Battery testing: critical to the rise of electric vehicles
When designing a battery into an EV, you must perform rigorous testing to understand a battery’s performance. Electric vehicles (EVs) accounted for 13% of global vehicle sales in 2022 and are forecasted to reach 30% of global vehicle sales by 2030. The industry needs to continue working on making EVs affordable to support this transition…
4 kW liquid-cooled dc-dc converter creates DC voltages in hybrid and EVs
Bel Fuse Inc. announced the release of the Bel Power Solutions 700DNG40-24-8, the second generation 4 kW liquid-cooled DC-DC converter. The unit creates DC voltages in hybrid and electric vehicles suitable to power low-voltage accessories, replacing a traditional alternator. The new converter is smaller and operates at a wider input voltage range from 450 to […]
Current sensors and current shunt monitors for common-mode voltages and temperatures
Texas Instruments debuted new current sensors to help engineers simplify their designs while improving accuracy. Designed for a broad range of common-mode voltages and temperatures, the new products include a lowest-drift isolated Hall-effect current sensor for high-voltage systems and a portfolio of current shunt monitors that eliminate the need for an external shunt resistor for […]
MOSFETs for high-voltage ECUs feature EC7 co-packed diode with emitter-controlled design
Infineon Technologies AG expands its 7th generation TRENCHSTOP IGBT family with the discrete 650 V IGBT7 H7 variant. The devices feature a cutting-edge EC7 co-packed diode with an advanced emitter-controlled design, coupled with high-speed technology to address the escalating need for environmentally conscious and highly efficient power solutions. Using the latest micro-pattern trench technology, the […]
How many electric motors are in a car?
The first gasoline cars had no electric motors; in contrast, today’s cars have tens of “invisible” motors having a range of power levels, sizes, and types. It’s not news that today’s cars, regardless of their motive power source, are packed with what is called “electronics.” Whether it’s for power trains, Advanced Driver Assistance Systems (ADAS), […]
EV battery tests involve lots of power
In a video, EE World spoke with a power-supply applications engineer about why RV batteries use such high voltages and how to test them. Batteries are perhaps the most expensive component of an electric vehicle. Typically producing 800 V to 900 V, batteries deliver the power needed move the vehicle. Of course, EV batteries need…
TVS components provide circuit protection for EVs and HEVs
Inelco Hunter has announced the availability of two new ProTek Devices TVS Components. They are designed for circuit protection across a variety of electric and hybrid vehicle systems including charging systems and automotive electronic control units (ECUs). The 7,000 Watt PAM7KSMDJ24CAP is suited for circuit protection across the belt starter (BSG) generator circuit, the integrated […]
How is functional safety defined & implemented for batteries in EVs and BESS?
Li-ion batteries can store large amounts of energy, and they can support high rates of power delivery. They are the preferred energy storage technology for EVs and large battery energy storage systems (BESS). But if not properly managed, they can also present safety hazards. That makes functional safety a critical consideration when designing large Li-ion…
How does MBSE work for EV and stationary battery energy storage systems?
Model-based systems engineering (MBSE) is comprehensive. The International Council on Systems Engineering (INCOSE) defines MBSE as the “formalized application of modeling to support system requirements, design, analysis, verification, and validation activities beginning in the conceptual design phase and continuing throughout development and later life cycle phases.” It’s especially applicable to complex systems of systems like…
