Abstract
A system includes housing having a positive terminal and a negative terminal and one or more energy storage devices disposed therein. One system includes a first energy storage device that operates at a first state of charge level and a second energy storage device that operates at a second state of charge level. The second state of charge level is greater than the first state of charge level.
Claims21
An energy source system, comprising:
- a housing comprising a positive terminal and a negative terminal;
- a first energy storage device disposed in the housing and configured to operate at a first state of charge level;
- and
- a second energy storage device disposed in the housing and configured to operate at a second state of charge level, wherein the second state of charge level is greater than the first state of charge level.
1 more element
An energy storage system, comprising:
- a housing comprising a positive terminal and a negative terminal;
- a first energy storage device disposed in the housing and comprising a first charging rate during charging of the energy storage system;
- a second energy storage device disposed in the housing and comprising a second charging rate during charging of the energy storage system, wherein the first charging rate is substantially greater than the second charging rate;
- and
- a controller coupled to the first energy storage device and the second energy storage device and configured to control charging of the energy storage system during a regenerative braking event associated with operation of a vehicle such that the first energy storage device is configured to receive regenerative energy associated with the regenerative braking event at the first charging rate.
2 more elements
An energy source system, comprising:
- a housing comprising a positive terminal and a negative terminal;
- a first energy storage device disposed in the housing and configured to accept charge at a first charge acceptance rate;
- and
- a second energy storage device disposed in the housing and configured to accept charge at a second charge acceptance rate, wherein the second charge acceptance rate is less than the first charge acceptance rate.
