chevy bolt battery dimensions

The gravimetric energy density or specific energy (kWh/kg) is better than the Model S P85 pack.

The Chevrolet Bolt or Chevrolet Bolt EV is a front-motor, five-door all-electric subcompact hatchback marketed by Chevrolet; developed and manufactured in partnership with LG Corporation.

These probably serve the dual purpose of electrical isolation and fire resistance. The BMS controller is mounted inside the pack enclosure on top and at the rear. The whole battery configuration is also flat and packed tight - a first for GM (see photo below).A Chevrolet Bolt EV battery pack, far right, is compared to battery packs from, left to right, a first generation Volt, a second generation Volt, and a Spark EV in General Motors Global Battery Systems Laboratory at the GM Technical Center in Warren, Michigan, Tuesday, April 5, 2016.

The modules are sealed in a metal box.

The pack consists of ten modules, two in a row.

Tesla has recently announced it has been It’s worthwhile to note that in some ways, the distinction between NCA and NCM may be blurred because of the blending of materials. Inside, each module is encased in plastic enclosures with mechanical connections to the outer box.

The vertical plates help carry heat from the core of the pack to the base.The design was optimized for even temperature across the pack.The pack has a stacked module arrangement at the rear. The pack is center tapped. The pack construction, design, and cooling use distinctly different approaches, and the cell chemistries differ.Both packs are sealed with entry points for liquid coolant and electrical connections. High-voltage electronics are completely enclosed in a package above and attached to the battery pack. The Bolt sources its pouch type cells from LG Chem, while the Tesla Model 3 uses cylindrical cells sourced from Panasonic.

Each module is about 235 lb.

Munro was particularly impressed with the cell matching, down to 0.2 mV. InsideEVs: France It is common for EVs to have a center pack disconnect and fuse.
