Abstract

A method, system, node and device are disclosed. A collector device configured to communicate with a vehicle system, a health node and at least one sensor is described. The collector device includes a communication interface configured to receive at least one measurement from the at least one sensor; and transmit battery data using at least one of a first communication link and a second communication link. The collector device further includes processing circuitry configured to determine the battery data based at least in part on the received at least one measurement; and determine at least one of the first communication link and the second communication link for transmitting the battery data to the health node. The at least one of the first and second communication links is determined based at least in part on a usability of the second communication link to transmit the battery data.

First claim

What is claimed is:

1 . A collector device configured to communicate with a vehicle system associated with a battery, a health node and at least one sensor, the collector device comprising:
a communication interface configured to:
receive at least one measurement from the at least one sensor; and
transmit battery data associated with the battery to the health node using at least one of a first communication link and a second communication link;
processing circuitry in communication with the communication interface, the processing circuitry being configured to:
determine the battery data based at least in part on the received at least one measurement; and
determine at least one of the first communication link and the second communication link for transmitting the battery data to the health node, the first communication link being associated with the collector device, the second communication link being associated with the vehicle system, the at least one of the first and second communication links being determined based at least in part on a usability of the second communication link to transmit the battery data, the usability of the second communication link being based on whether the second communication link is any one of restrictive and permissive to transmit the battery data.

2 . The collector device of claim 1 , wherein the at least one sensor is connected to the battery to provide the at least one measurement, and the at least one sensor is any one of:
external to at least one of the battery and the collector device; included in the battery; and included in the collector device.

3 . The collector device of claim 1 , wherein the at least one sensor is a hybrid sensor being configured to provide the at least one measurement usable by the collector device and another measurement usable by the battery.

4 . The collector device of claim 1 , wherein the first communication link is associated with a first network, and the second communication link is associated with a second network, the second network being any one of restrictive and permissive for the collector device to communicate with the health node using the second communication link and the second network.

5 . The collector device of claim 4 , wherein the processing circuitry is further configured to:
determine the usability of the second communication link further based on whether the second network is any one of restrictive and permissive.

6 . The collector device of claim 4 , wherein the processing circuitry is further configured to:
when the second network is restrictive, modify at least one parameter associated with the second communication link at least to transmit the battery data to the health node using the second communication link and the modified at least one parameter.

7 . The collector device of claim 4 , wherein the second network is restrictive when the vehicle system limits at least a set of the battery data to be transmitted using the second network.

8 . The collector device of claim 4 , wherein the determined battery data includes an identifier that causes the battery data to be routed through the second network when the battery data is transmitted.

9 . The collector device of claim 1 , wherein the communication interface is further configured to:
receive battery health information from the health node using at least one of the first and second communication links, the battery health information being based on the transmitted battery data.

10 . The collector device of claim 1 , wherein the collector device is configured to communicate with the vehicle system using an onboard diagnostic interface comprised in the vehicle system.

11 . A method in a collector device configured to communicate with a vehicle system associated with a battery, a health node and at least one sensor, the method comprising:
receiving at least one measurement from the at least one sensor; determining battery data associated with the battery based at least in part on the received at least one measurement; determining at least one of a first communication link and a second communication link for transmitting the battery data to the health node, the first communication link being associated with the collector device, the second communication link being associated with the vehicle system, the at least one of the first and second communication links being determined based at least in part on a usability of the second communication link to transmit the battery data, the usability of the second communication link being based on whether the second communication link is any one of restrictive and permissive to transmit the battery data; and transmitting the battery data to the health node using at least one of the first communication link and the second communication link.

12 . The method of claim 11 , wherein the at least one sensor is connected to the battery to provide the at least one measurement, and the at least one sensor is any one of:
external to at least one of the battery and the collector device; included in the battery; and included in the collector device.

13 . The method of claim 11 , wherein the at least one sensor is a hybrid sensor being configured to provide the at least one measurement usable by the collector device and another measurement usable by the battery.

14 . The method of claim 11 , wherein the first communication link is associated with a first network, and the second communication link is associated with a second network, the second network being any one of restrictive and permissive for the collector device to communicate with the health node using the second communication link and the second network.

15 . The method of claim 14 , wherein the method further includes:
determining the usability of the second communication link further based on whether the second network is any one of restrictive and permissive.

16 . The method of claim 14 , wherein the method further includes:
when the second network is restrictive, modifying at least one parameter associated with the second communication link at least to transmit the battery data to the health node using the second communication link and the modified at least one parameter.

17 . The method of claim 14 , wherein the second network is restrictive when the vehicle system limits at least a set of the battery data to be transmitted using the second network.

18 . The method of claim 14 , wherein the determined battery data includes an identifier that causes the battery data to be routed through the second network when the battery data is transmitted.

19 . The method of claim 11 , wherein the method further includes:
receiving battery health information from the health node using at least one of the first and second communication links, the battery health information being based on the transmitted battery data.

20 . A system, the system comprising a collector device, a vehicle system, and a health node:
the collector device comprising:
a first communication interface configured to:
receive at least one measurement from at least one sensor; and
transmit battery data associated with a battery to the health node using at least one of a first communication link and a second communication link;
