Picture of our Lead Battery Engineer Arpit



Arpit is the model maker at TWAICE. His works are not miniature landscapes, but rather virtual images of batteries. He makes digital twins of modern lithium-ion batteries, as they work in e-vehicles. With the help of such a model, Arpit can simulate future operating conditions of the battery. “If, for example, a car owner asks how long his battery will last, we can tell him exactly,” explains the TWAICE Lead Battery Engineer. For developers and users, this is a great advantage because they still know little about the state of health of modern energy storage.

The TWAICE software calculates the state of health now based on previous battery usage. This varies depending on the driver, climate or vehicle. The program uses the well-established usage data to simulate how the energy storage device will behave in the future and how it could be optimized.

The modeling of batteries was already the subject of Arpit’s thesis, which he completed in early 2018 in Eindhoven, the Netherlands. His studies led the native Indian across Europe: Sweden, Italy, the Netherlands, Germany: Everywhere the 32-year-old has been researching the nascent technology of battery modeling. The position at TWAICE is exactly what he wants and he is happy to be able to apply his unique knowledge. “Had I returned to India, I would have largely lost my knowledge. The battery technology there is far behind compared to here, “he says.

But Arpit also faced some administrative problems in Germany: Bank account opening and housing search are not so easy out of Italy. The work permit came only months later, even though the company urgently needed it.

Such initial difficulties are forgotten today and the modeling specialist is happy in Munich. “My first experience within the company was a mountain trip together – that was great,” he recalls. In his work, he wants to “make a difference and not be a small number among many others,” he says. Therefore, an application to a large company would never have been imaginable, neither here nor in India. “I have a lot more freedom here, I need that,” says Arpit.
