Battery
A battery is characterised by two sizes: tension and capacity.
Tension:
Each element has a nominal tension, which depends on the type of battery (no
matter what size).
In order to reach higher tension, many elements are connected in series, so
creating a “BATTERY” of elements.
The number of elements is calculated by dividing the nominal tension of the
battery for the tension of each single element in the table:
Capacity:
It is the quantity of electric charge that the batteries can supply to an external circuit before the tension
decreases under the final limit value and it is obtained by multiplying the intensity of the discharging
current I, expressed in ampere (A), for the discharging time t expressed in hours (h): C = I x t.
The traction battery capacity is normally referred to the discharging system of 5h: C5 = I x 5h.
The capacity values that can be recharged by the battery chargers can be found in the description of the
Charging Curve (this value is not present in the curves able to charge any capacity).
