Introduction:
Volvo is on a mission to speed up the process of charging electric vehicles (EVs) using software solutions rather than making physical upgrades to batteries and other hardware. The automaker has partnered with Breathe Battery Technologies, a company based in the U.K., to access their algorithm-enabled charging software with the aim of optimizing charging performance. This innovative approach could significantly reduce the time required to charge an EV battery pack from 10% to 80%, while maintaining pack energy density and range.
1. The Partnership with Breathe Battery Technologies
Volvo’s collaboration with Breathe Battery Technologies is focused on integrating the company’s algorithm-enabled charging software with Volvo’s battery management systems. This software is designed to manage charging more efficiently than the current stepped charging protocols, which rely on preset rules. By analyzing battery health in real-time, Breathe’s algorithms allow for more flexibility and potentially quicker charging, as claimed by Volvo. The partnership is being supported by funding from the Volvo Cars Tech Fund, showcasing a commitment to innovation in the EV charging space.
2. Research-based Charging Innovations
Apart from Volvo’s partnership with Breathe Battery Technologies, other researchers and automakers are exploring research-based solutions to enhance charging efficiency. University of California Riverside researchers have proposed closely monitoring the internal resistance of battery cells to prolong pack lifespan. This approach minimizes the need for expensive upgrades to battery packs and cooling systems, offering a more cost-effective and sustainable solution in the long run.
3. Advancements in Solid-State Battery Technology
Toyota, Nissan, and various cell manufacturers are actively working on solid-state battery technology, which has the potential to revolutionize the EV charging landscape. Solid-state batteries may enable super-fast charging speeds, allowing for rapid replenishment of EV batteries. Polestar, Volvo’s sibling brand, is conducting tests on solid-state tech that could restore 100 miles of range in just five minutes. Additionally, Lotus is among the few companies achieving DC fast charging speeds above 400 kW with current liquid electrolyte battery formats, highlighting the continuous advancements in battery technology.
4. Future Plans and Innovations by Volvo
In addition to accelerating EV charging times, Volvo is venturing into the energy business and preparing for the launch of the EX90, its first EV equipped with bidirectional charging capabilities. Bidirectional charging allows EVs to not only draw power from the grid but also return excess energy back, creating a more sustainable and efficient energy ecosystem. By investing in software-driven solutions and embracing cutting-edge technologies, Volvo is paving the way for a future where EVs are seamlessly integrated into our daily lives.
5. The Road Ahead for EV Charging Technology
As Volvo and other automakers continue to push the boundaries of EV charging technology, the industry is set to witness profound changes in the coming years. From software-driven solutions to advancements in battery technology, the focus is shifting towards making EVs more accessible, convenient, and environmentally friendly. With solid-state batteries, bidirectional charging, and high-speed charging capabilities on the horizon, the future of EVs looks promising, promising a future where electric mobility is the norm rather than the exception.
