Technical FAQs 4

What is a PTC battery?

PTC devices are commonly used in lithium-ion cells for consumer electronics, electric vehicles, and other applications. In addition to providing safety benefits, they can also improve battery performance by reducing the risk of overcharging and over-discharging.

What is a PTC thermistor?

A Positive Temperature Coefficient (PTC) thermistor is a type of resistor whose resistance increases as the temperature rises. These clever little devices react to temperature changes, which is precisely why they play a critical role in battery systems.

What is PTC used for?

This characteristic makes PTC widely used in battery packs (such as the motorcycle battery packs), power management, motor control and other fields. Temperature control: PTC can also be used for temperature control. For example, in new energy vehicles, PTC is often used as a device to provide auxiliary heating for batteries and motors.

What is a PTC device in a lithium ion cell?

A PTC device is a type of resistor that exhibits a sharp increase in resistance when the temperature rises above a certain threshold. In a lithium-ion cell, the PTC device is placed in series with the positive electrode. During normal operation, the PTC device has low resistance and does not significantly affect the battery's performance.
