Based on the joih hardware solution + transportation energy supply big data, the regional electric vehicle and charging pile energy supply solution forms the 3S charging principle of charging interconnection, resource sharing and safe charging, and realizes the resource integration under the Internet of things mode through the combination of technology and operation.

The solution of fast charging and slow charging of electric vehicles by using joih technology has passed the local standards of Henan Province, and the local pilot is under construction. Joih grabs the charging data of fast charging and slow charging of electric vehicles, which is used to guarantee the problems in the process of overcharging and charging, and put an end to potential safety hazards
