6 Frequently Asked Questions about “The maximum charging current allowed by the battery pack”
What is the maximum charge current for a battery?
Each of these battery contains a BMS that the manufacturer supports a recommended max charge current of 50Ah. Current is measured in Amps. Ah is Amps x Time. So lets use the proper terminology.
What is a charge & discharge limit?
This section allows for configuring the settings related to the current limits (both charge and discharge) that the BMS will use to protect the battery pack. This is the maximum amperage (unit is 1 amp) that the pack is allowed to accept (charge) or output (discharge).
What if the pack current limit is 50A?
If this value were set to 50A and the pack current limit is 50A then there would be 5.0v on the analog output line. This is the maximum charge current limit (CCL) that the BMS will enforce when the BMS is in CHARGE mode (when Charge Power is energized to +12v).
How many volts does a battery pack have?
Example: Assuming the battery pack current limit is 50A and this value is set to 100A, then 2.5v would be output on the analog current limit output pin. If this value were set to 50A and the pack current limit is 50A then there would be 5.0v on the analog output line.
How many amps should a 120ah battery charge?
The ideal charging current for a 120Ah battery is 24 amps when the battery is fully discharged but when the SOC is above 80% the amps will gradually start to decrease maximum charging current for 150Ah battery should not be above 30 amps Recommended maximum charging current for 200Ah battery is 40 amps
Can a battery pack be protected if a vehicle controller knows power limits?
These voltage limits will have to be applied anyway, but they tend to be a hard stop. If the vehicle controller knows the current/power limits ahead of time then the battery pack can be protected and the user can be limited more gradually to avoid the sudden loss of power.
