Battery Specifications and Accountability
|Discharge Limits – (Voltage & Current)
|Continuous Discharge current
|Surge Discharge Current – 30 seconds
|3C transient. Typically repeated for every lift or peak load.
|Electronic Current trip limit – analogue
|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*
|Automatically provided if electronic current limit is enabled
|Electronic Overload – Digital
|Optional with either, I²t , max current, or Custom profiles
|Internal Battery Fuse
|I²t = 2 050 000 A
|Minimum battery voltage
|Battery will cutout here, regardless of indicated SOC
|ABSOLUTE Minimum Battery Voltage
|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
|Preferred range is 100A to 150A, set for constant current CC.
|End of Charge voltage
|55.6V to 56.0V max set as endpoint CV voltage
|Balancing charge voltage or current
|56.0V-56.3V OR charge at constant current (CC) of 400mA
|Charger voltage range
|Charger voltage must be within normal 48V limits.
|Battery maximum voltage self cut out
|Battery will cutout, preventing further charging, NOTE 3*.
|Peak transient charger voltage
|*Peak transient voltage after battery self disconnects
|Charger Lead Inductive Energy
|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.
