ECE R100 Battery Tests

The safety and durability of high-voltage battery systems used in electric and hybrid vehicles must be validated in line with international regulations. ECE R100 is a key regulation that evaluates the safety, durability, and environmental performance of electric vehicle battery systems.

In our laboratory, we perform durability, charge-discharge, climatic, and mechanical vibration tests on battery systems in accordance with ECE R100 requirements. These tests provide a detailed analysis of the performance, safety, and durability of battery packs under real operating conditions.

Endurance and Charge-Discharge Testing

Endurance and charge-discharge tests are applied to evaluate the long-term performance of battery systems. During these tests, battery packs are subjected to repeated charge and discharge cycles, and their performance is monitored under long-term operating conditions. By simulating cyclic energy demands that represent real-world usage scenarios, the long-term behavior of the battery system is evaluated.

Throughout the test, the battery’s capacity change, internal resistance behavior, energy efficiency, and thermal performance are continuously tracked. This provides comprehensive data on the long-term reliability and performance stability of the battery system. Endurance tests are critical for determining whether electric vehicle batteries will operate safely and stably throughout their service life.

Environmental / Climatic Testing

Electric vehicle batteries must operate safely in different geographic regions and various climatic conditions. For this reason, battery systems are exposed to different environmental conditions during climatic testing, and their performance is evaluated.

In our laboratory, climatic tests expose battery systems to high and low temperature conditions and environments with temperature changes. During this process, the battery’s resistance to environmental conditions, its electrical performance, and its safe operating behavior are examined in detail. Climatic testing confirms that battery systems can operate safely and stably under different temperature and environmental conditions.

Mechanical Tests (Vibration)

Electric vehicle batteries are exposed to various mechanical vibrations from road conditions throughout the vehicle’s service life. Vibration tests under ECE R100 evaluate the resistance of battery systems against these mechanical loads.

During vibration testing, battery packs are tested under vibration profiles that represent real vehicle use. The mechanical integrity of the battery modules, the reliability of electrical connections, and the structural durability are analyzed. The tests confirm whether the battery system can operate safely under mechanical stresses caused by vibration.
