Model 17010H

Battery Reliability Test System

Product Details

Chroma 17010H Battery Reliability Test System is a high-precision charge and discharge test equipment specifically designed for high current/high power performance testing. This system is suitable for performance evaluation, life cycle testing, and product selection of large Lithium-ion Battery Cells (LIB Cells), Electric Double Layer Capacitors (EDLCs), and Lithium-ion Capacitors (LICs).

The 17010H's energy recovery circuit architecture offers a marked improvement over traditional switching power supply equipment. It features high measurement accuracy/precision, high-speed current response, zero-crossover time for charge-discharge conversion, as well as multiple current ranges, which help battery cell experiments to enhance capacity test accuracy, improve performance parameter identification, and facilitate realistic dynamic current and power testing. In addition, Chroma 17010H has a 200% pulse current output function, a 300A single-channel continuous current, and provides a 30S pulse test current of 600A, which is beneficial to applications such as power capability and DC internal resistance testing which require short-term and high-rate test currents, while also reducing equipment purchase costs.

High-current life cycle tests highlight the importance of testing the equipment's energy conversion efficiency. Benefits include not only reduced power demand but also a large decrease in heat production. The control circuit operates at a relatively low temperature, effectively suppressing thermal drift and extending components' life cycles. In this way, the 17010H achieves accurate and stable test performance. Compared with linear circuit products, it offers more efficient energy conversion and higher power density, reduces power distribution requirements for laboratories, saves operating power and air conditioning costs, and improves space utilization.

Taking into account the diversity of battery cell products and experiments, Chroma 17010H features a channel parallel function with a continuous current up to 2400A and a pulse current up to 4800A, greatly improving the applicability of the system.

With regards to safety, each channel is additionally equipped with Level 2 V. Protection, and an independent measurement loop prevents battery overvoltage when a single component fails, enhancing testing safety. In addition, the system's product maintenance design has been improved: the circuit units are modularized and can be individually assembled and disassembled quickly, enabling convenient maintenance and channel backup.

Pulse Output High Current & High Power Function

Accurate output capability that meets test standards
Run power capability tests and driving simulations to test compliance of vehicle batteries with international standards. Test parameters for high-rate current and power are based on battery operating conditions (such as BEV, PHEV, and HEV) with an output time of 30S, which makes purchasing full-power equipment unnecessary. Chroma 17010H not only provides 200% rated pulse current and power output capability, but can also effectively save equipment costs and space

Energy Recovery Architecture

Chroma 17010H feeds the electric energy released during discharge back to the AC power grid, which greatly reduces the generation of waste heat, realizes green energy manufacturing with low carbon emissions, reduces power distribution requirements, and saves operating power and air conditioning costs.

  • Discharged energy is fed back to the regional power grid with a recovery rate of 75%
  • System feedback grid current's total harmonic distortion <5%

Fast Current Response Capability and Cero Crossover Time

Fast current response < 1.5 mS / 200% pulse current output < 2 mS
The fast current response provides ideal experimental conditions, reduces occurrence of cumulative errors during the fast-changing dynamic test, and obtains low-distortion data.

High Accuracy and High Precision

Accuracy is key to comparison of different channel data
Battery products often require multi-channel experiments for comparative analysis to ensure the accuracy of measured differences between different channels. The higher the accuracy, the easier it is to identify differences.

High precision improves data analysis efficiency
The inside of the battery is a complex electrochemical structure, and its characteristics are changed by the current, temperature, SOC, SOH and other experimental conditions. Initial changes are subtle and easily affected by the measurement stability of the equipment. High precision ensures measurement reproducibility and reduces measurement-caused data jumps, which is very helpful for the interpretation of the testing data.

  • Can perform battery cell 0V abuse test
  • Suitable for EDLC testing

Multiple Current Range Design

Automatically select suitable current range in constant current (CC) mode
Provides multiple current output and measurement ranges and is suitable for test plans covering both high current and small current

Automatically switch suitable current ranges in constant voltage (CV) mode
Supports automatic switching of current ranges in constant voltage (CV) test mode with no output interruption during the process, improving current resolution and consistency of the cut-off judgment

Independent Hardware Level 2 V. Protection

Level 2 V. Protection reduces the risk of voltage measurement failure
Accidents caused by large battery cells are unpredictable. In order to strengthen the safety of the experiment, an auxiliary voltage is independently set in each channel to protect the measurement circuit, which independently memorizes the protection parameters and operates autonomously. When an abnormality occurs, the output circuit is forcibly closed immediately.

Battery LEx Software

Battery Lab Expert (Battery LEx) is the testing software platform specially developed for battery cell testing:

  • Group testing: Multiple channels of the same experiment are grouped to simplify operations and execute up to 50,000 steps
  • Variable editing: Using the data from the external data logger for flexible programming and complex applications
  • Chamber integration: DI/DO amplification monitors the chamber's status and protection mechanisms in real-time

Project Browser
Create up to 500 projects and construct corresponding test plans according to different DUT types or requirements. The project browser allows for easy review or adjustment of the DUT specifications, waveform simulation data, and recipe content.

Recipe Editor
In the hierarchical editing structure (test plan → main recipe → sub-recipe), users can directly share existing recipes by replacing the DUT specifications or quickly complete a plan by flexibly combining existing sub-recipes. Easily create new recipes to meet various types of charge and discharge test applications.

Recipe Executor
The recipe executor adopts group management according to different test plans. All channels in the group will simultaneously start testing and display their real-time test status. When integrated with a chamber, each channel will automatically trigger a waiting mechanism, and the temperature control will not start until all the channels reach the same condition. When there are multiple groups in the chamber, they can be set to wait between groups.
