selection of a battery should be done upon the following
criteria, starting from the most important :
- Energy / weight ;
- Charge (Number of cycles) ;
- Life time, price ;
- Maintenance ;
- Voltage, size (depending on the application) ;
lead batteries are the first to have been developped.
The investment cost is limited, but its charcateritics
are limited . The complete charging requires around 6
hours. That's why some vehicles are fitted with removable
pack of batteries allowing to inter-change them quickly.
For the go-karts, it is possible to do partial discharge
- charge. In such case, the charging time is equivalent
to the discharge time.
Nickel-Cadnium batteries use more modern technology.
The autonomy and life time are higher but the cost is
more important. The also withstand power of charge 3 time
higher than normal batteries. The charge / discharge time
rate is therefore more interesting.
batteries can be mounted in parallel or in series.
