What is a Battery Thermal Management System?

A battery thermal management system (BTMS) is designed to maintain the battery temperature within an optimal range. This is crucial as extreme temperatures can significantly affect battery performance, safety, and lifespan. BTMS ensures that batteries operate efficiently, preventing overheating during high-demand situations and maintaining warmth in cold conditions.

Why Are BTMSs Important for Electric Vehicles?

Battery performance is influenced by temperature. Here are some key reasons why BTMSs are vital:

1. They help increase the battery's life span by preventing thermal stress.
2. They ensure the battery operates at its optimal performance level.
3. They enhance safety by managing risks related to overheating.
4. They contribute to better energy efficiency, which can extend the driving range of the vehicle.

How Do Different Countries Approach Battery Thermal Management?
