Narrative:
After landing; we taxied and held short on taxiway south. Operations were backed up on the taxiways and ramp due to weather complications and traffic congestion. We received a master warning and batt 1 overtemp EICAS warning. We confirmed the battery to be overtemping (70 C at this time) and completed the immediate action items and I instructed the first officer (first officer) to run the battery overtemp QRH. As he retrieved that; I informed ATC that we may need assistance and noticed the temperature to continue increasing. After the immediate action items and QRH were completed; the temperature continued to runaway so we asked for priority handling and had airport rescue and firefighting (arff) dispatched should the battery ignite or a fire situation start. We were given said priority handling to return to the gate promptly and arff met us at the gate. ATC relayed our situation to the company and I briefed the flight attendant using the test items. We were able to deplane expeditiously rather than evacuate; and arff confirmed there was no fire but the battery temperature was extremely hot. The last temperature we saw on the EICAS was 80 C; but a ground person or firefighter (can't remember who) told us after the event it had reached 100. The plane was written up after giving dispatch the information necessary for their report.

Title: EMB-145 Captain reported a battery overheat during taxi to the gate.
Narrative: After landing; we taxied and held short on taxiway S. Operations were backed up on the taxiways and ramp due to weather complications and traffic congestion. We received a Master Warning and BATT 1 OVERTEMP EICAS Warning. We confirmed the battery to be overtemping (70 C at this time) and completed the immediate action items and I instructed the First Officer (FO) to run the Battery Overtemp QRH. As he retrieved that; I informed ATC that we may need assistance and noticed the temperature to continue increasing. After the Immediate Action Items and QRH were completed; the temperature continued to runaway so we asked for priority handling and had Airport Rescue and Firefighting (ARFF) dispatched should the battery ignite or a fire situation start. We were given said priority handling to return to the gate promptly and ARFF met us at the gate. ATC relayed our situation to the company and I briefed the flight attendant using the TEST items. We were able to deplane expeditiously rather than evacuate; and ARFF confirmed there was no fire but the Battery temperature was extremely hot. The last temperature we saw on the EICAS was 80 C; but a ground person or firefighter (can't remember who) told us after the event it had reached 100. The plane was written up after giving Dispatch the information necessary for their report.
