ecovolta’s next generation of traction batteries offers 172 Wh/kg specific energy
ecovolta has launched a new generation of its evoTractionBattery traction battery, which it says offers specific energy of up to 172 Wh/kg. The battery packs, which are certified to automotive standards, are designed for commercial EVs, construction machines and boats. The new generation is available in 48- and 96-volt versions, and offers four different memory… Read more »
The ideal fluid control valve for EV thermal management
Sponsored by TLX Technologies The increasing demand for EVs are driving design teams to search out innovative fluid management solutions for EV thermal management applications. Unlike internal combustion engines, which have relatively simple cooling systems, EV cooling systems must be able to manage multiple heat sources and sinks, each with specific optimal operating temperatures and… Read more »
Stanford study: 100% renewable US grid is feasible and reliable
How many times this week have you read that renewable energy is unreliable, and will never be able to completely replace fossil fuels on the electrical grid? Well, there is at least one group of scientists who don’t agree. A study led by Stanford University Professor Mark Jacobson has found that a US energy system… Read more »
Sandia National Laboratories study voltage loss across battery interfaces
Scientists at Sandia National Laboratories may have discovered a way to make a longer-lasting, more efficient battery. The team used Kelvin probe force microscopy to locate places where electron flows get stuck. Solid-state batteries use solid electrolytes instead of electrochemical gels and liquids. Researchers suspected that there was a loss of voltage at interfaces within… Read more »
2022 Hyundai Ioniq 5: Strong new electric SUV competitor
Hyundai’s new compact EV crossover is good enough to sell every unit the company imports—the question may be how high that number will be. The 2022 Hyundai Ioniq 5 is the Korean brand’s first dedicated electric vehicle, positioned at the heart of the fastest-growing part of the market: compact crossover utilities. The premium electric SUV… Read more »
Parker LORD adds thermally-conductive adhesives to its EV portfolio
Parker LORD has expanded its EV product portfolio to include thermally conductive (TC) adhesives and one-component low-density gap fillers. The new adhesives are part of a strategy to create lighter-weight and smaller-footprint products that can help deliver additional energy density. Methods under development include bonding individual cells directly to the cooling plate and bonding directly… Read more »
KACO further develops its quick-venting battery deflation system
KACO has further developed its quick-venting modular system for battery deflation. The products include reversible and irreversible solutions with a configurable breathing membrane. If an unintentional fault occurs in the traction battery of an EV or hybrid, rapid emergency venting is needed to reduce the pressure in the affected battery segment. Depending on customer specifications,… Read more »
A closer look at minimizing AC charging losses: From the breaker to EV (Part 1)
It’s fairly well known by now that EVs cost far less per mile to drive than their closest ICE counterparts, and the main reason is simply that the EV drivetrain is far more efficient at converting its stored form of energy into motion. In the quest to improve efficiency even more, the focus tends to… Read more »
Flexible, scalable battery test for high power battery systems
Sponsored by Elektro-Automatik EA-PSB 10000 bidirectional, regenerative and auto-ranging programmable DC power Growing demands placed on modern batteries and accumulator systems present manufacturers with major challenges. On one hand, their systems have to provide more performance, service life and safety; on the other hand, end consumers expect products that have an attractive purchase price and… Read more »
