Rapid development in IT technologies, especially in relation to products such as smartphones, tablets and laptops, has created the conditions for considerable growth in China’s consumer battery testing and certification market.

Robotic system for battery testing

The market is currently growing by 20% each year, reaching RMB 200 million in 2016.

Consumer battery testing mainly focuses on reliability, performance and safety. Its testing procedures are typically characterized by large sample numbers, long test durations, and strict environmental protection requirements. Despite the rapid growth in the demand for battery testing services, there are capacity constraints, not least laboratory efficiency and the need to conform to environmental considerations.

To overcome these restrictions, SGS has developed BATAS – Battery Testing Automatic System. This automated and robotic system for testing batteries is now found in SGS battery testing laboratories in China.

BATAS was developed by SGS’s EEC laboratory as a way to improve battery test efficiency, simplify workflows, enhance levels of consistency, and reduce both manual operations and the margin for error. It uses SGS’s copyrighted Safety Testing Automation System (STAS) as the control unit, allowing robotic arms to install/remove testing samples and operate the different testing devices. The system is able to automatically switch test items in different test locations, meaning it can function continuously.

Battery Testing Automatic System (BATAS) provides the following technical solutions:

  1. Transforming the test chamber’s opening and closing mechanism
    The doors of battery testing chambers (including altitude simulation/low pressure chamber, temperature chamber, etc.) are traditionally manual and mechanical. The addition of an electrical device means this mechanical operation can be executed automatically

  2. Transforming the test equipment’s communication system
    Most testing chambers and safety test instruments lack an interconnected communication function. BATAS streamlines the testing process with SGS converting equipment to meet the communication requirements

  3. System automation for battery precondition/overcharge/over-discharge
    The fixture design allows automatic loading and unloading of battery samples, with test data being collected automatically

  4. Chamber automation
    Battery samples are preconditioned and flow in batches to different chambers. Samples are fixed on material plates, allowing the robots to place the samples accurately according to the program

  5. Automated battery vibration/impact testing
    Robots transfer the battery samples to the vibration system or impact system and start the test. After the test, robots remove the samples and place them in the designated position

  6. Automatic warehouse monitoring
    Robots are responsible for loading and unloading samples to their specified positions. The system monitors the warehouse status in real time, preventing the possibility of sample collision

Through automation, BATAS reduces a laboratory’s workload, increases its security, improves consistency and makes each step of the process more coherent.

BATAS represents the next generation in consumer battery testing solutions. With the rapid development of new IT products creating increased demand for battery testing services, it is the ideal solution for battery manufacturers looking for efficient, accurate and safe testing solutions.
