion, 10-year offtake agreement with US-based refiner Nth Cycle. The goal – to recover 2,000 metric tons of nickel in mixed hydroxide precipitate and 1,500 metric tons of lithium carbonate from mostly lithium-ion batteries and so

Anyone who has a Facebook account has likely come across at least one post that describes how electric vehicles are unsustainable, usually followed by a bullet list of points that are supposed to prove the argument. It has previously been difficult to find actual data to either support or counter this claim. Mo
