Designers can now achieve ASIL-D compliance for automotive applications using just a single chip for a safer, more cost-effective battery management system with the MAX17853 battery monitor IC from Maxim Integrated Products, Inc. Targeting mid-to-large cell count configurations for automotive applications, such as battery packs for electric and hybrid vehicles, MAX17853’s unique flexible architecture called […]
Gridtential, Crown Battery partner on silicon+lead battery
Using technology similar to a solar cell, Gridtential Energy’s breakthrough Silicon Joule technology allows batteries to deliver up to five-times the power density with up to a 40% weight reduction — and it can be manufactured in current lead battery plants. Silicon Joule technology replaces the lead-grid and cell connecting lead-strap material inside a traditional…
Charging electric vehicles, Part 1: The numbers
It’s nice to envision that recharging an electric vehicle is as straightforward as filling up an internal combustion vehicle, but it’s not: there are multiple charging, power, and connector options as well as limitations. You’re driving your internal-combustion (IC) car, and the gauge indicates it’s time to get “gas” (of course, it’s actually gasoline). So […]
Onboard battery charger revs up HEV and EVs
Bel Power Solutions today announced the BCN25-700-8, a 25 kW onboard battery charger that converts 3-phase AC voltage to DC voltage. The enclosure is made of aluminum alloy and is liquid-cooled. Providing 25 kW of output power for a single unit, and up to 100 kW of output power for 4 units, the BCN25 has […]
EV charger reference design employs GaN for 3 kW/L power density
VisIC Technologies, Ltd announced the availability of its On-Board-Charger (OBC) reference design for the fast-growing Electrical Vehicle (EV) market. The 6.7kW OBC features a size and weight of only 2.3L and 4.5kg respectively, providing close to 3kW/L power density and proving the disruptive capability of GaN switches. This is 3 x better power density compared […]
Galvanic isolation for electric vehicle systems
High voltages and high currents circulating in EVs make the fundamentals of electrical isolation techniques an important topic. Ross Sabolcik, Silicon Labs AS automotive designs move toward electrification, high-wattage power electronics become critical to new electronic drivetrain and battery systems. In these applications, digital controllers safely interface with the high-voltage systems of modern electric vehicles […]
