Trailer mounted battery range extender for electric truck tractor
View Patent ↗A tractor trailer battery system having a battery compartment containing one or more battery units which house one or more battery cells, electrical leads from the battery units to a trailer mounted controller in electrical communication with a cab mounted controller which is in electrical communication an electric motor or hybrid engine system. The battery system allows for either the trailer mounted controller or the cab mounted controller to provide principal communication to the electric motor or hybrid engine system.
1. A battery range extender system for a hybrid or electric tractor-trailer having a hybrid or electric motor housing a tractor battery, said tractor-trailer having a tractor and a trailer, said trailer having a front end and a rear end, said battery range extender system comprising:
a battery compartment positioned beneath said trailer;
said battery compartment defined by a first side and an opposing second side;
at least one door in communication with at least one of said first side and said opposing second side;
at least one battery cell in removable communication with said battery compartment and in electrical communication with said motor; wherein said at least one battery cell may be removed from said compartment for one of recharging or replacement of said at least one battery cell;
at least one battery charging port electrically coupled with said battery cell, wherein said at least one battery charging port is located at a location selected from the group consisting of said trailer rear end, said trailer front end and said tractor; and
said at least one battery cell electrically coupled with said tractor,
wherein said at least one battery cell is chargeable at the same rate as the tractor battery.
2. The range extender system of claim 1 further comprising, said at least one cell having at least one guide channel.
3. The range extender system of claim 2 further comprising, said at least one guide channel positioned between a cell first side and a cell second side, wherein said at least one guide channel provides for said at least one cell alignment in said compartment.
4. The range extender system of claim 1 further comprising, said at least one cell having at least one electrical connection provided at least in close proximity to a surface of said at least one cell.
5. The range extender of claim 4 further comprising, said at least one electrical connection electrically coupled with a trailer connection.
6. The range extender of claim 1 further comprising said at least one cell having an attachment assembly, said attachment assembly being coupled to a cell first side and wherein said at least one cell may be removed from said compartment.
7. The range extender of claim 6 further comprising, said attachment assembly having at least one of a rod, a hook and a ring.
8. The range extender of claim 1 wherein, said at least one door is pivotally attached to at least one of said first side and said oppositely opposed second side.
9. The range extender of claim 1 further comprising, at least one locking mechanism in close proximity to at least one of said at least one door and said compartment, providing releasable communication with said at least one cell.
10. The range extender of claim 1 further comprising, said at least one cell electrically coupled to at least one of an electric motor and a hybrid engine.
11. The range extender of claim 10 further comprising a first charging port and a first controller electrically coupled to at least one of said electric motor, said hybrid engine and said at least one cell.
12. The range extender of claim 10 further comprising a second charging port and a second controller positioned in close proximity to a back of said trailer.
