In daily use of electric vehicles, we often find that the battery doesn't last long and the range is limited. When repairing the vehicle, we emphasize this issue to the mechanic. Through the mechanic's explanation, we learn that the battery's short lifespan isn't solely due to lower winter temperatures; another reason is a minor problem that occurred during battery replacement or installation.
Don't underestimate these seemingly minor details; they often have a significant impact on battery life. DIY installations are convenient and less prone to problems, but electric vehicle batteries are unlike other products; DIY installation can easily lead to human-caused damage. Therefore, if you don't want to hire a mechanic to install the battery, learn some electric vehicle battery installation techniques from Teacher Xiaowei to make your electric vehicle battery last longer.
First, you need to prepare the necessary tools: soldering iron, solder, battery connection cable, and professional screwdriver.
Then, there are the various installation techniques:
1. Choose high-quality batteries from reputable brands with warranties. Batteries that have undergone professional testing are more reliable. Never use refurbished batteries. Want a recommendation from Teacher Wei? You know what I mean...
2. Before installation, check the battery for damage or leakage, and clean the battery surface with a dry cloth. If any problems such as damage or leakage are found in the battery casing, the battery should be replaced immediately.
3. The battery should be installed upright, not upside down. It should also be protected against shock and pressure, and be securely installed. During use, it should be protected from impact, friction, and water ingress.
4. The battery box where the battery is installed must have a vent hole for ventilation, and it must not be blocked to prevent the gas generated by the battery from accumulating inside the battery box, so as to ensure the safe use of the battery.
When installing the battery, ensure that the connecting wires are secure and that the wires do not press against the battery. After installation, the battery should not be loose, and incompatible battery cases should not be used.
In addition to installation tips, Teacher Wei would also like to add a few points about usage precautions:
1. Do not recharge the battery after it is completely depleted, and do not use the battery's "recovery voltage" to force driving, as this can shorten battery life due to "over-discharge";
2. Batteries must not be stored for extended periods while in a discharged state;
3. If the battery has been continuously charged for more than 10 hours and the charger indicator light does not change, and the battery becomes hot, charging should be stopped immediately and the battery should be handed over to the after-sales service center for handling. It is strictly forbidden to continue charging if the charger indicator light does not change.
4. Batteries of different models, brands, and ages should not be mixed;
5. Keep the battery away from fire and heat sources. In hot seasons, it is strictly forbidden to expose it to direct sunlight. Avoid violent vibrations, collisions, and short circuits between the positive and negative terminals.
