NXP Semiconductors has announced the MC33777, a battery junction box integrated circuit (IC) that combines sense, think, and act capabilities for battery management systems. The MC33777 integrates pack-level functions into a single device, which differs from conventional solutions that use multiple discrete components, external actuators, and processing support. The MC33777 IC monitors battery current and…

Lithium-ion (Li-ion) battery traction packs power most electric vehicles (EVs) on the road today. These batteries enable electric motors to efficiently generate the high torque required for rapid acceleration and consistent speeds. Although Li-ion batteries offer high energy density and a relatively long lifespan, many automotive companies are actively researching and developing solid-state battery technology.…

Battery technology is the foundational element of electric vehicles (EVs), influencing their efficiency, range, charging speed, lifespan, cost, and overall performance. Engineering firm Bosch Rexroth is well aware of how battery manufacturing affects every one of these factors. It believes innovations in battery technology and advanced manufacturing processes are essential for the widespread adoption and…

Researchers at Chung-Ang University used high-concentration electrolytes to improve safety and prevent cell swelling caused by lithium plating. To achieve a greater adaption of electric vehicles, the automotive industry needs fast-charging batteries that don’t compromise energy density. Lithium plating for ultra-fast charging raises safety concerns due to high cell polarization, requiring careful attention. During fast…

Battery testing enables vehicle manufacturers, owners, and researchers to make informed decisions, optimize vehicle performance, and enhance overall user experience. Demand for electric vehicles is amping up. Every one of these vehicles needs large batteries, and the industry is responding by building plants. Energy.gov forecasts that by 2030 electric vehicle battery manufacturing capacity in North…

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…

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…

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…
