1 电池常用术语集锦 电池常用术语（一） Battery Glossary A～C D～L M～Q R～Z A—C Ampere hours (Ah) - The unit of measure used for comparing the capacity or energy content of batteries with the same output voltage. For automotive (Lead Acid) batteries the SAE defines the Amphour capacity as the current delivered for a period of 20 hours until the cell voltage drops to 1.75 V. Strictly - One Ampere hour is the charge transferred by one amp flowing for one hour. 1Ah = 3600 Coulombs. Battery Management System (BMS) - Electronic circuits designed to monitor the battery and keep it within its specified operating conditions and to protect it from abuse during both charging and discharging. Battery Monitoring - Sometimes confused with BMS (above) of which it is an essential part, these circuits monitor the key operating parameters (current, voltage, temperature, SOC, etc.) of the battery and provide information to the user. Bobbin - A cylindrical cell design utilizing an internal cylindrical electrode and an external electrode arranged as a sleeve inside the cell container. C Rate - C is a value which expresses the rated current capacity of a cell or battery. A cell discharging at the C rate will deliver its nominal rated capacity for 1 hour. Charging and discharging currents are generally expressed as multiples of C. The time to discharge a battery is inversely proportional to the discharge rate.  NC is a charge or discharge rate which is N times the rated current capacity of the battery where N is a number (fraction or multiple)  CN is the battery capacity in AmpHours which corresponds to complete discharge of the battery in N hours (N is usually a subscript). Also written as the N-Hour...
