Learn MoreFor batteries to function optimally, they need to be in a temperature-controlled environment or be connected to a heating system, especially when the battery is in a cold environment. This is where battery heating elements are used. Battery heaters are devices that offer uniform or focused heating to a battery as necessary.
Higher battery pack temperatures can also result in performance degradation including loss of capacity and power. Loss of lithium and the reduction of active materials under high temperature is what results in loss of capacity, and increase in internal resistance is what contributes to loss of power.
This is where battery heating elements are used. Battery heaters are devices that offer uniform or focused heating to a battery as necessary. They are flexible yet robust, compact, and, most times, surface adherent. They find applications in crucial sectors such as defense, medical, telecommunication, aerospace, and more.
