The dynamic power allocation technology of the smart car charger is the core of achieving current adaptive balancing when multiple devices are fast charged at the same time. This technology uses the built-in intelligent control chip to monitor each connected device in real time, accurately capture the charging needs and current status of each device, and provide a basis for subsequent power allocation.
When multiple devices are connected at the same time, the control chip will first identify the fast charging protocol and maximum tolerance current of each device. Different devices have different battery capacities, charging stages, and supported fast charging standards. This information will be quickly parsed by the chip and converted into specific power demand parameters. Through this intelligent identification mechanism, the system can clearly identify the optimal current intensity required by each device at the current moment, laying the foundation for balanced allocation.
Based on the identified device needs, the dynamic power allocation system will start the dynamic adjustment algorithm. The algorithm will comprehensively consider the total output power limit of the smart car charger and the priority of each device - usually giving priority to devices that are in a low power state or in urgent need of charging. Within the range allowed by the total power, the algorithm will allocate appropriate current to each device to ensure that no device is damaged due to excessive current or charged slowly due to too little current.
When the charging state of a device changes, for example, a device enters the trickle charging stage from the fast charging stage, the system will quickly sense this change and adjust the power distribution. Part of the current originally supplied to the device will be redistributed to other devices that are still in the high power demand stage, so that the total power can be fully utilized, while ensuring that each device is always in the best charging state. This real-time adjustment mechanism allows the current distribution to be flexibly adapted as the device state changes.
In addition, dynamic power allocation technology also has load balancing capabilities. When multiple devices are fast charged at the same time and the total power is close to the upper limit, the system will fine-tune the current of each device to prevent the total current from exceeding the safety threshold. This fine-tuning is not a simple average distribution, but a differentiated adjustment based on the actual needs of the device, while ensuring safety, to maximize the charging efficiency of each device.
In order to achieve accurate current balance, the technology also incorporates a feedback adjustment mechanism. Each charging interface is equipped with a current monitoring module, which feeds back the output current data of each interface to the control chip in real time. The chip continuously corrects the power allocation instruction by comparing the actual output with the preset parameters to ensure that the current obtained by each device is consistent with the expected value, thereby achieving a long-term stable equilibrium state.
Through the above-mentioned multi-level collaborative work - from device identification and demand analysis to dynamic algorithm adjustment, load balancing and feedback correction, the dynamic power allocation technology of the smart car charger can always maintain adaptive current balance when multiple devices are fast charging at the same time, ensuring both charging efficiency and the safe operation of the devices and the smart car charger.
