    Abstract: An ultrasonic battery-mounting device, having a battery holder, a base, shock-absorbing parts, an ultrasonic vibrating motor installed at a bottom surface of the battery holder to achieve high frequency ultrasonic vibration of the battery holder, and a battery fixture part provided on the battery holder. The battery holder is provided on the base, and the shock-absorbing parts are installed between the battery holder and the base to reduce vibrational transfer from the battery holder to the base. The ultrasonic vibrating motor produces ultrasonic vibration in high frequency, causing battery fluid or particles in the battery to move in high frequency to reduce the problems of internal crystallization and blockage due the formed crystals, or poor flow of electrons due to low external temperature, thereby maintaining the battery in a well-functioning condition without changing the internal structure of the battery.

  • Patent number: 12136825
    Abstract: An in-flight contact charging system includes a charging contact, a power receiver, and a recharging controller connected to the charging contact. The charging contact is mounted on a support. The power receiver is mounted on an aerial vehicle containing an electrical load. The power receiver connects to the electrical load. The recharging controller can detect contact between the charging contact and the power receiver; transmit electricity to the charging contact; detect a spike in battery impedance; and discontinue transmission of electricity to the charging contact. The system enables a drone to rapidly recharge its battery while in flight by making brief contact between the charging contact and the power receiver. This system keeps the drone airborne, does not waste energy, and is comparatively cheap to build and maintain.
