1.使用后的电池，一般要求多长时间内需要补充电？最长可允许多长时间不补充电？When the battery needed to be charged after use? What is the maximum period without charge?
--我们建议1~2周内进行补充电。最大允许6个月内完成补充电，但是会影响电池容量和寿命。不补充电时间达到1年，电池失效。
Charging in 1-2 weeks is suggested after battery used. The maximum period is 6 months without charge, but that will badly affect the capacity and service life. 1 year without charge, the battery will be out of service.
2.电池在什么情况下会发生过放电？When the battery will be over discharged?
--没有BMS电池，放电终止电压可能会低于2.5V/单体以下，此时会发生过放电。电池过放，会引起爆炸起火，本质原因是：电池内部发生了不可逆的化学反应。
If no BMS battery, the discharge end voltage may be lower than 2.5V/cell, then over discharge will happen. That will cause explosion and fire. Because there are irreversible chemical reactions inside the battery.
3. 电池放电过程中的核电状态SOC和电池充放电循环寿命的容量值衰减有什么关系？What is the connection between the state of charge during battery discharge, and the battery capacity attenuation?
--两者虽然单位都是AH，但是他们没有关系。SOC表示电池单次充放电过程中，电池的带电量。电池容量表示电池100%充电条件下，所能携带的电量。是由电池内部化学材料的性质决定的。
No connection although both use AH as unit. State of charge means the carried charge in single charge/discharge. Battery capacity means the carried charge when 100% charged, decided by the battery chemicals inside.
