[0002] An automotive battery charger, as a charging device specifically designed for automotive batteries, its core lies in converting alternating current (AC) into direct current (DC) suitable for battery charging. This process is usually achieved through high-frequency switching power supply technology, using DC / DC converter topologies such as full-bridge or half-bridge to convert the input AC power into a stable DC output. During the conversion process, key components such as transformers and power semiconductor devices (such as IGBTs or MOSFETs) play an important role, ensuring efficient power conversion and stable output.

[0003] For existing automotive battery chargers, to ensure the overall heat dissipation effect of the charger, it is necessary to perforate the charger, resulting in poor overall waterproof performance. When charging in rainy weather, rainwater is likely to enter the charger through the heat dissipation holes and wire connection holes, causing damage to the entire charger.
