Vehicle system with batteries in series
A vehicle system is provided and includes a 12 volt alternator and a 24 volt wound rotor configured for acceptance in the 12 volt alternator.
1. A vehicle system, comprising:
an alternator configured to independently charge a first battery having a first voltage and a second battery connected in series with the first battery; and
a rotor having a rotor field winding which is powered by a second voltage of the first and second batteries, wherein the second voltage is greater than the first voltage.
2. The vehicle system of claim 1 , wherein the first and second batteries are 12 volt batteries.
3. The vehicle system of claim 2 , wherein the rotor is a 24 volt wound rotor and the alternator further comprising a 12 volt wound stator.
4. The vehicle system of claim 1 , wherein the second voltage is substantially twice the first voltage.
5. The vehicle system according to claim 1 , further comprising one or more additional batteries in series with the first and second batteries to power the rotor field winding.
