Nowadays, intelligence is being recognized by more and more countries and auto companies as the direction of future auto industry development. The global auto industry is now entering the era of transformation and upgrading based on electrification and intelligence. While entering the runway of smart cars, many traditional automobile manufacturers in China and Internet companies such as Baidu have invested heavily in recruiting high-level talent and developing smart car technologies from around the world. "The battery, motor, electronic control and vehicle system of China's new energy automotive industry all have strong international competitiveness and have laid a solid foundation for the sustainable development of smart vehicles."
The on-board charger refers to the on-board charger powered by the car battery (car 12V, truck 24V), and is widely used in the charging of lithium batteries for various portable and handheld devices. Car charger must consider the actual demand of lithium battery charging (constant voltage CV, constant current CC, OVP overvoltage protection), but also take into account the harsh environment of the vehicle battery (transient spike voltage, system switching noise interference, EMI, etc.); Therefore, the power management IC selected by the vehicle charging solution must satisfy the requirements of high-voltage, high-efficiency, high-reliability, and low-frequency (in favor of EMI design) switching power supply chips.
The car charger is an accessory for charging the digital product anytime and anywhere for the owner to use the vehicle car charging source. Some high-end car chargers generally include two USB ports that can charge two digital products simultaneously. This kind of product generally has overload protection, the car charger has short circuit protection, high voltage input protection, high temperature protection, four safety protection functions to ensure safe use. The car charger can also be used at home for car use, achieving three-in-one multi-purpose use for car charging, direct charging, and USB charging.
