Dynamic crash tests to demonstrate battery safety performance in simulated accidents

//Contact us

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.

WHAT IS A BATTERY CRASH TEST FOR ELECTRIC VEHICLES?

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.

WHY IS EV BATTERY TESTING IN SIMULATED ACCIDENTS IMPORTANT?

Only crash tests supply substantiated information on how batteries will respond in case of an accident and can deliver various benefits:

Gain reliable insights about the safety performance of batteries installed in vehicles with battery crash tests as the only valid source.
Discover important information about your product through an established method of dynamic impact tests as early as possible in the development stage to make it more accident-proof.

Avoid rework and gain test results that validate your product development, type approval and conformity of production testing (CoP).
Obtain consumer confidence through test reports that validate you have completed extensive battery crash test simulations.

WE ARE YOUR PARTNER FOR TESTING THE SAFETY OF RECHARGEABLE BATTERIES IN CRASH TESTS

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 CRASH TEST SERVICES ACCORDING TO ELECTRIC CAR BATTERY SAFETY STANDARDS

Our battery crash test centre in Oberpfaffenhofen and other global locations offer the following test services:

Non-destructive testing of batteries at speeds of up to 80 km/h

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.

Dynamic loading or deformation of the high-voltage battery structure using an impactor

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.
