System for high density testing of batteries within an environmental test chamber
The All Test Platform (ATP) provides provides a safe and easy way to test batteries within an environmental test chamber. The ATP enables rapid changing of batteries and battery types between tests, and provides the highest density per square foot of environmental test chamber space available for battery testing. The ATP combines multiple components critical for battery testing into a configurable, scalable, safe, and high density battery testing platform.
1. A battery test platform system for insertion into an environmental test chamber and connection to an external system powering and monitoring batteries during test, the system comprising:
a frame having two side walls, a bottom wall, and a side wall gap in one of the side walls allowing environmental conditions from the environmental test chamber to flow properly through the battery test platform system;
two or more frame rails attached to the side walls;
one or more carriers, each carrier connecting to two frame rails to slide in and out of the frame;
one or more non-conductive shelves inserted into each carrier;
one or more flexible cable carriers, positioned with one flexible cable carrier under each shelf, wherein each flexible cable carrier is a chained track such that a flex region of the chained track changes as the carrier is slid in or out of the frame, maintaining wiring positions of any wiring guided through the track;
one or more battery interface boards (ABIBs) inserted one per carrier between the two non-conductive shelves in each carrier; and
wiring guided through each of the flexible cable carriers such that each flexible cable carrier guides a wiring bundle connected from one end of the ABIB on the carrier above the flexible cable carrier to exiting the battery test platform system, and wherein the wiring provides a Force+, a Force−, a Sense+, and a Sense− connection per battery under test on the shelf above the flexible cable carrier;
wherein each ABIB is swappable to change the type of battery being tested.
2. A battery test platform system for insertion into an environmental test chamber and connection to an external system powering and monitoring batteries during test, the system comprising:
a frame having two side walls and a bottom wall;
two or more frame rails attached to the side walls;
one or more carriers connecting to the frame rails;
one or more non-conductive shelves inserted into each carrier;
one or more flexible cable carriers, positioned with one flexible cable carrier under each shelf;
one or more battery interface boards (ABIBs) inserted one per carrier; and
wiring guided through at least one of the flexible cable carriers, wherein the wiring connects to an ABIB in the carrier above the flexible cable carrier to provide a Force+, a Force−, a Sense+, and a Sense− connection per battery under test on the shelf above the flexible cable carrier.
3. The system of claim 2 , wherein the one or more carriers further comprises four carriers.
4. The system of claim 2 , wherein the one or more non-conductive shelves further comprise two non-conductive shelves per carrier.
5. The system of claim 2 , wherein the frame further comprises a side wall gap in one of the side walls, allowing environmental conditions from the environmental test chamber into the test platform system.
6. The system of claim 2 , wherein each non-conductive shelf is made of FR4 glass epoxy.
7. The system of claim 2 , wherein each non-conductive shelf is made of aluminum and ionized to be non-conductive.
8. The system of claim 2 , wherein each non-conductive shelf further comprises a shelf having four hundred and sixty holes, each hole having a diameter of three hundred and seventy millimeters.
9. The system of claim 2 , wherein each non-conductive shelf has a flatness tolerance such that a surface of the shelf has a flatness with an overall maximum deviation of 1 millimeter and a maximum deviation of 0.25 millimeter across any 100 square millimeter region within the surface.
10. The system of claim 2 , wherein each flexible cable carrier is a chained track supporting wiring from one end of an ABIB in the carrier above the flexible cable carrier to exiting the battery test platform system.
11. The system of claim 10 , wherein the chained track adjusts a flex region as the carrier above is slid in or out of the frame, thereby maintaining wiring connections of wiring routed through the chained track.
12. The system of claim 2 , further comprising sixty-four batteries connected eight per shelf, and sixteen per carrier, through the one or more ABIBs to the external system.
13. The system of claim 2 , wherein each of the one or more ABIBs is specific to a type of battery being tested, and is swappable to change the type of battery being tested.
14. The system of claim 13 , wherein each of the one or more ABIBs includes one of the following: spring-loaded terminal clips for connection to cell batteries; coin cell connectors for connection to coin cell batteries; cylindrical cell battery holders with connectors for connection to AAA, AA, C, D, 18650, or 21700 batteries; and connectors for flex cable connectors to connect to pack batteries.
