What is the function of a 18650 li ion rechargeable battery and what are the misunderstandings about its use?
When the engine is starting, the 18650 li ion rechargeable battery supplies power to the starter and ignition system (gasoline engine). It can also convert the remaining electrical energy of the generator into chemical energy and store it. After shutting down the engine, you should try to avoid using electrical equipment for a long time. As follows Let’s give a detailed introduction to “the functions and usage misunderstandings of car batteries”.
1. The function of 18650 li ion rechargeable battery
1. When the engine is started, the battery supplies power to the starter and ignition system (gasoline engine).
2. When the engine is running at low speed, the battery supplies power to all electrical equipment and the generator excitation winding.
3. When the engine is running at medium or high speed, the battery converts the remaining electrical energy of the generator into chemical energy and stores it.
4. When the generator is overloaded, the battery assists the generator in supplying power to electrical equipment.
5. The battery is also equivalent to a large capacitor, which can absorb the instantaneous high voltage appearing in the circuit, protect electronic components, and also plays a very important role in maintaining voltage stability of the automotive electrical system. This function can only be guaranteed when the battery is in good working condition, which is easily overlooked by people.
2. Misunderstandings about using car batteries
1. Any operation of using electrical equipment in the car for a long time after turning off the engine will cause the battery to be over-discharged. For example, if you forget to turn off the lights after parking at night, the engine will not start the next day. A large part of the reason is due to the failure to turn off the car in time. Turning off the lights causes the battery to become depleted, at which point the battery's performance may have been significantly reduced.
2. After shutting down the engine, you should try to avoid using electrical equipment, such as audio, DVD, radio, lights, air conditioners, etc. for a long time. The time should not exceed 30 minutes. If you must use electrical equipment, it is best to start the engine with the generator. electrical energy.
3. When the engine is started, the battery will discharge with high current, but long-term high current discharge will greatly damage the battery. Each start time should not exceed 5 seconds. If it is started twice in a row, there should be an interval of 10 to 15 seconds.
4. Since the raw materials for manufacturing batteries cannot be 100% pure, there will always be impurities mixed in the middle, so the battery will inevitably have automatic discharge. The anti-theft alarm also needs electricity after turning off the engine. Therefore, for a long time When a vehicle is parked and not in use, the battery may be over-discharged. If the vehicle is parked for more than a week, please remove the negative connector of the battery and cut off the power supply.
5. Try to avoid using the 18650 li ion rechargeable battery with external high-power electrical equipment. Such equipment consumes a lot of power and may cause the battery to over-discharge. If it must be used, it is best to start the engine while using it and let the generator Powered by the battery.
6. Do not overcharge. If the voltage regulator of the car alternator is not set correctly, the output voltage of the alternator will be high. When the charging voltage exceeds the maximum limit voltage of the battery, overcharging may occur. At this time, If the fault is not checked and eliminated in time, the battery will overheat, causing abnormal consumption of electrolyte. Overcharging will accelerate the decomposition of active materials on the battery plates, causing the battery to fail.
