Apparatus for preventing overcharge of battery in eco-vehicle

An apparatus for preventing an overcharge of a battery in an eco-vehicle, the apparatus comprising:

• a detector detecting the overcharge of the battery;
• and
• a signal processor controlling a high voltage relay according to an output signal output from the detector to block a charge of the battery,
• wherein the signal processor includes a sub signal processor outputting an output signal according to an overcharge detection signal from the detector, a plurality of logical elements, and a controller operating an overcharge protection function of the battery when the vehicle starts, and
• wherein the plurality of logical elements performs a logic operation using output signals output from the sub signal processor and the controller, and the signal processor controls the high voltage relay according to a result of the logic operation.
