Currently, that's what the 50mv shunt is for. It'd need amplification though. I suspect a hall effect sensor would work too.

I'm just thinking out loud now...
Perhaps an even better place to monitor current would be on the AC line. I think AC hall effect current sensors are pretty cheap and would allow you to set and max out the power source throughout the charge cycle. Otherwise, if you hold the battery current constant, your power draw will increase a little as the voltage rises, potentially tripping the breaker partway through charging (and likely unknowingly in the middle of the night).
