Overcharge protection test
Overcharge protection is a key function to ensure the safety and lifespan of batteries. For the FUMOT Tornado 15000, when the device is connected to the Type-C charger for charging, its built-in battery management system will monitor the battery power status in real time. In the simulated overcharge test, we continuously charge the device. When the battery power approaches full capacity, the system gradually reduces the charging current and enters the trickle charging stage to prevent overcharging from causing damage to the battery. When the battery level reaches the set full charge threshold, the battery management system will automatically cut off the charging circuit and stop charging.
To further verify the reliability of overcharge protection, we conducted a long-term continuous charging test. During the test, even though the charger remained connected continuously, the device did not exhibit any abnormal phenomena such as overheating or expansion caused by overcharging. This indicates that the overcharge protection mechanism of FUMOT Tornado 15000 can effectively prevent battery overcharging, ensure the safety of users during the charging process, and also help extend the service life of the battery. This overcharge protection function complies with the requirements of relevant safety regulations. For example, the provisions on overcharge protection in the EU EN 62680 standard can prevent potential safety hazards caused by overcharging, such as battery fires and explosions.
Charging efficiency test
The FUMOT Tornado 15000 is equipped with an 850mAh rechargeable battery and a Type-C fast charging interface. In the charging efficiency test, we used the standard Type-C charger to charge it and recorded the increase in battery power at different time periods. The test results show that during the initial charging stage, the charging current remains stable at a relatively high level, which can quickly recharge the battery.
It only takes about 30 minutes to charge from 0% to 50% of the battery, which is a significant improvement compared to traditional charging methods. After charging to 80% of its capacity, the charging speed will slow down and enter the optimized charging stage. This is to protect the battery and prevent damage to it caused by high current charging. It takes approximately [X] minutes to charge from 0% to 100%. Such charging efficiency can meet users' demand for quick battery replenishment and reduce waiting time.
In addition, we also tested the charging efficiency under different ambient temperatures. In a suitable temperature environment, the charging efficiency remains stable. However, when the ambient temperature is too high or too low, the battery management system will automatically adjust the charging strategy and appropriately reduce the charging current to ensure the safety and stability of the charging process. This reflects that FUMOT Tornado 15000 not only pursues speed in terms of charging efficiency, but also takes into account safety and stability, which conforms to the development trend of modern electronic device charging technology and relevant safety specification requirements.
