[PTC Thermistor Application Case] Lithium-ion Battery

Introducing examples of lithium-ion battery applications, such as preventing thermal loss in other electronic components and printed circuit boards by reducing current.

Here are some examples of the use of PTC thermistors in lithium-ion batteries. Lithium-ion batteries, which are utilized in various fields, store a large amount of power, raising concerns about the risk of fire or explosion in devices due to excessive current caused by short circuits. PTC thermistors detect this excessive current and prevent thermal damage to other electronic components and printed circuit boards by reducing the current. Additionally, PTC heaters with self-temperature control functions are effective for fully charging lithium-ion batteries in cold conditions. PTC heaters warm the battery to an appropriate temperature and maintain it, ensuring it does not exceed the dangerous threshold of 60°C, where there is a risk of fire. [Use Cases] - Detecting excessive current in lithium-ion batteries and preventing thermal damage to other electronic components and printed circuit boards by reducing the current. - PTC heaters with self-temperature control functions are effective for fully charging lithium-ion batteries in cold conditions. - PTC heaters warm the battery to an appropriate temperature and maintain it. *For more details, please download the PDF or feel free to contact us.*
