SECTION 6: BATTERY CHARGING
A. BATTERY CHARGING CYCLES
If you are new to the use and maintenance of an electric vehicle, there are some practical aspects of
battery charging cycles with which you should become familiar.
The act of recharging your battery is in many ways similar to refilling the fuel tank on a gasoline or
diesel vehicle: If you fill the “tank” halfway, you will only go half as far before having to fill up again.
A battery, however, diverges from this comparison in that a partial refill of a fuel tank will not affect
the tank’s future capacity. A battery, on the other hand, will be negatively affected by frequent partial
recharges.
As the chart below indicates, (Figure 6-1) the range of a “fast charge” is typically between the 20%
and 80% capacity range. Depending on the intensity of usage, it may occasionally become necessary
to recharge a battery during the course of the day. At such times, a short charge will likely fail to
extend the charged state of the battery beyond the 80% charge. Beyond the 80% point, standard
charging procedures require significantly more time to push the charge further into this upper 20%
range. (Figure 6-2)
