A new solution for lithium-ion batteries is being introduced by ecovolta at the Energy Storage Europe in Dusseldorf. According to a press release, this reduces the risk of battery fires and cell explosions in e-mobility applications.
When a battery pack suffers mechanical damage, a high current initially flows through the affected region and the temperature rises locally. In conventional battery solutions, the cell is impacted directly, which could lead to explosions and battery fires. With ecovolta battery packs, the temperature rises locally at the cell junction in the case of mechanical damage. This junction then melts, separating the damaged cell from the intact components. The rest of the pack therefore remains functional, the company reports.
According to the press release, this new safety concept is incorporated in all ecovolta traction batteries. This allows for capacities ranging from ten watt-hours to several hundred kilowatt-hours and voltages of 12 to 600 volts as well as any desired battery shape
“This ecovolta concept offers e-mobility suppliers a battery solution that makes the highest safety standards economical even for small and mid-sized vehicle series,” says ecovolta CTO Paul Hauser.
