The Chevy Volt relies on a dedicated high‑voltage battery to power its electric drive. This article explains the battery type and how it differed between generations.
A Chevy Volt uses a high‑voltage lithium‑ion battery pack for propulsion. The first‑generation Volt (2011–2015) used a 16 kWh pack, while the second‑generation Volt (2016–2019) uses an 18.4 kWh pack. Both packs are supplied by LG Chem and mounted behind the rear seats, with a separate 12‑volt battery handling house‑hold electronics and safety systems.
Battery specifications by generation
Below is a generation‑by‑generation look at the Volt’s main energy storage, highlighting size, layout, and supplier details.
First generation (2011–2015)
Before listing the specifics, the aim is to describe how the early Volt stored and used electricity for driving.
- Battery type: Lithium‑ion (Li‑ion) energy storage for propulsion
- Nominal capacity: 16 kWh
- Location and packaging: Modular pack mounted behind the rear seats with active cooling
- Cell supplier: LG Chem
Concluding for the first generation: The 16 kWh pack established the Volt’s electric‑drive capability and helped define its all‑electric range during its early years.
Second generation (2016–2019)
Before listing the specifics, the aim is to outline how the larger pack changed the vehicle’s electric driving profile.
- Battery type: Lithium‑ion (Li‑ion) energy storage for propulsion
- Nominal capacity: 18.4 kWh
- Location and packaging: Similar layout behind the rear seats with updated cooling and packaging
- Cell supplier: LG Chem
Concluding for the second generation: The 18.4 kWh pack increased potential all‑electric driving and extended the Volt’s electric‑only capability while preserving the familiar design and installation.
Charging and auxiliary systems
This section highlights how the Volt’s main battery is charged and how it relates to the vehicle’s other electrical systems.
- Charging options: Level 1 (120V) and Level 2 (240V) charging via the onboard charger
- Main vs. auxiliary battery: The high‑voltage pack powers the electric drive; a separate 12‑volt battery handles accessories and control systems
- Maintenance and guidance: Use GM‑approved components and follow official service guidelines for battery replacement or diagnostics
Concluding note: Charging is compatible with typical home or public charging setups, and proper maintenance is essential for longevity and safety.
Summary
The Volt’s propulsion relies on a lithium‑ion high‑voltage battery pack, with generation‑two packs at 18.4 kWh and generation‑one packs at 16 kWh. Both were supplied by LG Chem and located behind the rear seats, complemented by a 12‑volt auxiliary battery. Production ran from 2010 to 2019, after which GM shifted focus to broader electrification strategies.
