Title: TIME-SHARING COMMUNICATION METHOD AND SYSTEM FOR ALTERNATING CURRENT CHARGING APPARATUS AND OBJECT TO BE CHARGED
Abstract:
A time-sharing communication method and system for an alternating current (AC) charging apparatus and an object to be charged, the communication system comprising first switches (K1, K2) and a third switch (K5) arranged on an AC charging pile which are connected to an AC power source (11) and a pile communication unit (12), respectively, and second switches (K3, K4) and a fourth switch (K6) arranged on an electric vehicle which are connected to a vehicle-mounted charger (21) and a vehicle communication unit (22), respectively; when the AC charging pile and the electric vehicle need to communicate, the charging connection may be switched to a communication connection by merely turning off the first switches (K1, K2) and the second switches (K3, K4) and turning on the third switch (K5) and the fourth switch (K6), which solves the problem in existing technology of communications between an AC charging pile and an electric vehicle in a wireless mode being easily influenced by environment such that the data transmission is not stable enough and data may be easily stolen.
