1. The situation and principle of charging and using at the same time
1. Many portable power stations can be used while charging with solar panels. This is because they have a complete power management system inside. This system can handle the charging and discharging process at the same time and distribute the power reasonably. For example, when the solar panel converts solar energy into electricity and inputs it into the power station, the power management system will distribute the power according to the power status of the power station, the charging power of the solar panel, the power consumption of the external device and other factors.
2. Assume that a portable power station has 50% power left, a solar panel with a charging power of 50 watts is connected, and a laptop (power consumption of 30 watts) and a mobile phone (power consumption of 10 watts) are charging at the same time. The power management system will distribute part of the power input from the solar panel to the laptop and the mobile phone, and use the remaining power to charge the power station itself to maintain this state of charging and using.
2. However, the situation and reasons why charging and using at the same time is not recommended
1. Power management system limitations:
1. Some relatively low-end or simply designed portable power stations have limited power management system functions. They may not be able to handle the charging and discharging processes at the same time, and are not designed to charge and use at the same time. If used while charging, it may cause circuit disorder or even damage the power station.
2. Imbalance between charging power and power consumption:
1. If the charging power of the solar panel is too low and the power of the power device is too high, the power station will not be able to take into account both charging and power supply at the same time. For example, the charging power of the solar panel is only 10 watts, and the total power of the power devices connected at the same time reaches 50 watts. In this way, the power of the power station will drop rapidly and may be damaged due to excessive discharge. At the same time, this may also cause conflicts between the charging module of the solar panel and the discharging module of the power station, affecting the normal operation of the equipment.
3. Safety hazards:
1. During the process of charging and using, if the heat dissipation design of the equipment is not good, the heat generated by the simultaneous charging and discharging processes may accumulate, causing safety problems, such as battery overheating and explosion. This is especially likely to happen in some batteries with poor quality. Therefore, from a safety perspective, some power stations do not allow charging and use at the same time.
