Battery Specifications and Accountability
|Discharge Limits – (Voltage & Current)||Battery||Protection||Notes|
|Continuous Discharge current||200A||1C continuous|
|Surge Discharge Current – 30 seconds||600A||3C transient. Typically repeated for every lift or peak load.|
|Electronic Current trip limit – analogue||550A||If the electronic current limit option is enabled – Note 1*|
|Electronic trip Retry time – analogue||–||Time taken after current trip to retry connection|
|Pre-Charge current limit – Note 1*||550A||Automatically provided if electronic current limit is enabled|
|Electronic Overload – Digital||Optional with either, I²t , max current, or Custom profiles|
|Internal Battery Fuse||400A||I²t = 610 000 A|
|Minimum battery voltage||47.2V||Battery will cutout here, regardless of indicated SOC|
|ABSOLUTE Minimum Battery Voltage||43.4V||Internal electronics Disabled! Please see battery protection.|
Note 1*. Electronic current limit is optional and adjustable between 500-1000A. It will act as a automatic pre-charge for connection to inverters. For motive applications, in particular old lead machines, pre-charge or current limit prevents startup, and not desirable.
Charge Limits - (and charger settings)
|Charge Limits – (and charger settings)|
|Maximum Continuous Charging Current||150A||Preferred range is 100A to 150A, set for constant current CC.|
|End of Charge voltage||56V||55.6V to 56.0V max set as endpoint CV voltage|
|Balancing charge voltage or current||56.2V||56.0V-56.3V OR charge at constant current (CC) of 400mA|
|Charger voltage range||48V||Charger voltage must be within normal 48V limits.|
|Battery maximum voltage self cut out||56.4V||Battery will cutout, preventing further charging, NOTE 3*.|
|Peak transient charger voltage||100V||*Peak transient voltage after battery self disconnects|
|Charger Lead Inductive Energy||75J||NOTE 4*. However, Typical 2m length lead installations are of no concern.|
|NOTE 3*. If battery self cuts out from over voltage it will still be available for discharge through reverse diode.|
NOTE 4*. This is the maximum charger lead Inductive energy battery cutout can absorb ( 1/2 I²L < 75J ).
NOTE 1*. When the internal electronics are disabled, the battery enters a dormant state. In this state the battery will be inactive, not connected and not available for normal recharge or use. It can be recharged but it MUST be recharged with a constant current that must not exceed 500mA (450mA preferred) and voltage less than 65V (e.g. Balancell hockey PUK charger). If left for more than 6 months in this dormant state, then it should NOT be recharged and battery needs to be returned for a service and cell checkup.
