Patent Images
1. A parallel power back-up system comprising:
- a performance battery having;
a rate greater than 2C; and
a cycle life greater than 300 cycles at C rate;
a bulk energy storage system; and
a controller configured to;
determine when grid power has failed,connect the performance battery to a bus in response to determining that the grid power has failed,initiate a timer after connecting the performance battery to the bus, andconnect, at the expiry of the timer, the bulk energy storage system to the bus;
wherein the performance battery and the bulk energy storage system are connected in parallel to the bus through the controller.

Abstract
System and methods of supplying power to a load are provided. A module monitors electrical grid power. When the grid power fails the module initially provides power from a performance battery. When a bulk energy power system has warmed-up/activated, the module switches the power to the load from the performance battery to the bulk energy power system.

19. A method of providing back-up power through a bus, the method comprising:
-
determining, by a controller, if grid power has failed; connecting, by the controller, a performance battery to the bus, the performance battery having a rate greater than 2C and a cycle life greater than 300 cycles at C rate; initiating, by the controller, a timer after connecting the performance battery to the bus; continuously monitoring in duration of the timer, if the grid power is back online; and ending the timer, if the grid power is back online, and disconnecting the performance battery from the bus, else connecting at the expiry of the timer, a bulk energy storage system to the bus; wherein the performance battery and the bulk energy storage system are connected in parallel to the bus through the controller.

20. A system for providing power back-up to a load, the load being connected to a bus, the system comprising:
-
a performance battery having a rate greater than 2C and a cycle life greater than 300 cycles at C rate; a bulk energy storage system; and a power back-up switching module configured to; determine if grid power to the load has failed, connect the performance battery to the bus, initiate a timer after connecting the performance battery to the bus, continuously monitor, in duration of the timer, if the grid power is back online, and if the grid power is back online, end the timer and disconnect the performance battery from the bus, else connect, at the expiry of the timer, the bulk energy storage system to the bus; wherein the performance battery and the bulk energy storage system are connected in parallel to the bus through the power switching module.
