QuantumScape and Volkswagen EV battery passes endurance test

QuantumScape’s new solid-state battery for electric vehicles has exceeded expectations in its first endurance test

In an endurance test run by PowerCo, the battery arm of Volkswagen Group, the battery achieved more than 1000 charging cycles with still more than 95 per cent capacity.

The Volkswagen Group says this will offer motorists longer ranges on a single charge, shorter charging times and a safer experience for their electric vehicles.

PowerCo CEO Frank Blome says the initial tests showed positive signs for the future of the technology.

“These are very encouraging results that impressively underpin the potential of the solid-state cell,” he says.

“The final result of this development could be a battery cell that enables long ranges, can be charged super-quickly and practically does not age.

“We are convinced of the solid-state cell and are continuing to work at full speed with our partner QuantumScape towards series production.”

Volkswagen Group and QuantumScape reported that the solid-state cell battery greatly exceeded the industry-standard targets laid out for electric vehicle batteries, needing to meet 700 charging cycles and a maximum capacity loss of 20 per cent.

QuantumScape CEO Jagdeep Singh was encouraged by the test results.

“These results from the Volkswagen Group’s PowerCo testing make clear that QuantumScape’s anodeless solid-state lithium-metal cells are capable of exceptional performance,” he says.

“While we have more work to do to bring this technology to market, we are not aware of any other automotive-format lithium-metal battery that has shown such high discharge energy retention over a comparable cycle count under similar conditions.

“We’re excited to be working closely with the Volkswagen Group and PowerCo to industrialize this technology and bring it to market as quickly as possible.”

While there are still more tests to be conducted on the batteries, the Volkswagen Group says the next step in the process is to perfect and scale the future manufacturing process.
