Volvo is trying to quicken EV charging instances by counting on software program quite than upgrades to batteries and different {hardware}.
The automaker on Monday introduced a partnership with U.Ok.-based Breathe Battery Technologies to entry that firm’s “algorithm-enabled charging software” with its battery administration techniques—with the aim of optimizing charging efficiency.
Testing has indicated that this software program might scale back the time to cost an EV battery pack from 10% to 80% by 15% to 30%, relying on the pack, whereas sustaining pack vitality density and vary, Volvo mentioned in a press launch.

Software developed by Breathe, which is receiving funding from the Volvo Cars Tech Fund, can extra carefully handle charging in comparison with present stepped charging protocols, based on Volvo. While stepped charging depends on preset guidelines, Breathe’s algorithms can handle charging primarily based on real-time evaluation of battery well being, permitting for extra flexibility and doubtlessly faster charging, Volvo claims.
This is not the one type of charging innovation that is extra research-and-algorithm primarily based than hardware-based. University of California Riverside researchers a number of years in the past prompt that by carefully following the interior resistance of battery cells, they might make packs final far longer.
Upgrading battery packs and switching battery cells prices cash, and upgrading battery cooling prices effectivity. That’s left automakers pondering some modern workarounds, at the least in patent type. Rivian, as an illustration, thought-about blowing cool air below its vehicles.

Meanwhile, Toyota, Nissan, and a variety of cell makers are engaged on solid-state battery tech that will additionally permit such super-fast charging. And Volvo’s cousin Polestar is testing solid-state tech that would permit 100 miles restored in 5 minutes. But Lotus is amongst only a few corporations boasting DC quick charging above 400 kw with present liquid electrolyte battery codecs.
Volvo can also be launching an vitality enterprise, and the upcoming EX90 is its first EV that can have all the required {hardware} for bidirectional charging.
