Method and apparatus for identifying battery pack types
First Claim
1. A vehicle comprising:
- (i) a battery pack comprising;
battery cells;
battery cell sensors, each of the battery cell sensors corresponding to and in communication with one of the battery cells, to;
measure attributes of each of the battery cells; and
generate battery cell sensor signals for each of the battery cells based on the measured attributes;
connecting wires, each connecting wire being in communication with (a) one or more of the battery cells, or (b) one or more of the battery cell sensors to transmit the battery cell sensor signals; and
a connection module comprising a plurality of active connection module pins, each of the active connection module pins being in electrical communication with at least one of the plurality of connecting wires;
(ii) a port configured to interface with the connection module, the port comprising a plurality of port pins configured to respectively engage with the plurality of active connection module pins and thereby receive the battery cell sensor signals from the connecting wires via the port pins; and
(iii) processor(s) configured to;
receive the battery cell sensor signals via the port pins;
determine an arrangement of the active connection module pins based on the battery cell sensor signals;
load a database that relates arrangements of active connection module pins to battery pack identification information;
determine, by looking up the determined arrangement of the active connection module pins in the database, identification information corresponding to the battery pack;
select an operational strategy for the vehicle based on the determined identification information of the battery pack; and
implement the selected operational strategy on the vehicle.

Abstract
A method, apparatus, and system are disclosed for analyzing a vehicle battery system of a hybrid or electric vehicle that includes a battery pack and a battery controller. More specifically, a battery controller is disclosed for determining battery identification information of the battery pack based on a configuration of active and non-active pins in a connection module between the battery pack and the battery controller. It follows that the battery controller may identify the battery pack type in an efficient manner that does not require any additional components. The battery controller may further reference the battery identification to implement a battery operational strategy that may better realize an efficiency or durability of the identified battery.
