Abstract

The invention discloses a battery overcharging prevention device for a new energy automobile. The battery overcharging prevention device comprises a charging pile, wherein a sampling circuit is arranged inside the charging pile; a switch circuit is connected with a charging control circuit through a conducting wire; the charging control circuit is connected with a battery charging voltage detection circuit through a conducting wire. The device has the advantages that a battery charging voltage detection circuit used for collection is arranged; when the battery charging is completed, the battery charging voltage detection circuit can transmit the collected signals to a signal receiver; the signal receiver can transmit the signal to a PLC; the PLC can control an electric push rod to contract, so that a charging plug can be pulled out from a charging hole; the battery is not charged; the battery is subjected to overcharging protection; meanwhile, the switch circuit is installed, the PLC can control the switch circuit to break; the power failure of the circuit is realized; the battery charging is completed. The battery overcharging protection structure with duplex effect ensures the use stability of the battery overcharging device.

Description

technical field [0001] The invention relates to the technical field of overcharge protection devices, in particular to a battery overcharge prevention device for new energy vehicles. Background technique [0002] New energy vehicles include pure electric vehicles, extended-range electric vehicles, hybrid vehicles, fuel cell electric vehicles, hydrogen engine vehicles, and other new energy vehicles. A pure electric vehicle is a vehicle that uses a single battery as the energy storage power source. It uses the battery as the energy storage power source, and supplies electric energy to the motor through the battery to drive the motor to run, thereby driving the car. Hybrid Electric Vehicle A hybrid electric vehicle refers to a vehicle whose drive system is composed of two or more single drive systems that can operate simultaneously. . Due to the different components, layout and control strategies, there are many forms of hybrid electric vehicles. [0003] However, the existi...
