Community energy storage system with battery bank deactivation
A community energy storage system comprises a cabinet, at least one battery bank mounted within the cabinet, the at least one battery bank comprising a plurality of battery modules electrically coupled to one another in series; and processing structure for monitoring at least one parameter of each of the battery modules, and in the event that the at least one parameter is outside of a threshold value, deactivating the at least one battery bank.
1. A community energy storage system comprising:
a cabinet having at least two compartments, each compartment having a door providing selective access thereto;
at least one non-conductive terminal rail mounted within each compartment of the cabinet opposite the door,
a plurality of terminal connectors mechanically connected to each non-conductive terminal rail, each terminal connector having a first end adjacent a first side of the non-conductive terminal rail and a second end adjacent a second side of the non-conductive terminal rail, the first and second ends electrically coupled to one another;
at least two battery banks, each battery bank positioned within a respective one of the compartments and comprising a plurality of battery modules, each one of the plurality of battery modules comprising a positive terminal and a negative terminal extending from an end thereof, each positive and negative terminal configured to mechanically engage and electrically couple to the first end of a respective one of the plurality of terminal connectors such that the battery module is readily removable from the compartment via the door; and
a plurality of connectors configured to electrically couple the second ends of the plurality of terminal connectors to one another such that the plurality of battery modules in each battery bank are electrically coupled in series,
wherein the at least two battery banks are simultaneously active during normal operation.
2. The community energy storage system of claim 1 wherein each positive and negative terminal is mechanically engaged with the respective one of the plurality of terminal connectors via friction fit.
3. The community energy storage system of claim 2 wherein each battery module is readily removeable by disengaging the positive and negative terminals from the respective one of the terminal connectors.
4. The community energy storage system of claim 1 further comprising switching gear configured to selectively activate and deactivate each battery bank.
5. The community energy storage system of claim 4 further comprising processing structure positioned within a third compartment of the cabinet and configured to:
monitor at least one parameter of each of the battery modules; and
send a signal to the switching gear to deactivate one of the battery banks when a battery module of the one of the battery banks has at least one parameter outside of a threshold value.
6. The community energy storage system of claim 5 where the at least one parameter is at least one of temperature, voltage, current, state of charge, cell capacity and efficiency.
7. The community energy storage system of claim 5 further comprising a display screen positioned within the third compartment of the cabinet, the processing structure and the display screen configured to display to indicate to a user which battery module has a parameter value outside of the threshold value.
8. The community energy storage system of claim 5 further comprising a heating and cooling system configured to selectively provide heating and cooling to the battery banks.
9. The community energy storage system of claim 8 wherein the at least one parameter is temperature and the processing structure is configured to activate the heating and cooling system to heat or cool the battery banks based on the temperature.
