DIN-rail power supply buffer module has inhibit function for safe operation
TDK Corporation announces the introduction of the TDK-Lambda brand DBM20 24V 20A rated DIN rail buffer module. The narrow 49mm width saves space on the DIN rail allowing additional modules and functionality to be fitted. A remote on/off inhibit function avoids the unsafe discharge of stored energy during system maintenance and servicing. The DBM20 provides […]
Battery breakthrough fatigue
Leland Teschler • Executive Editor For some cheap thrills, try Googling the words “battery breakthrough.” You’ll be presented with page after page of articles breathlessly chronicling one research result after another in energy storage. But you might wonder why, with so many earth-shattering developments, electric vehicles can’t travel 1,000 miles before needing a recharge. The […]
Isolated high-power current-sense modules include amplified analog output
New Yorker Electronics has announced the release of the new SSA Smart Current Sensor series from Riedon. Riedon’s new Smart Shunt SSA combines low-impedance manganese shunt resistance, a high-precision insulated amplifier, and an isolated DC/DC converter. Riedon’s SSA family of Isolated Smart Current Measurement Technology consists of four current ratings: 100A, 250A, 500A, and 1000A. […]
Bi-directional 22/25-kW liquid-cooled inverter battery charger targets EV, HEV apps
Bel Power Solutions announces the BCL25-700-8, a 22/25 kW bi-directional liquid-cooled on-board inverter battery charger with export functionalities for hybrid (HEV) or fully electric (EV) vehicles, as well as medium and heavy-duty on- and off-highway vehicles. The BCL25-700-8 is parallelable up to 4 units in charge mode, with typical efficiency up to 94%. With the […]
Power-management ICs optimized for use in laptops
MagnaChip Semiconductor Corporation announced a new line of power management integrated circuits (PMIC) by introducing its first UHD display panel PMIC for laptops. PMICs are integrated circuits that include multiple power management functions within a single chip, and they are frequently used to power space-constrained devices where high-efficient and compact form factors are required. They […]
Understanding stop/start automobile-engine design, Part 3: The battery situation
The stop/start approach has significant implications for the car’s battery and battery management system (BMS). Q: How does the battery charge/discharge cycle function in a non-stop/start vehicle? A: In a car without a stop/start system, starting the engine is a one-time event for the duration of the trip. While the engine is running, it also […]
Now that’s cold: Batteries for covid vaccine handle -112°F
Bobbin-type lithium thionyl chloride (LiSOCl2) batteries from Tadiran Batteries are being specially modified for use in the cold chain demanded by Covid vaccine made by Pfizer. Pfizer says it has specially designed temperature-controlled thermal shippers utilizing dry ice to maintain recommended storage temperature conditions of -70±10°C for up to 10 days unopened. The firm will […]
