The invention discloses a charging terminal charging output power control method and device, equipment and a storage medium. The method comprises the following steps: when a charging request of a charging terminal is received, acquiring a duty ratio value range of a controllable rectifier of a secondary circuit of a charging network equivalent circuit; determining whether an intersection exists between the duty ratio value range and a preset duty ratio value range or not; when the duty ratio value range does not intersect with a preset duty ratio value range, the output power is reduced according to the corresponding relation between the output power and the preset duty ratio value range, and target output power is obtained; acquiring an electrical stress parameter of the charging terminal during charging; the target output power is controlled based on the corresponding relation between the output power and the preset duty ratio value range and the electrical stress parameter, the output power is made to meet the electrical stress parameter requirement through power transmission detection, the safety and reliability of wireless charging are guaranteed, and the wireless charging efficiency is improved. And the problem of unstable charging in a high-voltage and high-power output state is avoided.

    本发明公开了一种充电终端充电输出功率控制方法、装置、设备及存储介质。本发明在接收到充电终端的充电请求时,获取充电网络等效电路的副边电路的可控整流器的占空比取值范围;确定占空比取值范围与预设占空比取值范围是否有交集;在占空比取值范围与预设占空比取值范围无交集时,根据输出功率与预设占空比取值范围的对应关系,降低输出功率,得到目标输出功率;获取充电终端充电时的电气应力参数;基于输出功率与预设占空比取值范围的对应关系以及所述电气应力参数对所述目标输出功率进行控制,通过在功率传输检测,使输出功率满足电气应力参数要求,保证无线充电的安全性和可靠性,避免了高压和大功率输出状态下充电不稳定的问题。
