Battery cabinet discharge current limit

What is a discharge current limit?

The discharge current limit (sometimes referred to as DCL for short, or load current limit) represents the maximum amount of current (measured in amps) that can be pulled or drawn from the battery pack without damaging or exceeding system ratings.

How long can a battery be discharged?

Maximum 30-sec Discharge Pulse Current –The maximum current at which the battery can be discharged for pulses of up to 30 seconds. This limit is usually defined by the battery manufacturer in order to prevent excessive discharge rates that would damage the battery or reduce its capacity.

What is a good charge current for a battery?

(Recommended) Charge Current – The ideal current at which the battery is initially charged (to roughly 70 percent SOC) under constant charging scheme before transitioning into constant voltage charging. (Maximum) Internal Resistance – The resistance within the battery, generally different for charging and discharging.

What happens if a battery capacity is set to 60%?

When set to 60%, all capacity between 60% and 100% will be used to optimize self-consumption. And 0% to 60% will be used in case of a mains outage. Note that the minimum SoC parameter - as configured in the CCGX - may be amended on a daily basis by the BatteryLife algorithm. Battery Voltage. See Dynamic Cut-off section, further down below.

What is a 'empty state' of a battery?

It is this voltage that generally defines the “empty” state of the battery. Capacity or Nominal Capacity (Ah for a specific C-rate) – The coulometric capacity, the total Amp-hours available when the battery is discharged at a certain discharge current (specified as a C-rate) from 100 percent state-of-charge to the cut-off voltage.

What happens if a battery reaches 85% SoC?

The value is increased once a day when the battery reaches the lower limit for the first time. When the battery reaches 85% SoC on the day, the increment for that day is canceled and the limit remains the same as the previous day. If the battery reaches 95% on any day, the dynamic discharge limit is lowered by 5%.
