It has a built-in safety feature which disables charging in case of unexpected high or low voltage. And, intelligent functions such as short-circuit and reverse connection protection, auto-adjustable charge current, and auto-restart after temporary fault ensure the charger is safe to use and operate.

The BQ2004HPN is designed to save energy and increase performance efficiency. It is optimized for low power consumption and has a 0.5A charge current rating. This allows for longer and safer battery cycles and increased appliance performance. The BQ2004HPN also provides overvoltage protection, thermal shutdown and current limiting features, which further improves safety and energy efficiency.

Working Principle

The BQ2004HPN can be used to charge different types of batteries. It utilizes a pulsed constant current/constant voltage (C/CV) charging principle to charge Li-Ion/NiMH/NiCd/Pb-acid batteries. As soon as the battery is connected to the charger, the charger will adjust its charge current according to the battery’s state of discharge. The charger will then monitor the battery voltage in order to determine the battery’s charge level. When the battery voltage has reached the average voltage, the charger will switch to a Constant Voltage (CV) charging mode. This will ensure that the battery will not be overcharged.

The BQ2004HPN provides a variety of advanced safety features. It has built-in short circuit and reverse connection protection, as well as overcurrent, overvoltage and thermal protection features. This ensures that the battery is safe to use and operate. Additionally, the BQ2004HPN also has an auto-restart function in case of a temporary fault. This ensures that the device is always operating within safe parameters.

In summary, the BQ2004HPN is a high-precision battery charger offering precise, safe, and reliable charging for all types of batteries. It supports a wide range of battery types, including Li-Ion, NiMH, NiCd, and lead-acid batteries. It is designed for a variety of applications and provides advanced safety features, including short-circuit and reverse connection protection, auto-adjustable charge current, and auto-restart after a temporary fault. The BQ2004HPN utilizes a C/CV charging principle to charge Li-Ion/NiMH/NiCd/Pb-acid batteries, as well as other advanced safety features to improve safety and energy efficiency.
