Features of power lithium-ion batteries
① The working voltage of a single cell in a power lithium-ion battery is as high as 3.7V, which is three times that of nickel-cadmium batteries and nickel-metal hydride batteries, and nearly twice that of lead-acid batteries. This is also an important reason why power lithium-ion batteries have higher energy.
② Power lithium-ion batteries are generally packaged in aluminum shells, which have the characteristics of small size, light weight, high capacity, no memory effect, and green environmental protection, and are now widely used.
③ It can be charged and discharged quickly at a high current of 2C. With a dedicated charger, the battery can be fully charged in 40 minutes at 1.5C. The starting current can reach 2C, which is not a feature of lead-acid batteries.
How to protect power lithium-ion batteries
1. Regularly check the tire pressure of your electric vehicle. In summer, don't overinflate them; in other seasons, keep them adequately inflated to save electricity.
2. When charging your vehicle, avoid frequent charging, as this can affect the lifespan of the lithium-ion battery pack. If possible, use slow charging instead of fast charging.
3. Charge the vehicle promptly when the battery level approaches 20%. Do not wait until the battery is completely depleted before charging. If the vehicle is frequently driven when the battery level is below 10%, the vehicle will enter a speed-limited state, causing over-discharge damage to the lithium-ion battery.
4. Under normal use, the vehicle should be fully charged at least once a month. The battery management system will promptly correct the SOC to prevent energy loss or SOC fluctuations caused by prolonged periods of incomplete charging.
5. Power lithium-ion batteries must not be stored in a discharged state. The longer they are left idle in a discharged state, the more severe the damage to the battery. Therefore, when the battery is not in use, it should be recharged once a month to better maintain its health.
