Control device and method of pulse-and-level-compatible electronic lock

Abstract

The invention discloses a control device and method of a pulse-and-level-compatible electronic lock. The control device comprises an energy storage capacitor C1, a first switch device K1, a second switch device K2 and a power source provided with a first power supplying contact and a second power supplying contact; the first switch device K1 is connected with the grounded end of the electronic lock and used for selectively switching on one end of the energy storage capacitor C1 or the first power supplying contact; the second switch device K2 is connected with the other end of the electronic lock and used for selectively switching the other end of the energy storage capacitor C1 or the second power supplying contact; both the first switch device K1 and the second switch device K2 can switch on the energy storage capacitor C1, and are in the initial state, and the electronic lock is in the unlocked state. The control method includes the steps that the read state of the electronic lock is compared, and the type of the electronic lock is judged based on the comparing result; based on the judged type of the electronic lock, the corresponding electronic lock is controlled to be locked or unlocked.

Description

technical field [0001] The invention relates to the fields of energy and electric vehicles, in particular to a control device and a control method compatible with pulse and level electronic locks. Background technique [0002] With the popularity of electric vehicles, charging safety, especially the safety of DC charging, has become the focus of attention. The national standard has clearly stipulated that for charging equipment with a charging current greater than 16A, there must be a locking device. [0003] At present, there are mainly two types of charging gun head locking devices, one is a level type (single-phase magnetic holding electronic lock) electronic lock, and the other is a pulse type (two-phase magnetic holding electronic lock) electronic lock. Due to the current transformation of old stations or the entry of new national standards, the charging system cannot be compatible with level and pulse electronic locks, resulting in the phenomenon that the electronic lo...

AI Technical Summary

Problems solved by technology

Due to the current transformation of old stations or the entry of new national standards, the charging system cannot be compatible with level and pulse electronic locks, resulting in the phenomenon that the electronic lock cannot be locked during charging or the electronic lock cannot be unlocked in time after charging.
