Tesla Cybertruck 2025-2026 High Voltage Components

High Voltage Components

  1. Front drive unit (if equipped)
  2. Heat pump assembly
  3. High voltage cables
  4. High voltage Battery
  5. Service access panel for high voltage components (ancillary bay)
  6. Rear drive unit(s)
  7. Charge port
  8. Cargo bed outlets (if equipped)

WARNING: The high voltage system must be serviced only by a trained technician. Do not disassemble, remove, or replace high voltage components, cables, or connectors. High voltage cables are typically colored orange for easy identification.

WARNING: Read and follow all instructions provided on the labels attached to Cybertruck. These labels are for your safety.

WARNING: In the unlikely event of a fire, exit the vehicle, move at least 100 ft (30 meters) away, and immediately contact local fire emergency responders.

Charging Equipment

Charging equipment designed specifically for your Cybertruck is available from Tesla. For information about charging equipment in your region, visit Tesla Shop.

  • Wall Connector: Installs in your parking space; fastest for daily use.
  • Mobile Connector: Plugs into most commonly used outlets. Attach the smart adapter before plugging in your vehicle.
  • Adapters: Allow use of most public charging stations. Attach the adapter to the station connector first, then plug into your vehicle.

Superchargers, destination charging, and other fast-charging stations are available for travel.

Low Voltage Battery

Cybertruck uses a 48V lithium-ion low voltage battery to power windows, doors, touchscreen, and other systems when the high voltage Battery is unavailable. It also provides redundant power for critical systems such as power steering.

NOTE: 48V low voltage connectors are blue, and wires operating at 48V are marked with blue tape. Using a 48V battery instead of 12V improves efficiency.

WARNING: Low voltage components are always energized. Do not handle cables or connectors while powered; risk of injury or damage exists.

Charging and Energy Consumption

To preserve the high voltage Battery, leave your vehicle plugged in when not in use. The vehicle periodically uses energy for system tests and low voltage battery charging. There is no advantage to waiting until the Battery is low to charge. Avoid discharging to 0% to prevent damage.

The peak charging rate may decrease after multiple DC Fast Charging sessions. Use Trip Planner to warm the Battery en route to Superchargers for faster charging.

Battery Care

  • Never allow the Battery to fully discharge.
  • Battery discharges ~1% per day; over 14 days, ~14% may be lost.
  • Low-power mode activates at ~0% to protect systems; immediately plug in to avoid jump start or low voltage battery replacement.
  • If the vehicle is unresponsive, jump start the low voltage battery or schedule service.

Tips to Maximize High Voltage Battery Health

  1. Charge in ways that protect the Battery:
    • Use Level 1 or Level 2 (wall outlets or Tesla Wall Charger) for daily use; Supercharging for long trips.
    • Keep daily charge limit at ~80%; reserve 100% for long drives.
    • Charge frequently; avoid leaving Battery at 0% or 100% for long periods.
    • For long-term storage, keep Battery at ~50% and plugged in.
  2. Reduce energy consumption when parked:
    • Sentry Mode
    • USB/outlet devices
    • Powershare
    • Climate controls (Dog Mode, Camp Mode, Cabin Overheat, Keep Climate On)
    • Preconditioning
    • Infotainment usage
  3. Adjust usage when parked:
    • Turn off Sentry Mode in safe locations
    • Precondition when plugged in
    • Park in shade on hot days
    • Wait to use infotainment until plugged in

Temperature Limits

Avoid exposing Cybertruck to ambient temperatures above 140° F (60° C) or below -22° F (-30° C) for more than 24 hours.

Submerged Vehicle

If exposed to flooding or submerged, treat as an accident. See Submerged Vehicle Guidance on page 258. Intentional water entry differs; use Wade Mode. Damage from water is not covered under warranty.

WARNING: High voltage system must be serviced only by trained technicians. Never open or tamper with the Battery. High voltage cables are orange for identification.

CAUTION: If Battery falls to 0%, plug it in to prevent permanent damage. Owner maintenance is not required; do not remove coolant filler cap or add fluid.

Opening the Charge Port

The charge port is above the driver's side rear wheel. With the vehicle in Park and a valid key nearby, press the Tesla cable button to open the port.

Other methods:

  • Touch charge port icon on touchscreen vehicle avatar and select Open
  • Controls > Charging > Open Charge Port
  • Press the port door when unlocked with authenticated phone nearby
  • Voice commands
  • Mobile app

The Cybertruck icon lights up white when the port is open. If no cable is inserted within a few minutes, the door closes automatically.

NOTE: In cold/icy conditions, the charge port latch may freeze. Thaw by using rear defrost, mobile app defrost, or charge port heater under Controls > Service. Schedule preconditioning to prevent freezing.

CAUTION: Do not force the charge port door open.

Plugging In

Use the touchscreen to change charge limit and current. For public stations without NACS connector, use adapter. With Mobile Connector, plug into the power outlet before the vehicle.

Insert the connector fully; charging begins automatically after Cybertruck:

  • Engages latch to hold connector
  • Shifts into Park
  • Heats or cools Battery if needed

Charging is recommended while vehicle is not in use to maintain optimal Battery level.
