The Honda Clarity uses lithium-ion battery packs across its three variants. The BEV version carries a 35.5 kWh pack, the PHEV uses about a 17 kWh pack, and the Fuel Cell variant relies on a small lithium-ion battery to support the fuel-cell system.
Beyond the battery size, the Clarity family relies on lithium-ion energy storage for all versions, with capacities and roles that differ by powertrain. The BEV and PHEV depend primarily on their battery packs for propulsion, while the FCEV uses a compact Li-ion pack to supplement the hydrogen fuel-cell stack and vehicle electronics. Battery chemistry is consistent with standard Li-ion technology used across many modern electric-drive vehicles.
Battery technology across the Clarity lineup
Overview of the battery technology and capacity across the three models:
- Clarity Electric (BEV): Lithium-ion battery pack, about 35.5 kWh capacity, enabling roughly 89 miles of EPA-estimated range in early models.
- Clarity Plug-in Hybrid (PHEV): Lithium-ion battery pack, about 17 kWh capacity (roughly 13–14 kWh usable), enabling about 47 miles of all-electric range with a total range around 300–340 miles depending on year and conditions.
- Clarity Fuel Cell (FCEV): Uses a hydrogen fuel-cell stack with a small lithium-ion battery pack to support systems; the specific capacity is not widely published by Honda, and the battery is much smaller than BEV/PHEV packs.
In all cases, the battery technology is lithium-ion, aligned with industry norms for energy storage in modern EVs. Availability of each Clarity variant has varied by market and model year, and Honda has curtailed wide-sale Clarity production in the U.S. in recent years.
Variant notes and considerations
BeV vs PHEV vs FCEV in practice
The BEV relies entirely on its battery for propulsion between charges. The PHEV uses a larger gasoline engine as a back-up once the battery is depleted, while the FCEV runs on hydrogen and uses the battery primarily to smooth power delivery and assist operations such as start/stop and regenerative braking.
Prospective buyers should consider daily driving distance, charging or hydrogen-access availability, and regional availability, since the Clarity lineup has seen limited deployment in some markets and shifts in focus in recent years.
Summary
The Honda Clarity family uses lithium-ion battery packs. The Electric variant uses about 35.5 kWh, the Plug-in Hybrid about 17 kWh, and the Fuel Cell variant relies on a small Li-ion pack to support its hydrogen-powered system. This reflects common industry practice for Li-ion energy storage, with each variant tuned to its respective powertrain. For current purchasing options and availability, note that Clarity variants have had limited availability in many markets as Honda re-evaluated the model lineup in recent years.
