Without OCP, a faulty charger could overload the device, leading to catastrophic failure.
-
Over-Temperature Protection (OTP)
Over-temperature protection monitors the temperature of the charger and the device, preventing overheating. Excessive heat can damage internal components, reduce battery lifespan, or even pose a fire hazard. OTP mechanisms reduce or shut off the power supply if the temperature exceeds a safe limit. For example, if the charger’s internal temperature rises above a pre-set threshold, OTP would reduce the power output or completely disconnect the charger from the power source. This prevents thermal runaway and safeguards both the device and the surrounding environment.
-
Short-Circuit Protection (SCP)
Short-circuit protection safeguards against short circuits, which can occur due to damaged cables, faulty connectors, or internal device malfunctions. A short circuit creates a low-resistance path for current flow, resulting in a rapid surge of current that can cause severe damage. SCP mechanisms detect short circuits and immediately cut off the power supply, preventing catastrophic failure. For instance, if a damaged cable creates a short circuit, SCP would instantaneously interrupt the power flow, preventing the device and charger from being damaged. Absence of SCP significantly increases the risk of fire or electrical shock.
