Rechargeable battery, charging method and unmanned plane

Abstract

The invention discloses a rechargeable battery which comprises a power input end, a battery unit, a switch circuit, a voltage collecting circuit and a microprocessor. The switch circuit comprises a control end, a voltage input end and a voltage output end. The voltage input end is electrically connected to the power input end, and the voltage output end is electrically connected to the battery unit. The voltage collecting circuit is electrically connected to the power input end and is used for acquiring the actual voltages of the power input end. The microcontroller comprises a first input end and a first output end, the first input end is electrically connected to the voltage collecting circuit, and the first output end is electrically connected to the control end. A voltage threshold value range is stored in the microcontroller, when the actual voltage value of the power input end is not within the voltage threshold value range, the microcontroller controls the switch circuit to be disconnected, and therefore the power input end can not charge the battery unit. The invention further relates to a charging method of the rechargeable battery and an unmanned plane.

Description

【Technical field】 [0001] The invention relates to a rechargeable battery, a charging method thereof, and an unmanned aerial vehicle using the rechargeable battery. 【Background technique】 [0002] In the field of model aircraft, most aircraft use batteries as the power source, and using batteries will naturally involve charging and discharging the batteries. Although existing rechargeable batteries have charge and discharge protection circuits, they are limited to protection against charge overcharge, discharge overdischarge, and overheating, but lack protection against excessive input charging voltage. Currently, chargers and batteries on the market use the same charging and discharging interface, but batteries with different voltages have different charging voltages. In some cases, batteries with different voltages may be confused. If you use an unmatched charger to charge the battery, when the charging voltage is higher than the maximum voltage that the battery can withst...

Problems solved by technology

Although existing rechargeable batteries have charge and discharge protection circuits, they are only limited to protection against charge overshoot, discharge overdischarge, and overheating, but lack protection against excessive input charging voltage.

Currently, chargers and batteries on the market use the same charging and discharging interface, but batteries with different voltages have different charging voltages. In some cases, batteries with different voltages may be confused.

If you use an unmatched charger to charge the battery, when the charging voltage is higher than the maximum voltage that the battery can withstand, there will be a danger of battery damage or even burning and explosion
