The battery is in its second century. And with more car buyers now opting for electric, it seems a good opportunity to recognize what batteries have done for humankind, and the advantages their technology offers the mobility and energy spaces.

The importance of e-mobility to sustainability and environmental awareness continues to grow. Some of the trends that will be emerging for this year include battery-drive at the cutting edge, image change for batteries, and second life batteries enabled by software analytics.

Even though batteries are a controversial topic, most manufacturers and legislators rely on battery electric vehicles because of its advantages over other alternatives. This article examines why batteries are the future of mobility and play a key role for renewable energies.

Numerous recent recalls showed how much risk is associated with the most important competent of the emission-free mobility. The battery is a highly complex piece of technology that must be tightly analyzed not only during the development but also during operation.

The electrification of mobility is accelerating quickly and turning the automotive industry and other major industries upside down. With electrification the focus shifts away from the engine towards the batteries.

Electric vehicle batteries are costly and sensitive parts, and their performance depends on numerous factors like frequency of charge and discharge, the charging system, driving habits, and external temperature. Until now, it was almost impossible for developers or users of batteries to make any reliable analysis or statement about the current state of the device. However, this information can be now delivered by the digital twin created by TWAICE.

Batteries are highly complex electrochemical systems with different cell formats and chemistries being used. The processes inside the battery also deserve particular attention.

Energy storage is booming, and with growth comes complexity. That’s why TWAICE and Camelot Energy Group, an independent consultancy, teamed up to kick off a new webinar series focused on the BESS lifecycle starting with one of the most crucial phases: planning. This first session packed in practical guidance and real-world lessons for developers looking to future-proof their BESS projects. Here’s a summary of the main takeaways.
