Hybrid/EV Battery Section 1 and Hybrid/EV Battery Section 2

The hybrid/EV battery section 1 and hybrid/EV battery section 2 are a pair of lithium-ion batteries connected in series to make up the 115 V DC battery. The two sections are diagnosed and serviced as a single battery assembly. The individual battery sections are not serviced separately.

The hybrid battery contains a total of 32 cell groups, with each section containing 16 cells that are connected in series using internal bus bars. The two battery sections are externally connected in series using high voltage cable. Each individual cell group is rated at 3.7 V, for a nominal system voltage of 118 V DC.

The hybrid battery sections are air cooled. Each battery case has an air inlet and an air outlet. Air is drawn through the battery case to cool the individual cells. Attached to each case is a vent tube. In the event of a damaged or ruptured battery, any outgassing will be vented to the outside of the vehicle.

A voltage sense circuit is attached to each individual cell. Each of these circuits terminate at a connector located on the top surface of the battery section. A serviceable auxiliary battery wiring harness connects the voltage sense circuits to the battery energy control module, located directly above the battery sections. The sensor itself is a part of the battery cell and is not serviceable.
