4results about How to "Prevent overdischarge" patented technology

This invention provides an extreme energy-saving range control method and system for new energy vehicles, comprising: acquiring vehicle operating status information and adaptively activating an energy-saving range mode based on the operating status information; dividing the vehicle's battery rated capacity into a normal driving stage range and an emergency driving stage range according to a ratio based on the activation result, and adaptively adjusting the vehicle's power output and accessory energy consumption based on the vehicle's real-time battery level in the normal driving stage range; adjusting the vehicle's standard operating procedures when the vehicle's battery level enters the emergency driving stage range, and prohibiting the vehicle from driving when the battery level reaches 0. This method effectively extends the vehicle's driving range, avoids battery over-discharge, and better meets user needs and vehicle protection requirements.

This application discloses an auxiliary power supply module and a power distribution terminal, belonging to the field of power supply. The auxiliary power supply module includes a charging circuit, an energy storage unit, a power failure detection delay circuit, a boost circuit, and a power output terminal. The charging circuit is connected to the energy storage unit and is used to charge the energy storage unit using the main power supply voltage when the main power supply voltage is normal. The power failure detection delay circuit is connected to both the charging circuit and the boost circuit and is used to output a working voltage to the boost circuit when the main power supply voltage is less than a first target voltage for a target duration. The energy storage unit is connected to the boost circuit and is used to output a stored energy voltage to the boost circuit. The boost circuit is connected to the power output terminal and is used to supply power at the working voltage, converting the stored energy voltage into a supply voltage and providing it to the power output terminal. The supply voltage is used to power the power distribution terminal. This application can improve the service life of the auxiliary power supply module and improve the stability of power supply.

This utility model relates to the field of microphone technology, specifically to an intelligent wireless microphone, comprising a battery module, a charging module, a control module, a first comparison module, and a second comparison module. The battery module includes a lithium battery, which is connected to the control module for power supply via a voltage regulator module. The charging module charges the lithium battery. When the lithium battery voltage is lower than a first voltage, the first comparison module outputs an alert signal to the alert module. When the lithium battery voltage is lower than a second voltage, the second comparison module outputs a power-off signal to the voltage regulator module, causing the control module to lose power. The battery module also includes a battery protection chip that disconnects the lithium battery's discharge circuit when the lithium battery voltage is lower than a third voltage, where the first voltage is greater than the second voltage, and the second voltage is greater than the third voltage. This utility model provides an intelligent wireless microphone that is rechargeable, highly intelligent, provides low battery alerts, prioritizes power supply, and prevents over-discharge.
