Abstract
Embodiments disclosed herein relate to a battery energy storage system (BESS) that can be used to store energy that is produced by conventional sources (e.g., coal, gas, nuclear) as well as renewable sources (e.g., wind, solar), and provide the stored energy on-demand.
Claims18
A battery energy storage system comprising:
- a plurality of battery packs;
- a string controller coupled to the plurality of battery packs and configured to control charging and discharging of the plurality of battery packs via a power control system that is external to the battery energy storage system;
- and
- an array controller coupled to the string controller and configured to instruct the string controller to charge or discharge the plurality of battery packs via a first communication bus,
- wherein the array controller is coupled to a system controller that comprises a communication interface that is configured to couple to a communications network.
2 more elements
A battery energy storage system comprising:
- a battery pack array comprising n battery pack strings, wherein each battery pack string comprises m battery packs connected in series;
- n string controllers, wherein each string control box is coupled to one of the n battery pack strings and configured to control charging and discharging of the m battery packs;
- and
- an array controller configured to instruct the n string controllers to charge or discharge each of the m battery packs via control area network (CAN) bus, wherein n is greater than or equal to 2 and m is greater than 2,
- wherein the array controller is coupled to a system controller that comprises a communication interface that is configured to couple to a communications network, and is further configured to receive instructions over the communications network and instruct the n string controllers to charge or discharge each of the m battery packs in response to receiving the instructions.
