5 Configuration

5.1 Battery

5.1.1 In a Lead-Acid battery configuration, how shall be calculated the V NOMINAL value?

V NOMINAL value refers to the whole battery bank nominal voltage. Most batteries datasheets contain
information about the voltage of each battery but the whole battery bank voltage is needed.
The following example has been done using 12Vdc batteries and 8 batteries in series.
V NOMINAL = Nominal Voltage x NS = 12 x 8 = 96 V
Where:
- Nominal Voltage (V): nominal voltage per battery value taken from the datasheet.
- NS (batteries): number of batteries in the bank connected in series.
Important note: A wrong configuration of this parameter may cause damage to the battery bank and the ISS
1Play. Ingeteam will not accept any responsibility of any wrong configuration.
5.1.2 In a Lead-Acid battery configuration, how shall be calculated the CAPACITY (C20H)
and CAPACITY (C5H) values?
CAPACITY value refers to the amount of current available from the battery for a certain period. C20H includes
the current values that can be taken from the battery for 20 hours while C5H indicates the current to take for 5
hours. Both parameters are critically important to the SOC accuracy.
The following example has been done using 10 batteries in parallel.
CAPACITY (C20H) = Nominal Capacity (20 hours discharge) x NP = 7.2 x 10 = 72 Ah
CAPACITY (C5H) = Nominal Capacity (5 hours discharge) x NP = 5,9 x 10 = 59Ah
Where:
- Nominal Capacity (Ah): nominal capacity for a 20 hour discharge period, it is given per battery and
taken from the datasheet.
- NP (batteries): number of batteries in the bank connected in parallel.
Important note: A wrong configuration of this parameter may cause damage to the battery bank and to the
ISS 1Play. Ingeteam will not accept any responsibility of any wrong configuration.
5.1.3 In a Lead-Acid battery configuration, how shall be calculated I CHARGE and I
DISCHARGE values?
I CHARGE makes reference to the maximum current that can be put into the battery while it is in its charging
process.
The following example has been done using 8 batteries in series and each one has 35 A of charging current.
The batteries are not set in parallel, so the whole battery bank´s current is the same of one single battery.
I CHARGE whole battery bank = 35 A
I DISCHARGE makes reference to the maximum current that can be taken from the battery while it is in its
discharging process. The same example is valid for discharging current.
Important note: if the charge/discharge current is not specified in the datasheet, the value shall be asked to
the manufacturer in order to get a suitable current. A wrong configuration of this parameter may cause
damage to the battery bank and to the ISS 1Play. Ingeteam will not accept any responsibility of any wrong
configuration.
