A charging connection control system and a swap station

Abstract

The invention provides a charging connection control system, including a controller, a battery pack management system and a charging circuit, the charging circuit is connected to the controller and the battery pack management system, the battery pack management system includes a battery pack and a battery pack controller; the charging circuit includes a charging The connecting device and the driving device, the driving device is electrically connected to the controller, the driving device drives the charging connecting device to switch between the first contact and the second contact, when the charging connecting device is connected to the first contact, The charging circuit is turned on; when the charging connection device is in contact with the second contact, the charging circuit is disconnected; the charging connection control system provided by the present invention can simultaneously communicate with the battery pack and the battery pack controller , or by disconnecting the charging connection with the battery pack and the electrical connection with the battery pack controller to simplify the control logic and save control resources while overcoming the hysteresis problem caused by connecting the battery pack first and then connecting the battery pack controller in the prior art.

Description

technical field [0001] The invention relates to the field of charging control, in particular to a charging connection control system and a power exchange station. Background technique [0002] The problems of small battery storage energy and unsatisfactory mileage after one charge have always restricted the development of electric vehicles. At present, the power supply methods of electric vehicle power batteries are generally divided into two methods: plug-in charging with the car and battery replacement. The plug-in charging method has the following defects: 1. The initial investment cost of the charging pile is relatively large, which hinders the charging to a certain extent. 2. The charging time is too long, at least 2 to 4 hours. Compared with the refueling of ordinary cars, the time it takes for electric vehicles to replenish energy is too long; 3. The fast charging mode in plug-in charging is easy to use. The battery causes a lot of damage, resulting in a shortened ba...

[0002] The problem of small battery storage energy and unsatisfactory mileage after one charge has always restricted the development of electric vehicles

At present, the power supply methods of electric vehicle power batteries are generally divided into two methods: plug-in charging with the car and battery replacement. The plug-in charging method has the following defects: 1. The initial investment cost of the charging pile is relatively large, which hinders the charging to a certain extent. 2. The charging time is too long, at least 2 to 4 hours. Compared with the refueling of ordinary cars, the time it takes for electric vehicles to replenish energy is too long; 3. The fast charging mode in plug-in charging is easy to use. The battery causes a lot of damage, resulting in shortened battery life

When supplying power to the deficient battery in the battery compartment, it is often necessary to couple and connect the charging connector to the battery pack first, and then connect to the battery pack controller. After the battery pack controller collects and analyzes the in-place information, it controls the battery The charging of the bag, the control logic is cumbersome, and there is a problem of charging lag

In addition, because most of the charging connectors are plugged and unplugged, not only there are certain safety hazards, but also the electrical performance of the charging plug will be reduced.
