High Voltage Battery Testing | Uncio

Hardware improvements aren’t the only route to better batteries. Test systems can also help to evaluate the overall system design and optimize its performance. See what else can help develop the high voltage battery testing with better battery modules and packs.

Importance of Battery Pack Testing

Lithium-ion batteries used in EV applications have a tough life, as they are designed for approximately a decade of use in most electric vehicles.

However, after the first five years of operation, they slowly degrade, subjected to extreme operating temperatures, hundreds of partial cycles per year, fast charging, and changing charge and discharge rates.

Therefore, it’s essential for today’s researchers, engineers, and manufacturers to understand the fundamentals of EV battery tests and the best approaches to ensure safety, product performance, and time to market.

Stages and Types of Battery Testing

Battery tests are performed at each phase of the product life-cycle, including R&D, manufacturing, and in-use, to evaluate the overall system design and optimize its performance.

Standard tests include drive-cycles, peak power capability, BMS software validation, and application-specific characterization tests.

The goal of testing batteries as an individual component or subsystem is to answer specific questions about the design or build. For example, how will the battery perform at different temperature levels? What will be the impact of mechanical vibrations on the battery packs? Or will unbalance in battery cell voltages during the charging and discharging process cause overheating?
