Will the battery of an electric vehicle burn out if the positive and negative terminals are connected? Here are the relevant explanations: 1. Reason for damage: If the positive and negative terminals of the battery are directly connected, it is equivalent to connecting the battery to a very short wire with no resistance in between, thus generating a large current. Since the battery's internal power source inherently contains resistance, a large current flow will produce significant heat, damaging the battery. 2. Working principle: It converts chemical energy into electrical energy. The battery commonly referred to is a lead-acid battery, which mainly uses lead and its oxides as electrodes and a sulfuric acid solution as the electrolyte. There are lead-acid batteries, nickel-iron batteries, and nickel-cadmium batteries, among others. The positive electrode of a lead-acid battery is lead dioxide, the negative electrode is lead, and the electrolyte is a dilute sulfuric acid solution.
