Sponsored by Elkem Silicones Heat dissipation is critical for the electronics and batteries to function for their intended lifetime and reach the desired levels of performance and reliability in EV applications. Without proper thermal management, lithium-ion batteries can overheat during charging or discharging. There can also be a non-uniform temperature distribution within the battery packs which… Read more »
Sponsored by EPCOS, a TDK Group Company By Matt Reynolds, Director of Marketing, Piezo and Protection Devices The technology behind capacitors has been around since late 1745 when a physicist in Germany found that an electrical charge could be stored by connecting a high-voltage electrostatic generator by a wire to a volume of water in a hand-held… Read more »
Sponsored by Chroma Systems Solutions An automotive DC-DC converter receives high voltage from the battery and converts it to a lower voltage to power on board devices such as the instrumentation panel, entertainment system, sensors, LED lighting, and any other on board devices requiring low voltage DC power. Manufacture’s strategies in DC-DC converter development include reduction in size… Read more »
Heat generated in high-density automotive battery packs is often managed by connecting battery cells and/or modules to a heat sink via a thermal interface material (TIM). The TIMs promote heat conduction by displacing any air that resides within the large gaps and microscopic rough surfaces that exist between the substrates to be bridged. In practice, battery… Read more »
Sponsored by Littelfuse By Carlos Castro, Global Director Marketing Automotive Electronics, Littelfuse, Inc. As hybrid and electric vehicles roll closer to battery power drive systems with 48V or higher, the lithium-ion battery in a closed system is the clear leader for power. Lithium-ion gets high marks in cost, energy efficiency, temperature performance, power-to-weight ratio and lifecycle…. Read more »

Sponsored by AVL Local air pollution, noise emissions, global CO2 reduction and public pressure are driving the need for zero emission transportation solutions in urban areas. Many OEMs are currently developing electrified heavy duty vehicles that maximize range and durability, while minimizing the total cost of ownership, system weight and vehicle packaging – electric axles… Read more »
Sponsored by Keysight Technologies Traditional methods for measuring Lithium-Ion self-discharge of cells tracks a cell’s open-circuit voltage over time, taking days or even weeks, with added costs from large holding areas needed. A new potentiostatic test method enables cell designers and manufacturers to evaluate cell and battery performance in a fraction of the time. Learn… Read more »
Sponsored by HBM The eDrive solution from HBM acts as both a power analyzer and data acquisition system. It has the ability to record ALL signals along the drive train (power source, inverter, torque and speed of a motor, temperatures, CAN signals, strain, vibration, etc.) with a single instrument. This greatly reduces the test complexity and results… Read more »
