BMS Benchmarking and Validation Services

Batteries are the costliest and the most vunerable part of any Electric Vehicles, Stationary Storage, Telecom, Consumer Electronics or Aerospace application. The Battery Management System (BMS) is designed to constantly monitor the battery and take corrective actions to get the best out out of it to keep it safe and fully functional over its entire life cycle. 

Having a reliable and high performing BMS-Battery combination can be the defining factor between a successful product and a field failure. A good BMS is like a nerve system that gets the best out of each drop of energy in a battery while a poorly designed BMS can not only spoil the batteries it can also lead to catastrophic failures, unsafe conditions and that may adversely affect your brand and your business. 

We at MakerMax offer BMS-BVS (benchmarking and validation services) to provide you the detailed data, information and analytics to help you chose the right BMS or upgrade your current BMS to get the best out of your batteries.

THe BMS-BVS process is outlined below

MakerMax BMS Benchmarking Flow
  1. We ask you to fill-up your Requirement form that will help us gather information about the BMS that you want to get validated. The online form provided at the bottom of this page will ask for information that helps us ascertain your stated needs and the gaps identified by you.
  2. In the Sample phase, we ask you to send us samples of the BMS to be able to give an exact quote for the complete project along with the deliverable at each milestone. Though we strongly recommend you to order a complete and comprehensive analysis, you can chose to what extent you want the deliverable. Our quotes start at INR 25,000 (USD 350) for a basic BMS and may go upto INR 100000 (USD 1500) for a complex/multi layered BMS.
  3. The formal signoff of the project takes place at this point alongwith the advance payment and the
    number of samples required for the project.
  4. In the Testing phase, the samples will be put on our testing rigs and subjected to graded tests under normal and extreme simulated conditions. Some important tests are listed below.
  • Probe testing

    A circuit block diagram will be created of the different sections of your BMS. This test will ascertain the health of the components and the connections as received from the supplier. If a schematic is available from the supplier, it will be much easier to perform this test. If it is not available, we will generate a circuit block diagram based on the probe test.

  • Component testing

    Here the individual components are tested for their specs, reliability and tolerances in their stated band of operations. With a vast variety and quality of components available in the electronic markets today, it is imperative to choose the right power rating, voltage rating, current rating and temperature rating  based on your end product application.

  • High voltage testing

    High voltage DC needs to be handled carefully on-board and off-board. We will test how well your BMS circuitry isolates high voltage from low voltage components. Are the trace widths appropriate to handle high voltage, and high currents. Any component failures that may compromise the isolation barrier will be identified.

  • Noise injection testing

    We will inject various frequencies of AC waveforms into different parts of the circuit to measure the noise immunity and response of the circuit to it. This is especially important when the BMS is operating inside a vehicle as noise propagates through high voltage lines from motors or switching elements causing un-intended behaviour of the circuit.

  • Thermal testing

    All components used in the BMS have a certain temperature range that is recommended for their operation. Testing is necessary in load and no-load conditions at different ambient conditions to see the response of the circuit elements.

  • Failure testing

    This test checks to see if there is failure in the circuit, how to mitigate the repercussions. A small element such as a decoupling capacitor can also cause a complete circuit failure if it fails during operation, such vulnerabilities need to be identified and fixed.

A comprehensive Report will be prepared on the tests and results along with the list of tests conducted, data that was collected, pass / fail reports, points of concern, comparison charts with other BMS systems, comparison with the industry standards, and a detailed breakdown on the different parts of your selected BMS. This will be like a comprehensive health check report on the important components of the BMS.

Our report will come with Recommendations – we will prepare a priority wise list of recommendations of improvements for better performance of your device and the safety of your end product.

7. In case you desire, we can carry out the implementation of the recommendations as well. A separate contract will be agreed upon for Technical Design Services (TDS), in case you wish us to implement end-to-end or a part of the recommendations for your BMS.
