Primary High-Voltage Components

• Rechargeable Energy Storage System (RESS): The main traction battery pack is a 60 kWh lithium-ion assembly located under the vehicle floor (Recurrent Auto, 2025). It contains 288 individual cells arranged in 10 modules
• Single-Speed Electric Drive Unit: This housing contains the three-phase AC permanent magnet motor and the reduction gearset (transmission). It converts electrical energy from the battery into mechanical torque to drive the front wheels (eBay Motors, 2026).
• Power Inverter Module (PIM): Located in the motor compartment, the PIM (or Traction Power Inverter) converts the DC electricity from the battery into three-phase AC electricity to power the drive motor. It also handles regenerative braking by converting AC back to DC to charge the battery (GM OEM Parts Online, 2026).
• On-Board Charger (OBC): This module converts AC power from a Level 1 (120V) or Level 2 (240V) charging station into DC power to charge the high-voltage battery (ChargePoint, 2017).
• Accessory Power Module (APM): Often referred to as the DC-DC converter, this component reduces the high-voltage (350V+) DC from the traction battery to approximately 14V DC to power the vehicle’s 12V accessories and charge the standard 12V lead-acid battery (Seattle Automotive, n.d.).
• High-Voltage Air Conditioning Compressor: Unlike traditional vehicles, the Bolt uses an electric motor driven by the HV battery to run the A/C compressor, allowing the climate control to function without an idling engine.
• High-Voltage Coolant Heater: This resistive heater uses power from the HV battery to warm the cabin and maintain the battery pack’s thermal management system in cold weather.
