Dynamic crash tests to demonstrate battery safety performance in simulated accidents
TÜV SÜD supports its customers in the area of battery crash tests with long-standing experience, expert know-how and reliable tests. We are able to perform dynamic impact tests for electric vehicle batteries and provide advice on the optimum test design. All tests are conducted at our various crash test facilities, which utilise impactors with variable mass and geometry.
Crash tests simulate realistic accident scenarios to obtain substantiated information about the safety of the batteries when the vehicle body becomes deformed in an accident. The tests are performed in the dedicated crash test facility. Various test methods with different acceleration and speed profiles are used as requested and required by customers. After completion of the tests, a comprehensive technical test report is issued to the client.
This is with an aim to assess how high-voltage batteries in electric vehicles – also known as rechargeable energy storage systems (RESS) – respond in accidents. As electric vehicles pose a potential threat to the safety of drivers and passengers through car accidents, testing rechargeable batteries is essential for automotive manufacturers and suppliers as well as battery OEMs.
Only crash tests supply substantiated information on how batteries will respond in case of an accident and can deliver various benefits:
TÜV SÜD supports its customers in the area of crash testing with long-standing experience, in-depth know-how and, first and foremost, highly professional and reliable tests.
As your globally recognised partner, TÜV SÜD offers electric car battery crash tests according to different test methods depending on customer requirements. At our crash centre in Oberpfaffenhofen, near Munich, Germany, dedicated automotive and battery experts support customers with the development and optimisation of their products. This process ensures maximum electric vehicle battery safety.
Our battery crash test centre in Oberpfaffenhofen and other global locations offer the following test services:
Within the scope of these tests, the batteries are exposed to defined crash pulses or loads as required by the relevant standard, e.g. ECE-R 100. For this purpose, the battery is fastened to a sled, which generates the required shock during deceleration including elements of deformation.
The deformation of a battery is typically very random in the real world, which increases the difficulty of predicting and determining battery resistance against dynamic loading during actual impact. Simulating a battery loading condition using impactors helps manufacturers to predict the behavior of stress condition sustained by batteries in various impact scenarios.
