+- The goal for Open Charge Point Protocol (OCPP) is to offer a uniform solution
+ for the method of communication between charge point and central system.
+  With this protocol it is possible to connect any central system with any
+   charge point, regardless of the vendor. A uniform standard prevents
+    all kinds of coordination problems and  is therefore an advantage
+     for the whole electric vehicle market.
