+TODOs left for this implementation
+- The battery has 3 CAN ports. One of them is responsible for the 7E4 polls, the other for the 7E7 polls
+- Current implementation only seems to get the 7E7 polls working.
+- Could on of the CAN channels be GMLAN?
+
+- The values missing for a working implementation is:
+- SOC% missing! This is absolutely mandatory to fix before starting to use this!
+- Capacity (kWh) (can be estimated)
+- Charge max power (can be estimated)
+- Discharge max power (can be estimated)
+- SOH% (low prio))
