What type of battery is in a Chevy Bolt?
The Chevy Bolt uses a lithium-ion battery pack with nickel manganese cobalt oxide (NMC) chemistry, built by LG Energy Solution. The pack size has evolved from about 60 kWh in earlier models to roughly 65 kWh gross in newer versions, with around 60 kWh usable energy. It is a high-voltage traction battery, not a conventional 12-volt or lead-acid pack.
Battery chemistry and supplier
The following details explain the components and design choices behind the Bolt's high-voltage battery.
- Chemistry: Lithium-ion cells using nickel manganese cobalt oxide (NMC) chemistry.
- Cell format: The pack uses pouch-style cells assembled into a modular battery block.
- Supplier and integration: LG Energy Solution (formerly LG Chem) provides the cells, while GM completes pack assembly and integration into the vehicle chassis.
- High-voltage system: The battery operates in the roughly 350–400-volt range, powering the electric drive.
- Capacity variations by generation: Early Bolts used about a 60 kWh usable energy pack, while later Bolts adopted a ~65 kWh gross pack with around 60 kWh usable energy.
- Thermal management: The pack is cooled by a dedicated liquid cooling loop to manage temperature during charging and driving.
These points summarize the general battery setup for the Bolt family and how it has evolved over time.
Year-by-year capacity and model variations
With the 2022 refresh, Chevrolet updated the battery to a larger gross capacity while maintaining practical usable energy for daily driving. The Bolt EUV shares the same high-energy pack but is tuned for a different aerodynamic and weight profile, affecting range.
- 2017–2021 Bolt EV: roughly a 60 kWh usable capacity pack, delivering about 238 miles of EPA-rated range in most trims.
- 2022–2023 Bolt BEV: about a 65 kWh gross pack, with around 60 kWh usable energy and EPA ranges near 259 miles for the Bolt BEV; the EUV variant typically shows slightly lower EPA range due to its size and weight.
- Bolt EUV (2021–present): uses the same 65 kWh gross pack but with different aerodynamics and weight, resulting in a somewhat lower EPA range (generally in the mid-240s miles).
These year-by-year details show how GM adjusted the battery sizing and range during the Bolt's production run, while preserving the same general chemistry and supplier setup.
Summary
In short, the Chevy Bolt uses a high-voltage lithium-ion battery pack with NMC chemistry supplied by LG Energy Solution. Early models used about a 60 kWh usable pack, while newer versions use a 65 kWh gross pack (roughly 60 kWh usable). The pack is liquid-cooled, integrated into the vehicle’s underbody, and designed to deliver the Bolt’s electric range and performance across model years.
Does GM use LFP batteries?
GM Confirms LFP Batteries, Marking Shift in EV Strategy. General Motors will begin LFP battery production at its Spring Hill, TN, plant, somewhat shifting its battery strategy to lower-cost cells.
What type of battery does a Chevy Bolt have?
Chevrolet Bolt/Bolt EUV - Lithium 12V Battery.
What is the battery problem with the Chevy Bolt EV?
GM announced in August of this year that all Chevy Bolts, from 2017-2022, have been recalled due to a fire problem when their batteries were fully or almost nearly charged. The Bolt is an all-electric vehicle that was launched in 2017.
Does the Chevy Bolt have an LFP battery?
The 2027 Chevy Bolt is equipped with a 65kWh LFP battery with 255 mile range and a charging speed of 10%-80% in 25 minutes at 150kW on a DCFC (NACS charging port).
