How to Measure Voltage Rise Time in Battery Testers: A Practical Guide

Electrazine Media

What You’ll Learn:

  • How to measure rise time for power sources
  • Understanding voltage vs. time signal measurements using an oscilloscope
  • Practical steps for setting up a battery testing configuration

When testing a DC power supply, a common question often arises: “What is the rise time of a voltage source when applying a specific voltage under load?” Recently, I was tasked with determining the rise time of a power source transitioning from 0 to 350 V under a 400 mA load. Although the power source’s rise time specification was clearly stated as 0 to 600 V at 2.6 A over 250 ms, my scenario had different parameters. The challenge was to measure the performance of the voltage source under these new conditions.

Understanding Rise Time and Its Importance

The rise time of a power source is the time it takes for the voltage to transition from a lower to a higher level under a load. In my case, the task was to assess the rise time for a 0 to 350 V step with a 400 mA load. The initial specifications for the power source mentioned a 250 ms rise time for a 0 to 600 V transition at a 2.6 A load. Given that the voltage and current requirements for my test were lower (about 60% of the voltage and 15% of the current), it was logical to expect a faster rise time, but by how much?

How to Measure Voltage Rise Time in Battery Testers: A Practical Guide 11

Setting Up a Voltage Rise Time Test

Setting up this test requires more than simply connecting the power source and measuring the output. Proper configuration is essential to avoid damaging the equipment or obtaining incorrect readings. The following steps outline how to set up the test properly.

Step 1: Configuring the Test Setup

To measure the rise time of a battery tester, a test configuration is needed that includes both the power supply (device under test, or DUT) and a load capable of drawing 400 mA consistently. A measurement device, such as an oscilloscope, will capture the output voltage waveform.

Choosing the Right Load

For this test, the load must draw 400 mA while the power source transitions from 0 to 350 V. The simplest option is a resistor. Using Ohm’s Law (R = V/I), the required resistance is calculated to be 875 ohms. However, this resistor must also handle a significant amount of power, around 140 W (P = I²R).

While a resistor can achieve the desired current at 350 V, it won’t draw 400 mA consistently as the voltage rises from 0 to 350 V. For example, at 175 V (halfway to 350 V), the current would only be 200 mA. Therefore, a constant current load, such as an electronic load (eload), is a better choice for this application.

Using an Electronic Load (Eload)

An eload can ensure a constant current of 400 mA throughout the voltage rise. However, finding an eload capable of operating at such high voltages (350 V) can be challenging, as many are not rated for this range. Additionally, most eloads have a minimum operating voltage, typically around 2 V, which must be met for the eload to function correctly.

Step 2: Performing Voltage vs. Time Measurements

Once the proper load is in place, the next step is to measure the voltage rise over time. For this, an oscilloscope is the most practical tool, as it can display the voltage waveform in real-time.

Why Use an Oscilloscope?

A digital multimeter (DMM) may be tempting to use for this measurement, but it cannot capture time-varying signals. An oscilloscope, on the other hand, can accurately display the voltage waveform, allowing you to measure the rise time directly from the screen.

High-Voltage Considerations

Because the voltage being measured is quite high (350 V), a high-voltage probe is necessary. Additionally, you may want to measure the current to confirm that the 400 mA load is maintained during the rise time. This will require a current probe for the oscilloscope.

Grounding Issues

Oscilloscopes are ground-referenced, meaning they connect to the ground when measuring the DUT. In cases where the DUT floats with respect to ground, this can create a grounding path that could damage the oscilloscope or other equipment. Care must be taken to avoid unintended grounding, which could result in shorts or even catastrophic damage.

Step 3: Alternative Measurement Devices

If using an oscilloscope presents challenges due to the high voltage or grounding issues, other instruments like a power analyzer can be used. A power analyzer can measure both DC and AC waveforms and often does not require a separate current probe. Additionally, it is not ground-referenced, making it safer to use in certain setups.

Practical Setup: Using a Two-Quadrant Power Supply

How to Measure Voltage Rise Time in Battery Testers: A Practical Guide 12

For this test, we opted to use a two-quadrant power supply rated at 500 V and ± 20 A. Although this power supply offers more power than required, it easily handles the test voltage and accurately maintains the 400 mA constant current. Additionally, this supply features a built-in digitizer, eliminating the need for an oscilloscope, high-voltage probe, or current probe.

The setup was controlled through companion software, which provided a user-friendly interface for visualizing the voltage and current waveforms.

Measuring Voltage Rise Time: Results

Using the companion software, we captured the voltage rise time and analyzed the results. The voltage trace clearly showed the transition from 0 to 350 V, with the rise time measured at 77 ms—significantly faster than the original 250 ms specification at a higher load.

Interestingly, during the initial part of the test, while the DUT was at 0 V, the current was not regulated as the eload could not maintain the 400 mA until the voltage rose above 2 V. Once the voltage began to rise, the current briefly overshot 400 mA before stabilizing.

Conclusion: Key Takeaways for Battery Testing

Measuring the rise time of a power source is an essential step in understanding its performance, especially when testing battery modules. By carefully selecting the right equipment, such as a constant current eload and an oscilloscope (or power analyzer), accurate and safe measurements can be made.

In this test, the rise time was successfully measured at 77 ms, much faster than the original specification under higher voltage and current conditions. This demonstrates that even with less stringent conditions, accurate measurements are crucial for reliable testing outcomes.

“By simply scanning the QR code with their smartphone, customers can access a digital menu of services,” Niermann explains. This menu includes direct access to the service department, as well as additional features such as drive-specific documentation, life cycle services, and the latest product or firmware updates. The paperless nature of this system also contributes to resource savings. While the company still provides physical documentation for specific requests or ATEX products, this digital transformation offers an eco-friendly and efficient alternative for most customers.

Easy Access to Spare Parts and the myNORD Portal

Beyond offering service support, the digital solution provides customers with immediate access to a list of potential spare parts tailored to their individual drive system. Customers can reach out directly to their assigned technical support or sales teams and gain instant entry to the myNORD customer portal. The serial number of the drive component is automatically pre-entered, streamlining any further actions. In addition, parameter data is securely stored via the NORDCON APP with NORDAC ACCESS BT, making it easy for customers to retrieve information whenever needed.

By embracing digital services, NORD DRIVESYSTEMS continues to enhance the customer experience, making it easier, faster, and more sustainable to access vital product information and support. Visit Here

Rohde & Schwarz has successfully completed the re-certification of its EU eCall testing solution, conducted by the independent testing organization cetecom advanced. This accomplishment highlights the dedication of both companies to delivering Next Generation eCall test solutions that adhere to standards, solidifying their status as leaders in the industry.

The newly implemented eCall Delegated Regulation (EU) 2024/1180, effective from May 9, 2024, introduces updates for 2G and 3G circuit-switched (CS) eCall systems. In response, Rohde & Schwarz has upgraded its R&S CMW-KA094 eCall end-to-end (E2E) conformance testing solution to align with the latest eCall regulations and standards, including EN 16454:2023. This enhancement will assist manufacturers and suppliers in fulfilling new compliance requirements, ensuring smooth integration of in-vehicle eCall systems (IVS).

The re-certification conducted by cetecom advanced verifies that the R&S CMW-KA094 eCall test software, which simulates a public safety answering point (PSAP), effectively meets the requirements for processing eCalls, receiving emergency data, and interacting with in-vehicle eCall systems. This positions manufacturers and suppliers utilizing the Rohde & Schwarz solution advantageously for acceptance tests of their emergency call systems and demonstrates Rohde & Schwarz’s commitment to providing comprehensive and dependable eCall testing solutions.

Furthermore, Rohde & Schwarz and cetecom advanced have agreed to continue their collaboration to develop a standard-compliant testing solution for Next Generation eCall, utilizing 4G and 5G network infrastructure for laboratory testing. cetecom advanced, designated as a technical service provider for eCall, supports ongoing revisions of relevant Next Generation eCall standards from CEN, such as EN 17240, EN 17184, and EN 16072. With a rich history in eCall testing, certification, and standardization, cetecom advanced has chosen the R&S CMX500 as the testing platform for Next Generation eCall conformance tests. The R&S CMX500 features an internal IMS server with MSD support via SIP, VoLTE/VoNR testing for eCall services, and unique capabilities for IP and application testing.

Through the collaborative validation of the R&S CMX-KA098 Next Generation eCall testing software by Rohde & Schwarz and cetecom advanced, customers gain access to a compliant testing solution that meets the latest CEN standards for Next Generation eCall. This will facilitate the transition to Next Generation eCall, which will become mandatory for all vehicle suppliers operating in the European market starting in 2026.
