Managing Heat in Modern Electronic Devices (Part 2)

By TriMech on February 25, 2019

In part one of this series, we evaluated how heat accumulation on a circuit board can lead to components shorting out and causing product performance issues. In this follow-up article and video, we're going to explore another important consideration when designing connected devices - battery life.

From the latest smartphone release to the driving range in electric vehicles, battery efficiency and performance is often a deciding factor in consumer purchasing decisions.
Thermal Management for Batteries

Heat flows out of batteries by convection, conduction and radiation. Ideally, you want to be able to account for any heat the battery may produce, either while in use or being charged, so that you stay within the optimum operating temperature.

In this video, we continue our experiment in designing our TriMech scooter prototype. Taking into account this rule of thumb - for every 10-degree temperature increase, overall battery life would decrease by half - we wanted to make sure that even at its peak operating condition the battery would stay cool to ensure long life.

We look at multiple battery types and based on our heat simulations ultimately came up with a battery pack design that could maximize power output while keeping the battery cool; ensuring that our scooter could stay charged as long as possible with a power source that would last for many cycles to come.
