Abstract

A system includes an energy storage system having a plurality of batteries and a monitoring system operably coupled to the energy storage system. The monitoring system is configured to receive a first measurement corresponding to a characteristic from at least one of the plurality of batteries, determine a baseline from the first measurement, receive a second measurement from the at least one of the plurality of batteries, and compare the second measurement with the baseline to identify an issue with the at least one of the plurality of batteries. The monitoring system is also configured to perform a remediation action in response to the identified issue.

First claim

What is claimed is:

1. An energy storage system comprising:
a plurality of energy storage devices;
a plurality of sensors, a least one sensor sensing a temperature of at least one of the plurality of energy storage devices and at least one additional sensor being an air quality sensor sensing the air quality in a vicinity of the plurality of energy storage devices;
a plurality of switch devices configured to perform one of charging, discharging, or disconnecting at least one of the energy storage devices;
a climate control system; and
a monitoring system operably coupled to the plurality of sensors, the plurality of switch devices, and the climate control system, the monitoring system configured to:
for each of a plurality of operating conditions, determine a baseline temperature condition for each of the plurality of energy storage devices using sensor data collected during a first time period from at least one of the plurality of sensors;
determine a baseline level of air quality in the vicinity of the plurality of energy storage devices using air quality data collected during the first time period;
collect sensor data for each of the plurality of energy storage devices using the plurality of sensors for each of a plurality of operating conditions during a second time period;
determine an actual temperature level using sensor data collected during the plurality of operating conditions during the second time period;
compare the actual temperature level to the baseline level of air quality temperature and if the actual temperature level is below is above the baseline level of temperature, cause the climate control system to process the air in the vicinity of the plurality of energy storage devices until the temperature level is equal to or below the baseline temperature level; and
determine if the energy storage system is not being discharged and adjust the plurality of switch devices such that the measured characteristics of the energy storage devices are within acceptable operating conditions.

2. The system of claim 1 , wherein the monitoring system is further configured to compare the sensor data for each of the plurality of energy storage devices collected during the second time period to the baseline condition for each of the plurality of energy storage devices and if the sensor data from an energy storage device from the second time period differs from the determined baseline condition for that energy storage device, adjust the plurality of switch devices to correct the measured condition of the energy storage device.

3. The system of claim 2 , wherein the plurality of sensors comprises a temperature sensor for each of the plurality of energy storage devices.

4. The system of claim 2 , wherein the plurality of sensors comprises a voltage sensor in communication with at least one of the plurality of energy storage devices.

5. The system of claim 1 , wherein the monitoring system is further configured to compare the actual temperature level to a predetermined maximum temperature level and if the temperature level is the predetermined maximum temperature level, cause the climate control system to process the air in the vicinity of the plurality of energy storage devices until the temperature level is equal to or below the predetermined maximum temperature level.

6. The system of claim 1 , wherein the step of adjusting the plurality of switch devices comprises disconnecting at least one energy storage device using at least one of the plurality of switch devices.

7. The system of claim 1 , wherein the step of adjusting the plurality of switch devices comprises charging at least one energy storage device using at least one of the plurality of switch devices.

8. The system of claim 1 , wherein the step of adjusting the plurality of switch devices comprises discharging at least one energy storage device using at least one of the plurality of switch devices.

9. The system of claim 1 , further comprising a fire suppression system, and wherein the monitoring system is further configured to compare the actual air quality level and temperature levels to a predetermined air quality or temperature level indicative of combustion and if the actual air quality level is indicative of combustion, cause the plurality of switch devices to discharge the energy storage devices and cause the fire suppression system to activate.

10. A method of managing an energy storage system comprising:
determining a baseline temperature of one of a plurality of energy storage devices using temperature data collected during a first time period;
determining an actual temperature level using sensor data collected one of the plurality of energy storage devices during a second time period;
comparing the actual temperature level to the baseline temperature level and if the actual temperature level is below above the baseline level of temperature, cause a climate control system to process the air in the vicinity of the plurality of energy storage devices until the air temperature level is equal to or below the baseline temperature level; and
determining if the energy storage system is not being discharged and adjusting a plurality of switch devices configured to perform one of charging, discharging, or disconnecting at least one of the energy storage devices such that the measured characteristics of the energy storage devices are within acceptable operating conditions.

11. The method of claim 10 , further comprising:
determining a baseline condition for each of a plurality of energy storage devices using sensor data collected during a first time period;
comparing the sensor data for each of the plurality of energy storage devices collected during a second time period to the baseline condition for each of the plurality of energy storage devices and if the sensor data from an energy storage device from the second time period differs from the determined baseline condition for that energy storage device, adjusting a plurality of switch devices configured to perform one of charging, discharging, or disconnecting at least one of the energy storage devices to conform the measured condition of the energy storage device to the baseline condition.

12. The method of claim 11 , wherein the baseline condition comprises an energy storage device temperature for each of the plurality of energy storage devices.

13. The method of claim 11 , wherein the baseline condition comprises a voltage for each of the plurality of energy storage devices.

14. The method of claim 10 , further comprising: comparing an actual air quality level to a predetermined minimum air quality level and if the air quality level is below the predetermined minimum air quality level, causing a climate control system to process air in the vicinity of the plurality of energy storage devices until the air quality level is equal to or above the predetermined minimum air quality level.

15. The method of claim 14 , further comprising comparing the actual air quality level to a predetermined air quality level indicative of combustion and if the actual air quality level is indicative of combustion, discharging the energy storage devices and activating a fire suppression system.

16. The method of claim 10 , wherein the step of adjusting the plurality of switch devices comprises disconnecting at least one energy storage device.

17. The method of claim 10 , wherein the step of adjusting the plurality of switch devices comprises one of charging or discharging at least one energy storage device.

18. An energy storage system comprising:
