The IONIQ 5 uses high-energy-density lithium-ion battery packs with nickel-manganese-cobalt oxide (NMC) cathodes, available in two sizes—58 kWh and 72.6 kWh—with an 800-volt architecture designed for rapid charging.
This article explains the battery chemistry, capacity options, charging capabilities, and who supplies and integrates the packs within Hyundai’s E-GMP platform, helping you understand how the IONIQ 5 stores and delivers its energy.
Battery chemistry and architecture
The IONIQ 5’s energy storage is built around Hyundai’s Electric Global Modular Platform (E-GMP). The packs use NMC chemistry and are designed for an 800-volt electrical architecture that enables ultra-fast charging and high efficiency, while remaining compatible with standard 400V charging infrastructure.
What is E-GMP?
E-GMP stands for Electric Global Modular Platform, Hyundai’s dedicated architecture for BEVs. It enables high-voltage operation, flexible packaging, and advanced charging capabilities across its lineup, including the IONIQ 5.
- Chemistry: NMC (nickel-manganese-cobalt oxide) cathodes
- Cell format: pouch-type lithium-ion modules arranged into a modular pack
- System voltage: 800V architecture with 400V compatibility for broad charging support
These elements together make the IONIQ 5 capable of rapid charging and efficient energy delivery while maintaining reliability across a wide range of temperatures and usage scenarios.
Battery capacities and configurations
Hyundai offers the IONIQ 5 with two net battery capacities, and with different drive configurations depending on market, producing a range of performance and efficiency outcomes:
- 58 kWh net capacity (Standard Range in many markets)
- 72.6 kWh net capacity (Long Range)
- Drive configurations: Rear-wheel drive (RWD) or all-wheel drive (AWD) options, depending on market and trim
The larger 72.6 kWh pack generally provides longer range and higher total energy delivery between charges, while the 58 kWh option offers lower upfront cost and lighter weight. Battery placement and thermal management are designed to optimize efficiency and longevity in both configurations.
Long-range vs standard options
The two-pack approach allows buyers to balance upfront cost, weight, and range. In markets where available, the 72.6 kWh option is favored for longer trips, while the 58 kWh option suits urban use or tighter budgets.
Charging capabilities and infrastructure
Charging performance is a hallmark of the IONIQ 5, leveraging the 800V platform to support high-power DC fast charging and convenient AC charging as well:
- DC fast charging: up to around 350 kW on compatible chargers (availability depends on market, battery size, and charger compatibility)
- AC charging: onboard charger typically supports up to 11 kW (varies by market and equipment)
- Vehicle-to-load (V2L) capability: enables power delivery from the car to external devices/appliances, up to about 3.6 kW in supported markets
With 800V DC fast charging, drivers can top up significantly faster on compatible high-power stations, while standard home or public AC charging provides convenient daily charging. V2L adds versatility for requiring external power.
V2L power delivery
Vehicle-to-load (V2L) allows the IONIQ 5 to power external devices, such as appliances or tools, using the car’s battery, typically up to 3.6 kW in supported regions.
Manufacturing and platform integration
Hyundai collaborates with LG Energy Solution to supply the battery cells, and the pack is integrated into the IONIQ 5’s Electric Global Modular Platform (E-GMP), the system that underpins all IONIQ 5 powertrain and charging capabilities:
- Cell supplier: LG Energy Solution
- Battery chemistry: NMC (nickel-manganese-cobalt oxide)
- Platform: E-GMP with 800V architecture
The combination of a proven chemistry and the modular pack design allows Hyundai to optimize thermal management, safety, and charging performance across markets.
Supplier and platform notes
LG Energy Solution provides the cells for the IONIQ 5 packs, while the E-GMP platform ensures consistent integration with drivetrain controls, charging hardware, and vehicle systems for a seamless user experience.
Summary
The IONIQ 5 uses high-energy-density lithium-ion battery packs with NMC cathodes, available in 58 kWh and 72.6 kWh options, integrated into Hyundai’s 800V E-GMP platform. These packs support ultra-fast charging, broad AC charging compatibility, and Vehicle-to-Load power delivery, aligning with the model’s emphasis on efficiency, long-range capability, and modern charging infrastructure.
