Abstract

Comprehensive, Systematic and Practical Engineering/Manufacture/Operation/Management System for Electric Vehicle with dual usage for Decentralized Smart Power Storage that includes: Smart Battery Subsystem (SBS), which includes the Smart Battery Assembly (SBA) with embedded computer/data logger and the Battery Compartment (BC) on the EV and in the Swapping Recharge Stations (RS); the computers on the EV and RS; hardware and software for the SBA Exchange/Recharge/Maintenance/Management/Billing Subsystem; the Smart Decentralized Energy Storage Subsystem for on-line, off-line and/or emergency uses. The SBA can be swapped at RS or recharged at home or any recharge stations, or dismounted/mounted easily in garage or during roadside service. The SBA could include the built-in charge controller and inverter. All the subsystems are indispensable parts or options for this invented integrated system.

Claims

1. A Electric Vehicle Design, Engineering, Manufacturing, Operation, and Management System, serving dual purpose as a part of Smart Energy Storage System (EV-SESS) for on-line network connected, and/or off-line storage for decentralized power generation, and/or emergency energy source for homes and other electricity users, that comprises of a multitude of integrated subsystems:

a. the Electric Vehicle Subsystem (EV) operating on a rechargeable Smart Battery Assembly (SBA) carried in an onboard built-in battery compartment (BC);

b. the SBA Subsystem;

c. BC Subsystem;

d. the SBA recharge/Swap/Maintenance/Management/Billing Station Subsystem (RS) distributed in the entire EV service territory;

e. Computerized Management Subsystem (CMS) includes finance and billing management function.

2. EV as set forth in claim 1, is a vehicle powered by electricity stored in the SBA. The EV should be equipped with at least one BC onboard to contain SBA, also an accessory battery (AB) to power the electric devices, computer(s) except the propulsion motor(s) with and without the main SBA onboard the EV. The AB shall be recharged by the SBA, by plug in, by decentralized power sources. EV means any land, water, submerged or air vehicles, manned or unmanned.

3. SBA as set forth in claim 1, comprises of rechargeable storage batteries or other energy storage/production devices such as super-capacitor, flywheel batteries, fuel cells, micro-turbine, micro-hybrid power pack, etc. in a self-contained package of a standardized geometry;

with embedded microprocessor/data-storage;

with quick automatic connecting main electric connectors for charge/discharge, computer interface—

wireless and/or connectors, that allows dependable connections when the SBA is inserted and seated to the predetermined position in the BC;

with temperature control/cooling fans;

that the construction, material and structure of the SBA shall be manufactured to facilitate and endure frequent insertion/retrieval/handling to and from between the BC of EV, the BC of RS, on the rollers, conveyor or specially designed material handling vehicle/lift, or onto or from a manual truck that allows small and home garage or roadside service to insert, retrieve, move and store the SBA. Multiple SBA'"'"'s could be used in buses, trucks, vans, agricultural and construction vehicles and boats. The geometry, configuration, electric and electronic connectors, voltage, communication interface and protocol of the SBAs in the system should be made following standard specification for assured interchangeability. SBA shall have the option to have builtin charge controller and inverter, thus with both AC and DC connectors that match those on the BC. Extra SBAs could be used as online, offline energy storage means with centralized or decentralized recharge/discharge abilities and serving for emergency power supply means.

4. Battery Compartment (BC) as set forth in claim 1, is a box shaped device installed on the EV and RS, designed to contain, store, hold and connect the Discharge/Recharge electric poles (separate DC and AC poles) and communication ports on the SBA with those on the EV or RS. The. BC has powered or unpowered rollers/rail for facilitating insertion or retrieval of the heavy SBA to and from BC by either robotic mechanism or manual means;

the elastomer lined rollers also serve as damping device to buffer road vibration. The BC has locking mechanism to ensure the correct and secure seating position of SBA and dependable connection of all the electric and electronic interface between SBA and EV, or SBS and RS, the locking mechanism may include sensors to signal the conveyor robotic system, the driver and the RS for final adjustment, and for signaling correct or erratic seating conditions.

5. A RS subsystem as set forth in claim 1, comprises of a multitude of RS stations distributed in the entire service territory (local, national and international) to provide SBA swapping, recharge, service, management and billing services. A RS has a multitude of battery swapping ports leading from the entrance driveway from a street. Each battery swapping port is equipped with a movable reception ramp with powered or nonpowered rollers to aim to the exit door of the BC on the EV. RS also is equipped with 3D stack of BCs with manual, semiautomatic or automatic transport/stacking means to move SBAs to and from the BC of the EVs from and to the computer designated BC slot address in the 3D stack. The BCs in the RS have the receptacles and ports for electric and electronic connection to the stored SBA, and positioning and locking mechanism and signal sensors, similar to those in the BC of the EV, to assure dependable physical, electric and electronic positioning and connections between the SBA and BC. The RS computer should retrieve and monitor the data on all the SBAs in the BC slots to determine the suitable recharge, maintenance processes and status, the readiness to be inserted to a customer EV, or to be discarded and replaced. The data exchange between the SBA and RS should include but not limited to the date and time stamps, the IDs of the EV and SBAs being served, the technical condition and discharge/recharge history of the SBA, the energy left in the SBA, the recharge process, etc. for billing, maintenance, and management purposes. The RS will be supplied with recharge electricity by the electric power network or distributed power generation facilities and serving as part of the smart network—

a district bank of electricity depository to buffer the network loading fluctuation by feeding back some energy back to the network, or in emergency, when needed.

6. Computerized Management Subsystem (CMS) as set forth in claim 1, includes software and hardware, for finance, billing and management functions, that connects all the computers in the RS and those in the headquarters of the EV-SESS with high speed IT connection network.

The CMS is equivalent to the central nervous system in a highly functioning organism—

an indispensable subsystem of the entire EV-SESS. The computers in each of the RS have interfacing/communication capabilities with the EVs at the service ports and the SBAs in the BCs at the BC stacks and the SBA stacking/transportation carriers.
