Problems solved by technology
The plug-in charging method has the following defects: 1. The initial investment cost of the battery is relatively large, which hinders the popularization of electric vehicles to a certain extent; 2. The charging time is too long, at least 2 to 4 hours, which is comparable to the refueling of ordinary cars Compared with electric vehicles, it takes too long to recharge energy, which is very inconvenient and far from meeting people's needs
The fast charging mode will cause greater damage to the battery, resulting in shortened battery life

The invention relates to a battery replacement method for an electric vehicle. The method includes: after lifting the power battery lifting platform to a preset position, using a drive motor to drive the locking and unlocking sleeve to rotate so that the locking and unlocking sleeve faces toward the The tightening direction of the unlocking nut is used for the first cap recognition; the driving torque of the drive motor is monitored to determine whether the first cap recognition is successful; if the first cap recognition is successful, proceed in the direction of loosening the unlock nut. Unlocking for the first time; monitoring the driving torque and the number of rotations of the drive motor to determine whether the first unlocking is successful; if the first unlocking is successful, lowering the power battery lifting platform to determine whether the power battery is unloaded to The power battery lifting platform; if the power battery is unloaded to the power battery lifting platform, it is confirmed that the unlocking is completed. The implementation of the present invention can improve the success rate of a single battery replacement, improve user experience, and reduce maintenance operations.
Description
technical field [0001] The invention relates to the field of battery swap stations, in particular to a battery swap method for electric vehicles. Background technique [0002] 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, among which there are two modes of plug-in charging: slow charging and fast charging. The plug-in charging method has the following defects: 1. The initial investment cost of the battery is relatively large, which hinders the popularization of electric vehicles to a certain extent; 2. The charging time is too long, at least 2 to 4 hours, which is comparable to the refueling of ordinary cars Compared with electric vehicles, it takes too long to recharge energy, which is very inconvenient and far from meeting people's needs. The fast charging mode will cause greater damage to the battery, resulting in shortened battery life. [0003] Ado...
