Battery Knowledge
1. What battery level？
Answer：Power indicates how much energy is currently stored in the battery。The common unit of electric quantity isWhOrkWh，The degree of daily speaking（kWh）It's a unit of electricity.。Think of the battery as a pool of water.，Electricity is the water in the pool.，The external discharge of the battery is equivalent to the external discharge of water from the pool.。
2. What is battery capacity?？
Answer：Container is the meaning of container.，Indicates the amount of power the battery is capable of storing。The larger the battery capacity，The more power you can store.。Think of the capacity as a pool.，Batteries of different capacities are equivalent to pools of different volumes.。
3. Which part of the meter shows the power?、Capacity？
Answer：The percentage of the current remaining battery is displayed on the large screen，The display position is shown in the figure below.。The battery capacity is engraved on the battery nameplate（The nameplate only reflects the information of the single battery pack.）Go，The battery nameplate is attached to the battery pack，The nameplate is shown in the figure below.：
4. After battery capacity decay，Will the charging capacity be reduced?？So the charging time is longer.，Or is it shorter?？
Answer：Battery capacity decay is equivalent to the accumulation of silt in the pool.，The water storage in the pool is reduced.，The amount of power that the battery can store is reduced。While the charging capacity of the charger remains unchanged，Less power is needed.，The charging time will be shorter.。
5. Relationship between battery capacity and temperature？When temperature is low，Is the charging capacity getting less?？
Answer：Temperature has an effect on the actual capacity of the battery，18°CTo 45°CThe interval of，The actual capacity of the battery is not much different from the standard value.，Below 18°CThe actual capacity of the battery will be slightly reduced，10°CThe lower the following temperature, the greater the impact on the actual capacity of the battery.。Like water in a pool.，The lower the temperature, the larger the ice.，There is still so much water.，But there is less water that can be released.。When temperature is low，Less electricity can be charged，There is less electricity that can be released.，There is a fraction of the energy that is“Freeze”I'm staying。
6. Effect of temperature on Vehicle endurance？
Answer：Cell temperature 18°CTo 45°CIt is a more suitable charging and discharging interval.，At this time, the Vehicle's endurance is the longest.。18°CThe actual capacity of the battery will be slightly reduced，10°CThe lower the following temperature, the greater the impact on the actual capacity of the battery.。The colder the place.，The worse the endurance of the whole car.。-20°C，The lithium battery of ordinary lithium iron phosphate basically loses its discharge capacity.，Auxiliary heating is required for external discharge。
7. How to correctly understand 10000 hours or 500000 kilowatt-hour electricity，SOHWarranty 70%This concept？
Answer：SOH，Battery health，It can be understood as the percentage of the current capacity of the battery to the factory capacity.。Batteries are subject to attenuation during use.，To put it simply,，The new battery can charge 10 kilowatt-hours when it is first bought.，After a few years of use.，The battery can only charge 7 degrees of electricity.。7÷10×100%=70%，That is, the current battery health is 70%。When the Vehicle has been in use for 10000 hour，It also guarantees a charge of 70%Power of factory capacity，Indicates that the battery status is acceptable。Or，When the accumulated throughput of the vehicle is 500,000 kilowatt-hour（Accumulated charging capacity of charging pile），It also guarantees a charge of 70%Power of factory capacity，Indicates that the battery status is acceptable。Two conditions，Whichever comes first。
