The power-off protection function of the charger is one of the core protection designs. This function can promptly cut off the power supply in case of abnormal current, unstable voltage, equipment overload,

There is a direct correlation between charger power and cable specifications. Power determines the output current and voltage, while cable carrying capacity affects the stability of current transmission efficiency. High power chargers need to be paired with cables that meet specifications to ensure smooth current conduction, prevent cable overheating, increased losses, or energy loss.

As a basic accessory of modern electronic devices, chargers are widely used worldwide with different types of plugs. The diversification of plug standards stems from the differences

　The performance of battery chargers is influenced by multiple parameters, among which the input voltage as the power supply basis is often misunderstood as\' higher, better \'. In fact, the higher the

　The trend towards multifunctionality is driving continuous optimization of charger products, and battery chargers equipped with USB interfaces are gradually becoming mainstream options. Compared

　The types of batteries are constantly evolving, and charging technologies are also becoming more diverse. As two widely used types of rechargeable batteries, nickel hydrogen batteries and lithium batteries

The phenomenon of heat generation during the use of battery chargers is a common physical manifestation.The cause of heating is usually related to the operation of internal circuits

The phenomenon of heat generation during the use of battery chargers is a common physical manifestation.

　Battery expansion is usually caused by excessive gas generated inside the battery during the charging process,leading to the expansion of the battery casing.This phenomenon is common in lithium batteries and is mainly caused by the following reasons.

The overcharge protection mechanism of the charger is a key function to ensure that the battery is not overcharged during the charging process.Overcharging refers to continuing to charge a battery when its voltage reaches or exceeds its rated voltage,which can cause excessive pressure inside the battery,potentially leading to potential hazards such as battery

　Lithium ion batteries and lead-acid batteries are common types of rechargeable batteries,and they have significant differences in charging principles,charger design,charging voltage,and current requirements.

To determine whether there is an internal circuit problem with an electric vehicle charger,observation and testing can be carried out from the following aspects:
