Agricultural vehicle having electrical driveline
An agricultural vehicle including a chassis and a rechargeable high voltage DC electric battery, the chassis incorporating an intermediate frame and an encapsulated power electronics unit located within the intermediate frame. Since the power electronics unit is separated from the electric battery, this allows for ready repair and/or replacement of the battery over the lifetime of the vehicle.
1. An agricultural vehicle comprising:
a chassis comprising two transversely fixed rear mounting supports and a third mounting point for pivotally mounting a front support, the front support extending transversely across the chassis; and
a rechargeable high voltage DC electric battery, wherein the chassis has an intermediate frame section with an encapsulated power electronics unit located within the intermediate frame section connected to the battery.
2. The agricultural vehicle of claim 1 , wherein the power electronics unit is integrated in the intermediate frame section of the chassis.
3. The agricultural vehicle of claim 1 , wherein the power electronics unit is integrated in the intermediate frame section below the battery.
4. The agricultural vehicle of claim 1 , further comprising an electrically powered driveline connected to the intermediate frame section.
5. The agricultural vehicle of claim 1 , wherein the intermediate frame section comprises left and right frame parts, each of the left and right frame parts connected at one end to a front frame part and at an opposite end to a rear frame part, each of the left and right frame parts being provided with one of the two rear mounting supports adjacent the rear frame part, and a bottom frame part extending between a lower region of each of the left and right frame parts, and the front and rear frame parts.
6. The agricultural vehicle of claim 5 , wherein the front frame part is provided with the third mounting point for pivotally mounting the front support.
7. The agricultural vehicle of claim 1 , wherein the battery is mounted to the chassis at each of the two rear mounting supports and the third mounting point.
8. The agricultural vehicle of claim 5 , wherein the bottom frame part is provided with a plurality of openings.
9. The agricultural vehicle of claim 8 , wherein at least one of the plurality of openings is transversely spaced from each other opening of the plurality of openings to allow access to the at least one of the plurality of openings.
10. The agricultural vehicle of claim 1 , further comprising at least one implement connector connected to the high voltage DC electric battery.
11. The agricultural vehicle of claim 8 , further comprising at least one implement connector connected to the high voltage DC electric battery wherein the at least one implement connector connects to the power electronics unit through at least one of the plurality of openings in the bottom frame part of the intermediate frame section of the chassis.
12. The agricultural vehicle of claim 10 , wherein the power electronics unit comprises at least one releasable connector to connect the at least one implement connector to the power electronics unit.
13. The agricultural vehicle of claim 10 , wherein the power electronics unit comprises a releasable connector to connect at least one releasable implement connector to the power electronics unit.
14. An agricultural vehicle, comprising:
a chassis;
a rechargeable high voltage DC electric battery, wherein the chassis has an intermediate frame section with an encapsulated power electronics unit located within the intermediate frame section connected to the battery; and
a power distribution unit and components of a transformer oil supply system connected to the battery.
15. The agricultural vehicle of claim 14 , wherein the power distribution unit and the components of the transformer oil supply system are mounted to the intermediate frame section.
16. An agricultural vehicle comprising:
a chassis;
a rechargeable high voltage DC electric battery;
an encapsulated power electronics unit; and
at least one high voltage connector connected to the high voltage DC electric battery by way of the power electronics unit, wherein the chassis incorporates an intermediate frame section in which the encapsulated power electronics unit is located, the intermediate frame section providing access for releasably securing the at least one high voltage connector to a lower region of the power electronics unit.
17. The agricultural vehicle of claim 16 , wherein the access is provided by a plurality of openings in a lower part of the intermediate frame section.
18. The agricultural vehicle of claim 17 , wherein at least one of the plurality of openings is transversely spaced from each other opening of the plurality of openings.
