What is the core of the problem?

Battery packs are usually tightly “packed” and sealed with performance and safety as primary objectives. The packs are very rarely designed for maintenance. Octave develops smart second life battery packs for stationary storage. Maintenance is (even) more important as modules will need to be replaced more frequently. Ideally, the replacement of a module can be done directly by the client without intervention from an electrician or specialized engineer!

What would be the impact if this problem were to be fixed?

Easy maintenance is key in Octave’s product and service offering and it will contribute to making second life battery storage commercially viable. This way, we can avoid the unnecessary production of new batteries and contribute to a healthier planet!

Why are you submitting this challenge?

We are looking for fresh ideas from bright students to crack this complex problem.

In what ways have there been attempts to solve this problem?

Octave is currently developing the design of its products and is taken into account maintainability as much as possible. We have opted for a rack with easily accessible battery modules and for our larger systems we will opt for a distributed architecture with parallel strings so an individual string can be switched off for maintenance while the rest of the system can continue to operate. Also, we have spent significant efforts on developing individual monitoring of our battery modules so we can anticipate when a module has to be replaced.

What are the next steps that need to be taken?

The next steps that we would recommend are linked to the physcial replacement of an individual module: how can we design a structure and procedure that make it easy, intuitive and safe to replace a module. Traditionally, modules are connected via busbars that are tightly screwed onto the connectors. Modules are also equipped with at least one voltage sensor that would need to be removed. This being said, we do not want to limit the problem solving in any way!
