Capacity
defini­tion
The nominal capacity origi­nates from the manufac­tu­rer’s data sheet, if available. When the data sheet is unavailable, the nominal capacity is estimated. Batemo measured the C/10 capacity by dischar­ging the cell at an ambient tempe­ra­ture of 25°C from 100% with a constant current of 0.29A (0.1C) until reaching the voltage of 2.5V. The thermal boundary condi­tion is free convection.

C/10 2.71 Ah
Current
defini­tion
All quanti­ties are measu­re­ment results from the Batemo battery labora­tory.
The conti­nuous current is the highest current that comple­tely discharges the cell without overhea­ting it. There­fore, the cell is discharged from 100% state of charge (SOC) at an ambient tempe­ra­ture of 25°C with a constant current until a residual state of charge of 10% and either the lower voltage limit of 2.5V or 90% of the maximum surface tempe­ra­ture (72°C) is reached.
The peak current is the current that the cell can supply for 5 minutes. The cell is there­fore discharged from 100% SOC at an ambient tempe­ra­ture of 25°C with a constant current until it reaches either the lower voltage limit of 2.5V or the maximum surface tempe­ra­ture of 80°C after 5 minutes. For cells that reach the maximum surface tempe­ra­ture, the measured current is taken directly as the peak current. For cells that do not reach the maximum surface tempe­ra­ture after 5 minutes because they reach the lower voltage limit first, the measured current is multi­plied by a correc­tion factor that estimates the current that would have heated the cell to the maximum surface tempe­ra­ture within 5 minutes.
The thermal boundary condi­tion is free convec­tion. These opera­ting conditions may be outside the cell manufacturer’s specification.

Discharge Charac­te­ristics

V4Drive_V18650HP30A_const

  • Discharge Charac­te­ristics: The electrical and thermal discharge behavior is strongly nonlinear.
  • Pulse Charac­te­ristics: The shape of diffe­rent current pulses changes strongly.
  • Energy Charac­te­ristics: The graph visua­lizes how much energy the cell can deliver when operated at diffe­rent powers.
  • Power Charac­te­ristics: The more power the cell supplies, the shorter it can deliver the power.
  • Thermal Charac­te­ristics: The greater the thermal losses, the more the cell heats up, resul­ting in higher depleted power.
