Abstract
A vehicle power system includes circuitry including a transformer having a single primary coil and at least two secondary coils electrically isolated from one another, one of the secondary coils being electrically connected to a traction battery and another of the secondary coils being electrically connected to an auxiliary battery, and a controller configured to operate the circuitry to transfer power from the primary coil to each of the batteries at a same time.
Claims20
A vehicle power system comprising:
- circuitry including a transformer having a single primary coil and at least two secondary coils electrically isolated from one another, one of the secondary coils being electrically connected to a traction battery and another of the secondary coils being electrically connected to an auxiliary battery;
- and
- a controller configured to operate the circuitry to transfer power from the primary coil to each of the batteries at a same time.
A method for charging batteries of a vehicle comprising:
- cycling (i) switches electrically connected between a power source remote from the vehicle and a transformer having a single primary coil and at least two secondary coils electrically isolated from one another, one of the secondary coils being electrically connected to a traction battery and another of the secondary coils being electrically connected to an auxiliary battery, and (ii) switches electrically connected between the another of the secondary coils and the auxiliary battery to transfer power from the primary coil to each of the batteries at a same time.
A vehicle power system comprising:
- a transformer having a single input and dual outputs electrically isolated from each other;
- a traction battery electrically connected to one of the outputs;
- and
- an auxiliary battery electrically connected to the other of the outputs, wherein the transformer is configured to transfer power from the input to each of the outputs at a same time.
