3.7 volt 18650 lithium battery

　　What are the advantages of energy storage batteries and what are the precautions?

　　The raw materials of energy storage batteries are easy to obtain and the prices are affordable. Used batteries are easy to recycle, which is conducive to protecting the environment. They have a long service life and can be deeply discharged. When outside the forest, be careful to stay away from flammable and explosive items, fire sources and other materials. Hazardous chemicals. Next, I will introduce the detailed content to you.

　　1. Advantages of energy storage batteries

　　1. The raw materials are easy to obtain and the price is relatively low.

　　2. Good high-rate discharge performance.

　　3. It has good temperature performance and can work in the environment of -40~+60℃.

　　4. Suitable for float charging, with long service life and no memory effect.

　　5. Used batteries are easy to recycle, which is beneficial to environmental protection.

　　6. Safe and capable of deep discharge.

　　7. Large scale, no limit on tank size.

　　8. Has a high charge and discharge rate.

　　9. Long life and high reliability.

　　2. Precautions when using energy storage batteries

　　1. The charging time of the energy storage battery becomes longer at low temperatures, which is a normal phenomenon. At low temperatures, the BMS will engage the heating relay, request the heating voltage and current from the OBC through CAN, and then charge while heating (or first heat to a certain level). After the temperature is reached, it enters the state of charging while heating.

　　2. When the vehicle is parked and charged in a low-temperature environment with high battery capacity, due to the chemical characteristics of the battery, the SOC may jump to 100%, which is normal.

　　3. The energy storage battery will switch to the trickle charging mode when it is charged to high power. The terminal charging time will be lengthened, and the estimated charging time displayed by the meter will be biased.

　　4. When using the vehicle for the first time or after parking it for a long time, the SOC displayed by the instrument may be biased. It is recommended that the vehicle be fully charged to calibrate the SOC before using it for the first time or after parking it for a long time.

　　5. In order to keep the energy storage battery in the best condition, please use charging equipment to fully charge the energy storage battery regularly (it is recommended to fully charge it at least once a week).

　　6. To ensure the safety of energy storage batteries, vehicles should be kept away from flammable and explosive items, fire sources and various hazardous chemicals.

　　7. The vehicle should be charged and parked away from heat sources and avoid prolonged exposure to sunlight, otherwise it will reduce the service life of the energy storage battery.

　　8. In order to ensure long-term performance, avoid continuously exposing the vehicle to an environment with a temperature greater than 60°C or less than -30°C for more than 24 hours.

　　9. When the vehicle is not used for a long time (more than 7 days), the battery power should be kept at 40%~60%, otherwise the service life of the energy storage battery will be reduced. If the vehicle is not used for more than 3 months, it must be checked every 3 months. The energy storage battery must be fully charged before being discharged to 40%~60%. Otherwise, the energy storage battery may be over-discharged, reducing battery performance, or even being damaged, resulting in vehicle failure and damage.
