Abstract
The exemplified systems and methods provide fixed and exchangeable energy storage and delivery system in an electrified vehicle architecture with multi-mode controls. The exchangeable energy storage are configured to be optional and ultra-portable. The integration of fixed and exchangeable energy storage provides a vehicle configuration that is further optimized for size, weight, and convenience.
Claims18
An energy storage system of an electric vehicle or hybrid electric vehicle, comprising:
- a fixed energy storage module configured to provide power to at least a drive system comprising one or more electrical motors or other type of one or more loads, wherein the fixed energy storage module is sized in power output to solely and independently drive at least the drive system;
- a set of exchangeable energy storage modules configured to provide power to at least the drive system, wherein the set of exchangeable energy storage modules is sized in power output to solely and independently drive at least the drive system;
- and
- a multi-mode controller, the multi-mode controller having a processor and memory having instructions stored thereon, including:
- a first instruction to control a first energy flow direction, a first energy flow amount, and a first energy flow rate from at least one exchangeable energy storage module of the set of exchangeable energy storage modules to the drive system in a first mode;
- a second instruction to determine when the at least one exchangeable energy storage module has a discharge rate corresponding to a maximum allowable discharge rate for the at least one exchangeable energy storage module when directing energy flow to the drive system;
- a third instruction to determine available power associated with the energy flow of the at least one exchangeable energy storage module as the at least one exchangeable energy storage module directs energy flow to the drive system;
- a fourth instruction to control a second energy flow direction, a second energy flow amount, and a second energy flow rate from the fixed energy storage module to the drive system in a second mode based on the determination that the at least one exchangeable energy storage module has a discharge rate corresponding to a maximum allowable discharge rate for the at least one exchangeable energy storage module;
- and
- a fifth instruction to control a third energy flow direction, a third energy flow amount, and a third energy flow rate from the at least one exchangeable energy storage to the fixed energy storage module in a third mode based on the determined available power associated with the energy flow of the at least one exchangeable energy storage.

An electric vehicle or hybrid-electric vehicle comprising:
- one or more electrical motors;
- a drive system coupled to the one or more electrical motors;
- a set of one or more fixed energy storage modules each configured to provide power to at least the drive system, wherein the set of one or more fixed energy storage modules collectively is sized in power output to solely and independently drive at least the drive system;
- a set of one or more exchangeable energy storage module bays, each bay of the one or more exchangeable energy storage module bays being configured to receive an exchangeable energy storage module configured to provide power to at least the drive system, wherein a set of exchangeable energy storage modules when placed in the set of one or more exchangeable energy storage module bays is configured in power output to solely and independently drive at least the drive system;
- and
- a multi-mode controller, the multi-mode controller having a processor and memory having instructions stored thereon, including:
- a first instruction to control a first energy flow direction, a first energy flow amount, and a first energy flow rate from at least one exchangeable energy storage module of the set of two or more exchangeable energy storage modules to the drive system in a first mode;
- a second instruction to determine when the at least one exchangeable energy storage module has a discharge rate corresponding to a maximum allowable discharge rate for the at least one exchangeable energy storage module when directing energy flow to the drive system;
- a third instruction to determine available power associated with the energy flow of the at least one exchangeable energy storage module as the at least one exchangeable energy storage module directs energy flow to the drive system;
- a fourth instruction to control a second energy flow direction, a second energy flow amount, and a second energy flow rate from the fixed energy storage module to the drive system in a second mode based on the determination that the at least one exchangeable energy storage module has a discharge rate corresponding to a maximum allowable discharge rate for the at least one exchangeable energy storage module;
- and
- a fifth instruction to control a third energy flow direction, a third energy flow amount, and a third energy energy flow rate from the at least one exchangeable energy storage to the fixed energy storage module in a third mode based on the determined available power associated with the energy flow of the at least one exchangeable energy storage.
