Case Study: Team Bath Racing Electric achieves compliant battery cooling with Cadence Celsius EC Solver

Team Bath Racing Electric lowers accumulator temperature to 59°C with Cadence

Team Bath Racing Electric (TBRe), a student team from Bath University competing in the Formula Student electric vehicle challenge, needed to lower their accumulator battery temperature to comply with competition rules. Their previous methods could not accurately simulate thermal performance, leading to costly post-assembly testing. They turned to Cadence and its Celsius EC Solver thermal simulation software to address this challenge.

Using the Cadence Celsius EC Solver, the team identified a cooling flow flaw causing recirculation and high temperatures. They simulated design iterations, ultimately implementing heat sinks and capped subpacks to direct airflow efficiently. This solution, developed through rapid simulation, reduced the critical temperature from 63.4°C to 59°C, ensuring regulatory compliance and enabling a confident, optimized final design.
