German firm Batteryuniversity (BU) has introduced new test benches capable of testing the largest EV batteries.
BU’s new 120 kilonewton shaker can handle a weight of 800 kg, and can test random profiles, sine sweep, superimposed sine and shock impulses. Frequency can be set between 5 and 2,500 hertz.
A large low-pressure chamber (8x3x3 meters) allows testing of huge battery units or other components. “With the new test benches, we are expanding BU’s services for our customers in the automotive sector. With the shaker and the low-pressure chamber, we can also test components from the aerospace sector,” says the head of Batteryuniversity, Dr. Jochen Mähliß.
BU offers electrical testing of large battery units during the development process. Using special test circuits, battery units of up to 850 V and 1200 A can be charged and discharged. Maximum power is 350 kilowatts. Four smaller battery circuits can be interconnected to achieve 2,400 amperes.
BU is an accredited testing laboratory for battery and environmental tests, and also offers training programs for battery developers and users.
“BU has invested €1.4 million in the new devices. It is therefore well-positioned for the future of battery testing in the field of electric mobility,” says Sven Bauer, Managing Director.
