Emergency protection circuit device for battery vehicle charging

Abstract

The invention discloses an emergency protection circuit device for battery vehicle charging. The emergency protection circuit device comprises a vehicle body; an alarm lamp is embedded in the left endsurface of the vehicle body; a power supply cavity is formed in the vehicle body; a protection mechanism is arranged in the left end wall of the power supply cavity; a temperature measuring mechanismis arranged in the lower end wall of the power supply cavity; a heat dissipation cavity is formed in the right end wall of the power supply cavity; a heat dissipation mechanism is arranged in the heat dissipation cavity; the left side of the heat dissipation mechanism is connected with a transmission mechanism; a centrifugal mechanism is arranged on the transmission mechanism; a battery vehicle can be charged for a long time through the temperature measuring mechanism to dissipate heat of an internal storage battery, so that high-temperature aging of a circuit caused by a large amount of heatgenerated during internal quick charging is effectively avoided, and abnormal temperature firing, financial loss and larger fire disasters are avoided.

Description

technical field [0001] The invention relates to the technical field of emergency circuit protection devices, in particular to an emergency protection circuit device for battery car charging. Background technique [0002] At present, because the charging time of the battery car is generally relatively long, most people charge it at night while sleeping, and the long-term charging and the overload of the battery cause the temperature of the battery to rise easily, and the charging protection of the battery cannot be charged quickly. The large amount of heat generated during the operation can be effectively dissipated, which will easily cause the internal circuit and battery to accelerate aging and short circuit to cause abnormal temperature and fire. After the fire, it is easy to extend to the battery car and other objects close to the charger for combustion, and due to long-term charging Cause generally unattended when charging, thus seriously threaten people's life safety. ...

[0002] At present, because the charging time of the battery car is generally relatively long, most people charge it at night while sleeping, and the long-term charging and the overload of the battery cause the temperature of the battery to rise easily, and the charging protection of the battery cannot be charged quickly. The large amount of heat generated during the operation can be effectively dissipated, which will easily cause the internal circuit and battery to accelerate aging and short circuit to cause abnormal temperature and fire. After the fire, it is easy to extend to the battery car and other objects close to the charger for combustion, and due to long-term charging As a result, it is generally left unattended during charging, which seriously threatens people's lives.
