Abstract

A wiring harness for a battery and inverter system includes a main cable. It further includes an inverter connector configured to plug the main cable into an inverter module. It further includes a first spur of the main cable terminating in a first-type battery device connector. It further includes a second spur of the main cable terminating in a second type battery device connector.

First claim

What is claimed is:

1. A wiring harness for an energy storage system, comprising:
a main trunk;
an inverter connector configured to plug the main trunk into an inverter module, wherein the inverter connector facilitates connection to:
a positive DC power bus;
a negative DC power bus; and
a neutral power bus;

a first spur of the main trunk terminating in a first-type energy storage device connector, wherein the first-type energy storage device connector facilitates connection of:
a positive terminal of a first energy storage device to the positive DC power bus; and
a negative terminal of the first energy storage device to the neutral power bus; and

a second spur of the main trunk terminating in a second-type energy storage device connector, wherein the second-type energy storage device connector facilitates connection of:
a positive terminal of a second energy storage device to the neutral power bus; and
a negative terminal of the second energy storage device to the negative DC power bus.

2. The wiring harness of claim 1 , wherein the inverter module is effectively connected to a plurality of energy storage devices by plugging in the first-type energy storage device connector and the second-type energy storage device connector.

3. The wiring harness of claim 1 , wherein the inverter module further comprises an inverter-end ground pin.

4. The wiring harness of claim 3 , wherein a ground line connected to the inverter-end ground pin is daisy chained through a plurality of energy storage devices.

5. The wiring harness of claim 4 , wherein the daisy chaining is facilitated at least in part by a jumper internal to an energy storage device.

6. The wiring harness of claim 1 , wherein the inverter module further comprises an inverter-end set of communications pins.

7. The wiring harness of claim 6 , wherein communications lines connected to the inverter-end set of communications pins are daisy chained through a plurality of energy storage devices.

8. The wiring harness of claim 7 , wherein the communications lines are terminated by a resistor at an end of the main trunk.

9. The wiring harness of claim 7 , wherein the inverter module and the plurality of energy storage devices communicate bidirectionally.

10. The wiring harness of claim 9 , wherein the inverter module and the plurality of energy storage devices communicate bidirectionally via a controller area network bus.
