Environmental control measures involve controlling the temperature of the surroundings where lithium batteries are used or stored. This includes maintaining ambient temperatures within the optimal range of 15°C to 35°C (59°F to 95°F). Avoid exposing batteries to extreme temperatures, such as in hot cars or direct sunlight.
What is a thermal management system in a lithium battery?
Thermal management systems help regulate the temperature of lithium batteries during operation. Typical systems include heat sinks, cooling fans, thermal pads, and temperature sensors. Heat sinks dissipate excess heat from the battery to prevent overheating. Cooling fans improve airflow around the battery, aiding in heat dissipation.
