Almost certainly it is the voltage regulator on the alternator. An easy way to check is measure the battery voltage while the engine is running it should read around 13.5-14.5v. If it is much higher then the voltage regulator has failed.

Dont drive your car with high voltage, the engine management system and speedometer can fail.

It is a very simple (2hour) job to replace it
