Description

In-bin battery on-site detection device in power change cabinet

Technical Field

The utility model relates to a battery test technical field, more specifically say, relate to a battery detection device on throne in storehouse in the cabinet trades electricity.

Background

Secondly, a three-wheeled electric vehicle charging and changing cabinet (hereinafter, called as a changing cabinet) is a sharing system for a power supply vehicle rider with great civil demands to directly replace a full-charge battery with an under-voltage battery in the current market. The system has the function of simultaneously charging a plurality of high-capacity batteries, each battery is generally placed in an independent battery bin, each bin body is provided with a bin door, and the bin door is provided with an electronic lock, so that the batteries are prevented from being stolen. The battery replacing cabinet system is an unattended automatic system, when the system cannot correctly judge whether batteries are placed in a battery compartment, a series of wrong operations can be caused, and even a compartment door with the batteries is opened as an empty compartment, so that the batteries are lost, and the consequences are very serious.

Currently, there are three in-place detection schemes commonly used in the market: firstly, whether a communication message exists between the battery and the cabinet control system is judged, such as a serial port signal, a CAN port signal and the like. And in the second type, a travel switch is arranged in the bin, and the judgment is carried out by extruding the travel switch through placing a battery in the bin. The travel switch is one of position switches, and is a common low-current master control electrical appliance. The contact of the mechanical motion part is operated by the collision to realize the connection or disconnection of the control circuit, thereby achieving a certain control purpose. Thirdly, a photoelectric on-site switch is arranged in the bin, and whether the battery in the bin exists is detected through the photoelectric on-site switch, for example, the mounting mode shown in the figure (1) is one of the mounting modes. When objects such as a battery and the like approach the photoelectric on-site switch, the existence of the objects can be detected through infrared rays.

For the first, when the battery cannot communicate normally, the battery cannot be detected, and the battery is often lost. For the second kind, an additional device is needed, the cost is increased, and the 'travel switch' is not in place due to the deviation of the placement position of the battery, so that the battery is easily forged by a fake object, and the misjudgment is caused. For the third kind, additional devices are required, which increases the cost, and the "photoelectric on-site switch" usually has a short service life, and is also easy to counterfeit the battery by a fake object, resulting in misjudgment.
