The invention relates to an outfield special constant-current power compensating device for a model airplane battery, belonging to the technical field of electronics. Although chargers used for charging batteries are diverse on the market, a charging device really suitable for the model airplane battery in an outfield is difficult to get. Rechargeable batteries are usually fully charged overnight indoors by model airplane amateurs or players and taken outside for activities or competitions next day; however, the rechargeable batteries stand for a whole night, the peak voltage of the rechargeable batteries is greatly decreased due to the factors of self discharge and the like, and the energy with large fulmination is lost along with the decreasing of the peak voltage. Aiming at the phenomenon that the rechargeable batteries have a self discharge characteristic, the constant-current powder compensating device for the model airplane battery used in the outfield is invented and is particularly suitable for the electric speed competition, the lastingness, the free fly and the tethering of the model airplane and other activities. If the power compensating device can be used for the outfield power compensation of a model airplane dynamic battery set before the competition, the phenomenon that the peak voltage of the rechargeable batteries is greatly decreased can be effectively made up or improved so that preemptive opportunities can be quickly obtained in motions once the model airplane works.
Description
technical field [0001] The invention belongs to the field of electronic technology, and relates to a special constant-current power supply device for the outfield of aeromodelling batteries. Background technique [0002] At present, there are many types of chargers for recharging batteries on the market. The charging technologies used in chargers include variable current and constant voltage, variable voltage and variable current, pulse type, constant current and constant voltage, etc., but all charging devices Once the rechargeable battery is fully charged and disconnected from the charging device, the voltage of the rechargeable battery will drop to a certain extent compared with the peak voltage during online charging. The main reason is the negative effect caused by the self-discharge phenomenon of the rechargeable battery. The design and use of general charging devices generally cannot face the existence of this problem. The peak voltage (power) of the rechargeable batt...
