Q&A: What the shift to chrome-free coatings means for EV design
The transition away from traditional chrome-based coatings presents new challenges for electric vehicle (EV) manufacturers. Alternative surface treatments must provide the same level of protection against corrosion and wear while meeting the electrical and mechanical demands of EV components. Coating selection can affect component performance and long-term reliability. Introducing new chemistries also requires careful validation…
New battery architecture could extend EV battery life by over 20%
Researchers at Chalmers University of Technology in Sweden, working with industry partners, have investigated a reconfigurable battery architecture that could extend electric vehicle (EV) battery life by more than 20% under certain conditions. The approach allows deteriorating cells to be bypassed rather than limiting the performance and lifespan of an entire battery pack. Battery packs…
New battery monitoring IC integrates EIS diagnostics for EVs
Nuvoton Technology Corporation Japan has introduced the KA85010UA, a sixth-generation battery monitoring IC that integrates electrochemical impedance spectroscopy (EIS) for electric vehicle (EV) battery diagnostics. The IC monitors up to 26 battery cells and uses EIS to assess internal battery conditions that are difficult to identify through conventional voltage and temperature measurements alone. The technology…
Three new thermal adhesives introduced for EV battery applications
Parker Hannifin‘s Performance Materials Division has introduced three new thermally conductive adhesives to its CoolTherm portfolio for electric vehicle (EV) battery manufacturing and other electrification applications. The new formulations address different bonding and thermal management requirements, with variations in cure time, substrate compatibility, and dispensing characteristics. CoolTherm UR-2800 is a thermally conductive urethane adhesive designed…
