Abstract

A battery monitoring system including an on-site battery event monitor (BEM) that sends out battery-related data to a server over a wide area network (WAN). The BEM sends out data in a broadcast (or unicast manner) to predetermined server(s) without being queried or polled. This improves network security and data security and also eliminates the need for on-site network configuration and administration.

Claims

1. A BEM for use in a battery monitoring system for monitoring a battery site having a set of battery(ies) that includes at least one battery, the battery monitoring system including a communication network and a first server sub-system, the BEM comprising:

a data collection module;

a broadcast module;

a data-collection connector hardware set; and

a network connector hardware set;

wherein;

the data-collection connector hardware set is connected to said battery site so as to receive battery-related data therefrom;

the data collection module is connected to said data collection connector hardware set so as to receive the battery-related data therefrom;

the broadcast module is connected to the data collection module to;

(i) receive the battery-related data, (ii) convert the battery-related data into a form and format suitable for being data communicated over a communication network, and (iii) designate the first server sub-system;

the network connector hardware set is connected to the broadcast module to;

(i) receive the battery-related data, in the form and format suitable for being data communicated over a communication network; and

(ii) send the battery-related data over the communication network to the first server sub-system as designated by the broadcast module; and

the broadcast module and the network connector hardware set are further in communication so that the battery-related data over the communication network to the first server sub-system on a broadcast basis, and so that the BEM is not capable of receiving any substantive data communications from the communication network.

2. The BEM of claim 1 further comprising a housing, wherein the data collection module, the broadcast module, the data-collection hardware set and the network connector hardware set are all located on the housing.

3. The BEM of claim 1 wherein:

the data collection module set receives at least some of the battery-related data in analog form; and

the data collection module converts all analog form battery-related data into corresponding digital form battery related data before sending the battery related data to the broadcast module.

4. The BEM of claim 1 wherein the battery-related data sent from the data collection module to the broadcast module includes the following types of battery-related data:

(i) battery temperature, (ii) ambient temperature, (iii) float current, (iv) battery discharge current, (v) battery recharge current and (vi) battery voltage data.

5. The BEM of claim 4 wherein the battery voltage data is battery string voltage data.

6. The BEM of claim 1 wherein:

the communication network includes the internet; and

the broadcast module is further structured to put the battery-related data into a form and format for being communicated over the internet.

7. The BEM of claim 1 wherein the network connection hardware set and the broadcast module are structured so that the BEM is not capable of receiving any substantive data communications from the communication network.

8. The BEM of claim 1 wherein the battery site further includes a battery bus and the data collection module is structured to form a wired connection with the battery bus.

9. The BEM of claim 1 wherein the communication network includes a LAN at the battery site and the network connector hardware set is further structured to form a data communication connection with the LAN.

10. The BEM of claim 9 wherein the data communication between the network connector hardware set and the LAN is a wired connection.

11. The BEM of claim 1 wherein the network connection hardware set and the broadcast module are structured so that the battery-related data is sent to the designated first server sub-system on an at least substantially continuous broadcast basis.

12. The BEM of claim 1 further comprising a housing, wherein the data collection module, the broadcast module, the data-collection hardware set and the network connector hardware set are all located in the housing.
