Samsung SDI shows fast charging battery for electric cars
A lineup of various battery cells for electric vehicles (EVs) and plug-in hybrid electric vehicles (PHEVs) come in 37, 50, 60 and 94 Ah capacities with a range of 600km after just a 20-minute charge.
The company is also showing its recently introduced battery technology based on 3D “graphene balls” that enable a 45 percent increase in capacity and five times faster charging speed as well as its latest solid state batteries.
Multi-Functional Module Battery Packs allow designers to adjust the number of modules to capacities they need and to diversify driving distances capabilities from a single pack as the foundation for an entire vehicle platform. This includes the “Low Height Cell” whose height has been reduced by more than 20 percent from existing cells. By using this cell design the automotive companies can increase the interior space of an EV and increase design flexibility for the vehicle overall.
Samsung SDI also displayed cells and modules based on the new 21700 standard cylindrical battery. This is 21 mm in diameter and 70 mm in height with capacity that is 50 percent larger than 18650 battery technology. Its size is optimal for maximizing power output as well as battery life and Samsung SDI says it is set to be the next standard for applications in Energy Storage Systems (ESS), electric power tools and electric vehicles.
“We will lead the popularization of electric vehicles by developing products based on cutting-edge technology which will in an optimum manner meet the needs of our customers and the market,” said Jeong Seh-woong, executive vice president of automotive business and ESS business of Samsung SDI. “We will continue to lead global market as the world’s top technology company providing total solutions for EV battery applications.”
