| 20090082957 | Electric Vehicle Network - An electric vehicle that includes an electric motor that drives one or more wheels of the vehicle and is powered by a battery. The electric vehicle determines a status of a battery of the vehicle and a geographic location of the vehicle. The electric vehicle then identifies at least one battery service station that the vehicle can reach based on the charge status of the battery of the vehicle and the geographic location of the vehicle. The electric vehicle displays the at least one battery service station to a user of the vehicle. | 03-26-2009 |
| 20100094496 | System and Method for Operating an Electric Vehicle - A system and method for managing energy usage in an electric vehicle. A charge level of at least one battery of the electric vehicle is received. A current location of the electric vehicle is received. A theoretical maximum range of the electric vehicle is determined based on the current location of the electric vehicle and the charge level of the at least one battery of the electric vehicle. An energy plan for the electric vehicle is generated | 04-15-2010 |
| 20100112843 | System for Electrically Connecting Batteries to Electric Vehicles - The connection system is designed to facilitate electrical and data connections between the battery and the electric vehicle. The connectors are designed with alignment mechanisms to account for initial misalignment of the battery and vehicle while still ensuring positive contact between them. The alignment mechanisms also introduce compliance into the system to ensure that the mechanical components of the system are not placed under unwanted loads or stresses. The connection system houses data connectors carrying communication signals as well as power connectors carrying high voltage electricity. The data connectors are shielded to prevent interference caused by proximity to the high voltage elements. The connection system uses no mechanical latching or locking mechanisms. | 05-06-2010 |
| 20100141206 | Battery Exchange Station - At a battery exchange station a discharged battery is removed and a charged battery is inserted into an electric vehicle. The battery exchange station has various mechanisms to make this exchange. In some embodiments, the batteries are stored in a warehouse, where they are given an appropriate amount of charge. The charged batteries are moved from the warehouse by an automated robotic mechanism. The automated robotic system provides the charged battery to a battery exchange system which inserts the charged battery into the vehicle after it removes the discharged battery from the vehicle. The insertion and removal of the battery is done vertically, i.e., into and out of the bottom of the vehicle. The battery exchange system is located in a service bay under the vehicle. A sliding door system creates an opening above the service bay. The opening is of variable size depending on the size of the vehicle. | 06-10-2010 |
| 20110044791 | Battery Exchange Station - At the battery exchange station a discharged battery is removed and a charged battery is inserted into an electric vehicle. The battery is inserted and removed along a vertical axis, i.e., into and out of the bottom of the vehicle. The battery exchange system is located in a service bay under the vehicle. A sliding door system creates an opening above the service bay. A vehicle is received over the sliding door system, such that at least one wheel of the vehicle rests on the conveyor system. The door slides in a first direction while allowing the conveyor system to slide in a direction opposite the first direction. The conveyor system also supports the at least one wheel of the vehicle while the door and conveyor slide in opposite directions. The sliding of the door and the sliding of the conveyor system occur at least partially simultaneously. | 02-24-2011 |
| 20110071932 | Electric Vehicle Network - An electric vehicle network is provided. The electric vehicle network includes a plurality of battery service stations and a service provider. The battery service stations are configured to service the batteries of a plurality of electric vehicles, and the electric vehicles are operated by a plurality of users. Battery service stations are configured to recharge batteries, replace spent batteries, or both. The service provider communicates with the battery service stations to facilitate servicing of the electric vehicles as the service stations based on subscription plans associated with the users. A plurality of subscription plan options is provided to the users. | 03-24-2011 |
