How to maximise the battery life of your IoT device

The technological landscape in the electronics industry is as fast-moving as it is exciting, and to stay ahead of industry trends, we’re collaborating with our network of supplier partners to deliver a compelling webinar series.

We’re excited to present the recap of the very first webinar in this series, which covers the challenging topic of how to maximise the battery life of your IoT device.

The Internet of Things (IoT) has the potential to affect all aspects of our lives, and designers need to measure, simulate and model battery lifecycles in the presence of very small current requirements – quickly and accurately.

Expertly led by Chris Godfrey, Technical Marketing Manager at Tektronix, who is drawing on experience with manufacturers such as Ericsson Mobile Communications, Gerranti Technologies and Tunstall Group Components, this webinar in association with Tektronix will help you do just that.

Watch the video below if you’re an analogue design circuit engineer, test engineer, test technician or simply interested in understanding how to properly select and qualify low-power components or how to accurately and reliably measure power consumption and profile IoT batteries.

Armed with this information, you can take the first steps towards maximising the battery life of your IoT devices.

Questions and Answers

  1. How can I create a battery model that includes temperature as a factor?You can put the battery at a specific temperature – for example, in a temperature chamber – and create a model of the battery at the known temperature. That would give you a unique model based on a specific battery temperature.
  2. What is the maximum voltage and current that the battery simulator can output?The battery simulator can output 20V and 6A for a total of 120W. Thus the simulator can emulate a set of series or parallel batteries up to 20V with 6A current capacity.
  3. If I am sampling a lot of data to capture a battery drain current profile, how fast can I transfer data to a PC so that I do not lose any data?With the DMM7510, data can be sampled and streamed into a PC at a rate between 80,000 readings/s and 100,000 readings/s. Our Application Engineers can help with providing example code.
  4. I expect my battery to run for at least a year, how can I create a model for the battery without waiting such a long time?Create a model in which the battery discharges over a few weeks. That approximation may be close enough. If you want to test your product when the battery is near end-of-life conditions, the model conditions would be not significantly different whether the battery discharged over a few weeks or over a year.
