The Power of Signalling

Autovista Group, TÜV Rheinland and TWAICE have teamed up to explore the potential impact of Battery Health Reports (BHR) on remarketing success of the battery electric vehicle (BEV) in a new whitepaper. Besides age and mileage, driver profile has a major impact on how long a battery lasts. In the absence of documentation of how a driver has treated the battery, residual value formation remains below its full potential.

Economizing with battery analytics

A lot has happened in the world of electric buses over the past year. Many new projects have been announced or started. The early adopters – those that started introducing electric buses into their fleets four or five years ago – can offer helpful insights to the future for many. Over the past couple of months, ViriCiti and TWAICE have worked closely with such an early adopter on how to integrate data-driven decision making – focusing on batteries – to avoid timely and costly warranty discussions.

Mercedes-Benz is just the latest in a long line of companies committing to an all-electric product line-up. Central to this transition in the mobility space is the lithium-ion battery. Outside the automotive industry, these batteries are already a key technology. But while the battery is a powerful enabler, it can also be an Achilles’ heel. We talked to TWAICE battery modeling engineer Goku, who explains the most pressing issues.

Impedance Research Paper

Impedance is an important characteristic of lithium-ion batteries since it directly influences their power capability. However, battery impedance is highly dependent on the operating condition and increases over the lifetime of the battery, due to degradation of the latter. Continuous tracking of the impedance can hence provide meaningful insights into the aging status of a battery.
