Description

Motorized Trailer with Swappable Batteries Description Technical Field This invention pertains to trucking or general trailer pulling where the trailer has electrically driven wheels. This invention improves and repurposes the motorized trailer with swappable batteries. The advantage of this invention is to add range to electric towing vehicles by offsetting a large portion of motive power needs and is advantaged by carrying the weight of batteries needed for long range which at present is significant. In another context, fuel use and associated Greenhouse Gas (GHG) emissions, can be substantially reduced by employing the combined energy and motive power of the invention instead of fuel utilized by the towing vehicle's engine.
A further feature of this invention is to enable exchange of long-range, heavy batteries with shorter range, lighter batteries which bring advantage in stop and go city traffic by regenerative braking. This means that more power is available to accelerate and decelerate the laden trailer vehicle. In the context of a Diesel or otherwise fuelled vehicle, it means that regenerative braking can be used where no such feature exists in the towing vehicle, saving fuel.
An optional feature of this invention is that by virtue of adding a large rack to the sides of the trailer to hold a long-range capable set of batteries, in particular for a semi-trailer, an aerodynamic drag reducing skirt can be integrated in the design. If made sturdy enough, this skirt can also act as a side-impact or under-run barrier, further improving safety.
Background Art There is a patent for a battery-driven motorized trailer U.S. Patent Number 7,147,070 There are examples of motorized trailers with plug-in rechargeable batteries (DE102012011960) Electric Vehicles with battery swapping schemes U.S. Patent Number 8,146,694.

None of these prior patents suggest advantage of battery swapping in a trailer, but having swappable batteries in the trailer improves on previous schemes. It allows large battery assets to be in constant use and smaller batteries for regenerative purposes or empty batteries during disuse. It allows compatibility across vehicle types using a common format. It also makes swapping potentially simpler by exchanging batteries from the side instead of from below as is needed to preserve vehicle aesthetics because trailers tend to be utilitarian in nature. It enables a quick transition to renewable energy without dumping assets or waiting for their end of life by retrofitting existing trailers.
Summary of Invention The invention is a motorized trailer with a battery rack or other means of battery exchange which allows swapping or replacement of batteries. A trailer control module gets signals from the towing vehicle to command force applied to the trailer wheels to a great extent replace energy needed from the towing vehicle, displacing the fuel and GHG emissions normally associated with towing vehicle operation or extending range in the case of a towing EV. The trailer's extra motive force helps compensate for the added battery mass. The swappable batteries can be of at least 3 types, but of the same physical form: a long range, heavy battery, a short range, lightweight battery generally for city use, and a dummy battery used for extended trailer disuse. Added aerodynamic advantage and safety is gained when the battery rack or holder can double as an aerodynamic improving skirt and side-impact or under-run protection.
Brief Description of Drawings FIG. 1 is a schematic side elevation view of a semi tractor trailer rig with battery modules, racks, hub motors; motor driver, sending unit and control module.
FIG. 2 is a schematic plan view of a semi tractor trailer rig with battery modules, racks, hub motors;
motor driver, sending unit and control module; and battery interface module.
2 Description of Embodiments Examplel With reference to FIGS 1 and 2: In the preferred embodiment of the invention, a semi trailer 9 is retrofitted or has integrated a rack 2 with battery modules 1. This rack allows battery modules 1 to be removed from the side as is found in prior art U.S. Patent Number 8,146,694 or in other art. A sending unit 5 interfaces with the semi-tractor 8 computer to acquire information such as accelerator pedal position and transmission gear. The sending unit 5 communicates with the control module 3.
The battery module 1 has its own battery management system and a communication interface which connects to the battery interface module 6 with power connectors. The battery module 1 has a specific form factor so that different types of battery modules of varying capacity and chemistry, including empty battery modules 1, can be swapped in. This allows optimum configuration based on needs whether long range, short-range regenerative or parked for long periods of time. A mix of battery module 1 types is also possible. Battery module 1 are typically rechargeable.
The battery interface module 6 has connectors for power and communication to each of the battery modules 1 in the rack 2. This battery interface module connects via wires, the power interface of the battery modules 1 to the motor driver module 4. The communication interface is connected to the trailer control module 3 which includes a computer that is tasked with managing via communication wires to the motor driver, power applied to the (hub) motors 7, or power from the (hub) motor 7 in regenerative mode. The battery interface module 6 also has means to retain each battery module 1 in position, via an electric latch for example.
Attached and connected to the tractor 8, the tractor sending unit 5 sends tractor 8 state information such as accelerator pedal position, current speed, current gear selected, and other information to the the trailer control module 3. The trailer control module 3 using signals from the tractor sending unit 5, internal sensors, notably an accelerometer, and from trailer 9 sensors such as pressure to the brakes, wheel rotation sensors and tail light signals determines the best power level and mode the motor driver must deliver. These signals are used to determine desired push or pull from driver input, to detect wheel slip, engage motor overdrive hill mode when the accelerometer indicates a grade, disengage when necessary etc...
3 In the preferred embodiment an optional aerodynamic skirt is attached to the rack 2 which reduces drag and improves tractor-trailer rig 8 and 9 efficiency. The rack 2 is also built to a standard so as to act as a side impact guard.
The trailer control is optionally fitted with short range encrypted wireless communication which allows low speed engagement of the motor under supervisory control. The tractor 8 transmission must be set to neutral and the parking brake disengaged as minimal conditions.
A plug for battery charging can be provided to recharge the batteries in-situ.
This feature would interface with the motor driver module 4 and trailer control module 3. A
rooftop solar panel array can aid in energy maintenance if desirable and would be added as solar connector on the motor driver module 4. =
The battery modules 1 can also be used to power a reefer refrigeration system and allows battery swap from a supply truck in a similar manner reefers are refuelled while maintaining refrigeration levels.
This could be a connector on the motor driver module 4.
The control module 3 can select power transfer to specific batteries allowing a specific battery module 1 to be charged or discharged so that a supply truck only need replace selected battery modules 1.
A mode can be triggered in the control module 3 when EV tractor 8 battery levels are low as signalled by the tractor sending unit 5, where regenerative braking is disengaged allowing the EV tractor 8 to be recharged by regenerative braking. Alternatively, direct connection to a towing EV can transfer power.
Extra space in the racks 2 can be used for extended trips, especially in a 53' version of the trailer 9 and this extra space can be used for redistribution of battery modules 1.
Redistribution can be part of trips for other purposes avoiding the need for dedicated redistribution.
Example2 A second notable embodiment is where the tractor 8 is a car or truck and the trailer 9 is a utility, van or camper trailer. In this case an optional utility plug can be provided or power to the trailer can be provided even when not connected to the tow vehicle or plugged in, essentially a backup power supply.
The battery modules can be compatible with the semi-trailer 9 battery modules 1 which would help kick-start the needed infrastructure of battery module swap stations.
4 Industrial Applicability In combination with battery swap stations, optimally situated along highways, battery swap motorized trailers provide electric energy for any journey length, with short battery swap breaks every 4 or 5 hours, even longer durations are possible with higher energy density batteries or longer 53' trailer instead of the 40' trailer illustrated. Battery module configuration can be optimized to expected journey conditions.
