Kp & Ki

Can some one please explain the relationship between Kp & Ki in the controller settings & how do the different settings make the controller behave.
For example (for all examples use a 144V pack, the same motor & a 100Ah LiFePo battery pack):

If Kp is 2, what is the difference between having Ki at 20 or having Ki at 100.

What would the likely results be with the following different settings:
Kp 2 Ki 20
Kp 6 Ki 50
Kp 1 Ki 160

The wiki description does not really explain how the 2 interact together & what effect on the controller the differing settings actually make.
