Embodiments of the present disclosure generally relate to the field of powered vehicles. More specifically, embodiments of the disclosure relate to an apparatus and methods for a mobile charging station for recharging multiple electric vehicles.
Electrically powered vehicles generally solve problems associated with gasoline-powered vehicles, such as environmental pollution, noise and depletion of crude oil reserves due to the increasing use of gasoline-powered vehicles. As such, electrically powered vehicles are gaining in popularity and their use is becoming increasingly widespread. Unfortunately, a fast-charge infrastructure is failing to meet the increasing demands posed by an ever-increasing number of electric vehicles on the roads. For example, establishing a stationary fast-charging station tends to be a lengthy process. In many instances, acquiring the necessary permits to start construction of a fast-charging site can take up to two years.
Given the increasing prevalence of electric vehicles of all types, there is a continuing interest in providing a fast-charging infrastructure that is capable of meeting the demands of a growing national fleet of electrically powered vehicles.
An apparatus and methods are provided for a mobile charging station for simultaneously charging multiple electrically powered vehicles. The mobile charging station comprises a trailer housing rechargeable batteries and multiple fast-charge ports disposed on the trailer for servicing the electrically powered vehicles. The mobile charging station can be coupled to a truck and moved to any suitable location for charging the electrically powered vehicles. The onboard rechargeable batteries can be recharged with electrical energy from an electrical grid, a solar array, or by way of equipment stored onboard the trailer. Each fast-charge port includes a charging cable for routing electricity to an electrically powered vehicle to be recharged. A connector comprising each charging cable is configured to be plugged into a charging port of the electrically powered vehicle. Each charging cable is supported by an elastic cable mounted to the trailer above the charge port.

These and other features of the concepts provided herein may be better understood with reference to the drawings, description, and appended claims.
The drawings refer to embodiments of the present disclosure in which:
While the present disclosure is subject to various modifications and alternative forms, specific embodiments thereof have been shown by way of example in the drawings and will herein be described in detail. The present disclosure should be understood to not be limited to the particular forms disclosed, but on the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the present disclosure.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure. It will be apparent, however, to one of ordinary skill in the art that the mobile charging station and methods disclosed herein may be practiced without these specific details. In other instances, specific numeric references such as “first charger,” may be made. However, the specific numeric reference should not be interpreted as a literal sequential order but rather interpreted that the “first charger” is different than a “second charger.” Thus, the specific details set forth are merely exemplary. The specific details may be varied from and still be contemplated to be within the spirit and scope of the present disclosure. The term “coupled” is defined as meaning connected either directly to the component or indirectly to the component through another component. Further, as used herein, the terms “about,” “approximately,” or “substantially” for any numerical values or ranges indicate a suitable dimensional tolerance that allows the part or collection of components to function for its intended purpose as described herein.
Electrically powered vehicles generally solve problems associated with gasoline-powered vehicles, such as environmental pollution, noise and depletion of crude oil reserves due to the increasing use of gasoline-powered vehicles. As such, electrically powered vehicles are gaining in popularity and their use is becoming increasingly widespread. Unfortunately, a fast-charge infrastructure is failing to meet the increasing demands posed by an ever-increasing number of electric vehicles on the roads. Given the increasing prevalence of electric vehicles of all types, there is a continuing interest in providing a fast-charging infrastructure that is capable of meeting the demands of a growing national fleet of electrically powered vehicles. Embodiments disclosed herein relate to a mobile charging station that can be implemented more quickly than stationary charging stations that require a lengthy permitting process.
The mobile charging station 100 generally comprises a trailer 108 that houses a multiplicity of rechargeable batteries (not shown) for charging the vehicles 104. As such, the trailer 108 can be coupled with a truck and then moved to any suitable location for charging the vehicles 104. In some embodiments, multiple trailers 108 may be parked together at the same site and combined to provide a portable fast-charging station capable of servicing large numbers of vehicles 104, as needed. It is contemplated that such a portable fast-charging station may comprise an electric analog of a traditional service station that provides gasoline and diesel to internal combustion fueled vehicles. As such, each of the vehicles 104 may be charged for the quantity of electric charge received from the mobile charging station 100. Further, the portability of the trailer 108 facilitates leasing the mobile charging station 100 to third party vendors, as desired.
Moreover, the portability of the mobile charging station 100 provides an additional benefit of obviating any need for a permitting process that is typically required before beginning construction of a new stationary fast-charging station. As such, it is envisioned that the mobile charging station 100 can be implemented to provide a fast-charging infrastructure that is capable of meeting the demands of a growing national fleet of electrically powered vehicles.
In one exemplary embodiment, the trailer 108 comprises a 19-foot long truck trailer that is configured to service five electrically powered vehicles, such as the vehicles 104. In such a five port system, the trailer 108 may house about 2,500 or more lead-acid batteries for charging the vehicles 104. As indicated in
As shown in
As will be appreciated, fast-charging systems capable of providing 220 Volts require relatively heavy charging cables 124. Thus, each charge port 120 may include an elastic cable (not shown) that supports at least a portion of the weight of the charging cable 124. It is contemplated that the elastic cable may be coupled with a mount or a mechanism disposed on the trailer 108 above each fast-charge port 120. It is further contemplated that each fast-charge port 120 may include LEDs that are configured to display information pertaining to charging the vehicle 104, such as charging rate, charge status of the battery of the vehicle 104, total charge transferred to the battery of the vehicle 104, total cost of transferred charge, and the like, without limitation.
While the mobile charging station and methods have been described in terms of particular variations and illustrative FIGURES, those of ordinary skill in the art will recognize that the mobile charging station is not limited to the variations or FIGURES described. In addition, where methods and steps described above indicate certain events occurring in certain order, those of ordinary skill in the art will recognize that the ordering of certain steps may be modified and that such modifications are in accordance with the variations of the mobile charging station. Additionally, certain of the steps may be performed concurrently in a parallel process when possible, as well as performed sequentially as described above. To the extent there are variations of the mobile charging station, which are within the spirit of the disclosure or equivalent to the mobile charging station found in the claims, it is the intent that this patent will cover those variations as well. Therefore, the present disclosure is to be understood as not limited by the specific embodiments described herein, but only by scope of the appended claims.
