Electric vehicle lithium battery packaging tutorial and matters needing attention

Electric vehicle lithium battery packaging tutorial 1. Prepare materials, including stainless steel battery box, 60V24AH lithium battery for electric vehicle assembly, lithium battery must use electric vehicle power lithium ion battery. 2. Put 20 lithium batteries in a string, a total of 8 strings. 3. Connect 8 strings of lithium batteries in parallel and insulate them with separators and tape. 4. The tape is fixed, and the protective wire is welded in series. 5. Wrap the string-welded lithium battery pack with heat shrinkable film to insulate, and connect it to the protection board to insulate and be wary of short circuits. 6. The short circuit of the lithium battery is very harmful. After the heat shrinkable film wraps the lithium battery, the electric vehicle lithium battery packaging is completed, and it can be placed in the electric vehicle. Precautions for electric vehicle lithium battery packaging Step 1: Check the quality of all connections during the process of disassembling the battery. At the same time, check whether the fuse holder, charging socket, and the lead wire of the electric vehicle lithium battery are normal and reliable, and tighten all Connecting pieces. The ones that need to be replaced should be replaced, and the reliability should be focused on, and those that are unreliable should be replaced. Step 2: Install the lithium battery of the electric vehicle according to the instructions in the battery assembly box. In fact, most of the batteries inside the battery box are connected in series. Use a copper wire of no less than one square to connect each battery in series with a soldering iron, and finally there are two output terminals positive and negative. , Welded on the two pieces of the output socket, be careful not to connect them backwards, and must correspond to the positive and negative poles on the charger. Otherwise, the result will be serious. Step 3: After installing the lithium battery pack for electric vehicles, use a multimeter to measure the battery output port voltage. The actual battery voltage should be 2~5V higher than the standard voltage. It can be put into normal operation after it is normal.
