Abstract

The invention discloses an unmanned aerial vehicle, a battery module and a charge-discharge control method. The battery module comprises a battery body, an outer case, a heat conducting assembly, a first heating piece, a second heating piece, a temperature sensor and a control assembly, wherein the battery body is arranged in the outer case; the heat conducting assembly is connected between the outer case and the battery body in a heat conducting manner; the first heating piece is used for heating the battery body; the second heating piece is used for heating the heat conducting assembly; the temperature sensor is used for detecting temperature of the battery body and producing a temperature signal according to the detected temperature of the battery body; the control assembly is electrically connected with the first heating piece, the second heating piece and the temperature sensor and used for receiving the temperature signal and controlling the first heating piece and the second heating piece according to the temperature signal. According to the battery module, normal charge and discharge of the battery module can be guaranteed, charge-discharge performance of the battery module can be improved, and heat produced by the battery body can be dissipated effectively and rapidly in time.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to an unmanned aerial vehicle, a battery module and a charging and discharging control method. Background technique [0002] In recent years, driven by various factors, the power battery module has been widely used in various fields due to its high energy density and high-rate partial charge cycle, such as electric vehicles, wireless Man-machine and other industries. However, only when the power battery module is within a suitable temperature range can its performance and service life be well maintained. [0003] Usually, the impact of temperature on the battery is manifested in two aspects; in low temperature environments, such as winter, the battery capacity is reduced, and the temperature in the battery is too low, which is not conducive to the electrochemical reaction of the battery. The chemical reaction is slow and energy is easily lost, which cannot meet the requirements o...
