Polestar granted on Tuesday the U.S. Patent no. 11,364,814, a dual battery system for electric vehicles. The patent was signed by Jongseok Moon, the Battery engineer working with the Swedish EV maker since November 2018 and says, ” (…) with the dual batteries rather than a single battery, an increased battery lifespan for an electric vehicle is supported”.
The patent says that this dual battery system may support “different driving situations, where either the first or the second battery or both may be utilized” but also that that supports “an increased battery lifespan for an electric vehicle”.

“The dual battery system receives an input signal indicating selection of the first battery and/or the second battery, the first battery being configured to provide electric power for driving the first electric motor and the second battery being configured to provide electric power for driving the second electric motor,” can be read in the summary.
Polestar engineer adds that “the first battery configuration may be tailored to satisfy a first driving scenario and the second battery configuration tailored to satisfy a second driving scenario”. In addition, he explains that the battery configuration “may be balanced to be beneficial to use for powering propulsion of an EV for a first driving pattern and/or distance”, different from the second one.
The differences in the configuration are made by “balancing one or more design ratings e.g. in terms of life cycle rating, energy density, specific power, charging time, resistance, and thermal stability”. The different approaches will satisfy the different needs of several driving scenarios such as typical short distance driving, urban driving and/or commute driving versus long distance driving and/or extended driving.

Patent’s abstract says, “The present disclosure relates to a dual battery system for in a dual manner powering propulsion of an electric vehicle including a first electric motor coupled in driving relationship to one or more rear wheels and a second electric motor coupled in driving relationship to one or more front wheels”.
On Tuesday, Polestar released the P2.2 version of its software introducing the eagerly awaited Apple CarPlay system among other new features. The arrival of the system to the models of the Swedish manufacturer had been confirmed in late May by its CEO, Thomas Ingenlath.
Alongside the integration of the system, the new version also brings improvements to wireless charging for Apple products, preparation for future video streaming apps, and a better read of the road sign information.
Also on Tuesday, Polestar and Gores Guggenheim announced that they expect to close their business combination on June 23, subject to Gores Guggenheim stockholder approval. Following the consummation of the business combination, the Swedish EV maker is expected to begin trading on Nasdaq on Friday (June 24) under the new ticker symbol “PSNY.”
Last week, the company announced that had over 32,000 orders globally for Polestar 2 since the start of 2022, representing a increase of 290% versus the same period in 2021. As the global expansion continues, the swedish electric vehicle maker is now 5 markets away from the plan of being present in 30 countries by end of 2023.
