When an electric vehicle needs a new battery, many owners choose to buy one and assemble and fit it themselves at home. But if an electric vehicle battery is not installed correctly, not only is its quality affected, it can also pose a safety hazard. Here we first introduce how to assemble an electric vehicle battery:

1. Inspection

While removing the battery, check the quality of all wiring, and check whether the fuse holder, charging socket, and battery lead-out wires make normal, reliable contact, then tighten all connectors. Replace anything that needs replacing, focusing on its reliability, and replace any unreliable part.

2. Installation

Install the battery according to the instructions in the packaging box. In fact, most cells inside a battery box are connected in series. Use copper wire of no less than 1 mm squared to solder each cell in series with a soldering iron, leaving two output terminals, positive and negative, which are welded to the two contacts of the output socket. Be careful not to reverse them; they must match the polarity of the charger, or the consequences will be serious.

3. Testing

After installation, use a multimeter to measure the voltage at the battery output terminals. The actual voltage should be slightly higher than the rated voltage by 2-5 V, and only after it is normal should the battery be put into regular use.

With these three steps, you can basically learn how to assemble an electric vehicle battery. Of course, we still recommend going to a professional battery assembly shop. With incorrect assembly and long-term vibration and wear, the battery life will also be shortened, so it is important to learn how to assemble an electric vehicle battery correctly.
