Basic specifications: NO. Project Specifications 1 Charging voltage 16.8V 2 Nominal voltage 14.8V 3 Load voltage ≥14.4V 4 Nominal capacity 2000mah 5 Standard charging method 0.2C (constant current) charging to 16.8 v and CV (constant voltage 16.8V) charge until the charge current ≤ 0.02C 6 Maximum charge current 2A 7 Maximum continuous discharge current 2A 8 The maximum current 5A 9 The discharge cut-off voltage 11.2V 10 Using temperature Charging: 0 ¡æ ~45 ¡æ discharge:-20 ¡æ ~45 ¡æ 11 Storage temperature 23 ± 5 ℃ Electrical properties: NO. Project Test method and conditions Standard 1 Standard charge Constant current charging 0.2C to 16.8V and 16.8V charge until the charge current with constant pressure ≤ 0.02C 2 Initial capacity The volume refers to the standard charge, to 11.2V 0.2C discharge cut-off voltage emits capacity. ≥2000mah 3 Cycle life Test conditions: charging: 0.2C constant current and constant voltage charging to 16.8V globe current 0.02C discharge 0.2C discharge to 11.2V when the capacity drops below the initial capacity at 80%, the complete cycle is defined as the cycle life of the battery pack. ≥ 500 4 30-day charge retention rate Standard charge, stored under No.3.5 condition for 30 days, and then to 11.2V out of 0.2C discharge capacity. And then press method 3.1.1 battery charge, 0.2C discharges to 11.2V. Volume retention capacity recovery rate ≥ ≥ 90% 95% 5 The initial internal resistance Half charge State, measuring AC impedance of the AC 1KHz ≤120mΩ 6 Voltage Outgoing voltage 14.8V 7 Temperature characteristics 1. at 23 ± 5 ℃, 3.1.1 will charge the battery. 2. at different temperatures, with 0.3C of current to constant-current discharge cut-off voltage 11.2V. To 23 percent when calculated on a capacity basis. -20: discharge volumes 0 ℃ ≥ 70%: the discharge capacity of 23 ℃ ≥ 80%: discharge capacity =100%55 ℃ discharge capacity ≥ 95% 5. safety: Project Standard Adoption of the Short circuit External short circuit the battery 10min, external line resistance should be less than 5M. The battery should be no explosion, no fire Pass Overcharge At 23 ± 5 ℃ condition, battery 1C charge to 15V, and constant voltage 15V current fall close to 0 a, monitor the battery temperature, when the temperature drops below the peak of about 10 ℃, to stop the tests. Battery should not fire and not explode. Pass Over discharge At 23 ± 5 ℃ condition according to standard discharge requirements after discharge to voltage, external 30 ω load discharged 24 hours. batteries should be no explosion, no fire, no leakage. Pass Heating Battery within 85 ° c ± 2 ° c thermostat and thermal insulation 120min. The battery should be no explosion, no fire Pass Acupuncture Φ 3mm~ 8mm high temperature wire, at a 10-40mm/s speed, perpendicular to the direction of the battery plates, at least throughout the cell (the wire stays in the cell). Battery explosion, no fire Pass Extrusion Orientation to perpendicular to the battery press, squeeze to the battery module 85% of the original size, keep 5min and squeeze again to the battery module 50% of the original size.
