Chroma 17040E Battery Tester

Chroma 17040E Regenerative Battery Pack Test System

Chroma 17040E Regenerative Battery Pack Test System is a high-precision system specifically designed for secondary battery module and pack tests. The energy regenerative function greatly reduces power consumption during discharge, and ensures a stable power grid without generating harmonic pollution on other devices - even under dynamic charge and discharge conditions. Where traditional equipment discharges waste energy in the form of heat, Chroma 17040E can recycle the electric energy discharged by the battery module back to the grid, thus reducing waste energy and alleviating HVAC requirements.

The 17040E has built-in parallel channels and dynamic profile simulation functions. The parallel capability maximizes the charge and discharge current and power, thus increasing the efficiency and flexibility of equipment utilization. The dynamic profile simulation allows users to load a battery waveform of a given drive profile in either current or power mode to meet the NEDC/FUDS requirements.

Its bidirectional architecture assures uninterrupted current during the charge and discharge transient state so that the driving conditions can be accurately simulated in line with the ISO, IEC, UL, and GB/T international test standards.

Equipped with Chroma's powerful Battery Pro software, the test system offers flexible test editing functions to perform independent channel tests, and conforms to various requirements for testing secondary battery packs with high safety and stability.

Chroma 17040E ensures protected charge/ discharge testing through multiple safety features including Over Voltage Protection, Over Current Protection, Over Temperature Protection, and external parameter detection. The recovery functions prevent that test data is interrupted or lost in the case of power failure.

Specifically designed for secondary battery module and pack tests, Chroma 17040E Regenerative Battery Pack Test System offers ultimate precision, safety, and efficiency. The main features include recycled energy, parallel channels, high power for battery applications, and high accuracy in voltage and current measurement as well as drive cycle simulation.

High-precision Measurements for Improved Product Quality

The auto voltage/current range function switches between multiple ranges. When there is a dynamic change between large or small currents, the test system automatically adjusts to the right range to optimize the measurement accuracy.

• Voltage accuracy: ±(0.02% of rdg. ±0.02% of F.S.)
• Current accuracy: ±(0.05% of r.n.g.)

High-frequency Sampling for Battery Pack Capacity Capture

The high-frequency sampling measurement technology reaches a 50kHz sampling rate to ensure dynamic measurement accuracy. Other battery chargers and dischargers use software to read current values for power computing; however, limited data sampling speed could result in large errors when calculating the dynamic current capacity. Chroma increased the V/I sampling rate and added a double-sampling integrator, so the 17040E test system is able to provide capacity calculation with much higher accuracy. When the current changes, the data is not lost and the transmission speed is not affected.

• V/I sampling rate: 50KHz (per 20µs)

Quick Response Testing for Battery Pack Limit Verification

Chroma 17040E supports dynamic driving profile simulation (waveform), which simulates the current and power states of actual driving conditions to comply with NEDC, FUDS, and HPPC standards. The quick current response enables optimized charge/discharge switch control; the current is smooth without overshoot to avoid damage to the battery.
