Abstract

The invention discloses an electric-vehicle battery lock and belongs to protective articles of the electric vehicles. A controller of the electric-vehicle battery lock is disposed in the internal space between a storage battery shell and a sealing cover, the core part of the controller is a mini-type RFID (radio frequency identification) reader which is connected with one contactor, current contacts of the contactor are in tandem connection in battery packs, and the RFID reader and the contactor are powered by the battery packs which are not controlled in the storage battery; the contactor is started when the RFID reader detects an RFID chip in a digital key, the storage battery provides power supply normally, and when RFID chip signals cannot be detected within preset time, the power supply circuit is disconnected from the interior of the storage battery; when a driver carrying a digital key is far away from an electric vehicle, the storage battery of the electric vehicle can automatically stop power supply; at this time, a thief cannot ride off the electric vehicle even a common anti-theft device is turned open, and the storage battery cannot be replaced within a short time. The electric-vehicle battery lock is concealed in structure, convenient and practical and obvious in effect.

Example Embodiment

[0008] As attached figure 1 As shown, the controller of the battery lock of the present electric vehicle is installed in the internal space between the battery housing 2 and the sealing cover 1, which is consistent with an ordinary battery from the outside, and has good concealment. Even if the thief knows that the battery cannot supply power, it cannot be replaced or repaired in a short time.
[0009] The core component of the controller is a miniature RFID reader 5, which is connected to a contactor 6, and the current contacts of the contactor 6 are connected in series in the battery pack. This is the simplest way to disconnect the power supply, but because it is arranged in the sealing cover 1, it has a strong anti-theft performance.
[0010] The RFID reader 5 and the contactor 6 are powered by an uncontrolled battery pack in the storage battery. Usually there are more than 6 single batteries in the battery. Controlling any one can achieve the purpose of disconnecting the power supply circuit. There is no voltage on the positive electrode 3 and negative electrode 4 of the battery, and the uncontrolled battery pack can always affect the RFID reader 5. And the contactor 6 normally supplies power.
[0011] When the RFID reader 5 detects the RFID chip in the digital key, the contactor 6 is activated, and the battery supplies power normally. When the RFID chip signal is not detected within a predetermined time, the power supply circuit is disconnected from the battery. The predetermined time range is 1-5 minutes.
[0012] Both the RFID reader 5 and the contactor 6 are commercially available products, and their working principles are not described here.
