How Does Wired Fast Charging Work and What Technologies Are Involved?
Wired fast charging works by increasing the rate at which electrical energy flows from the charger to a device’s battery. This process involves several technologies and components. First, a compatible power adapter delivers higher wattage compared to standard chargers. Second, the charging cable must support this increased power level. Third, the device’s charging circuitry must be designed to accept fast charging.
When a device connects to a fast charger, the power adapter identifies the device’s capability to handle faster charging. It communicates this through a protocol called Power Delivery (PD) or other fast charging standards. These protocols allow the charger and device to negotiate the optimal voltage and current.
As the charging begins, the voltage may be increased while managing the current to maximize power flow without overheating the battery. This process often involves a feature called Battery Management System (BMS), which monitors the battery’s temperature and charge level to prevent damage.
Once the battery reaches a certain charge level, the system adjusts the power flow to slower rates to ensure safety and prolong battery life. In summary, wired fast charging efficiently delivers more power by using intelligent communication between the charger and device, advanced charging cables, and safety monitoring systems.
