BYD DOLPHIN

This page covers the maintenance requirements for the BYD DOLPHIN pure electric hatchback in the Australian market. As a pure electric vehicle (BEV) featuring a permanent magnet synchronous motor and front-wheel drive, it has no petrol engine, no engine oil, no spark plugs, and no exhaust system to maintain. This independent guide outlines the official service schedule, routine checks, and warranty expectations.

Please note that trim names, specifications and prices reflect a compiled dataset (October 2026) and that BYD Automotive Australia may update variants, so every figure must be confirmed with an authorised BYD dealer or the official BYD Australia website. Official service/warranty page: https://bydautomotive.com.au/service-and-warranty. Because official pricing is not published on the model page, any exact BYD Dolphin driveaway price in Australia must be obtained directly from the dealership network.

Official Service Schedule and Intervals

Maintaining an electric vehicle involves periodic checks of the electrical architecture, thermal management systems, and traditional chassis components. The official BYD Dolphin service intervals of 12 months or 20,000 km apply to all variants, including the Essential and Premium models. According to the manufacturer, scheduled visits are due at:

  • 20,000 km or 12 months
  • 40,000 km or 24 months
  • 60,000 km or 36 months
  • 80,000 km or 48 months
  • 100,000 km or 60 months
  • 120,000 km or 72 months

These milestones apply whichever comes first. Under severe operating conditions, intervals may need to be shortened. For exact details regarding severe usage, refer to the official owner’s manual. The manufacturer does not list a comprehensive BYD Dolphin capped price servicing guide for Australia in the provided documents, meaning official service prices and per-item intervals are not published here. You should consult an authorised BYD dealer for current maintenance pricing and detailed workshop data, which remain a known data gap in the official public literature.

Logbook Items and Fluid Replacements

The exact items recorded in the official service record for the EV series include:

  • Replace brake fluid
  • Replace e-motor controller coolant

The BYD DOLPHIN features ventilated front discs and rear discs, alongside regenerative braking. For questions regarding a BYD Dolphin brake pad life and disc wear inspection, refer to the official owner’s manual or consult an authorised BYD dealer. Any adjustments or fluid replacements must be completed by an authorised BYD dealer or qualified technician.

Fluid types, capacities, and torque figures are subject to manufacturer specifications. Because detailed part numbers and aftermarket part prices are not published, owners should speak directly to the official service centre to ensure correct materials are used for maintenance.

Battery Care and Charging System Maintenance

The BYD DOLPHIN is powered by the BYD Blade Battery, with the Essential variant featuring a BYD Dolphin battery capacity of 44.9 kWh and the Premium variant holding 60.48 kWh. Proper battery care is necessary to preserve the NEDC range (up to 410 km for the Essential and 490 km for the Premium) and WLTP range (340 km and 427 km, respectively).

To maintain battery health, the handbook advises keeping the power battery at a 40% to 60% state of charge if the vehicle is unused for more than 7 days. If unused for more than 3 months, it must be fully charged and then discharged back to 40% to 60% every 3 months. The manufacturer warns that the battery must be recharged promptly if it drops to 0%, as damage from failing to do so is not covered under warranty.

Charging equipment requires basic periodic inspection. The vehicle uses an AC charging port (Type 2) and supports a BYD Dolphin DC fast charging rate via CCS2 at 60 kW for the standard range or 80 kW for the extended range. For an accurate BYD Dolphin home charging cost per 100km in Australia, owners must refer to their specific electricity tariffs. Fully charging the battery at least once a week is recommended by the manufacturer, and completing a full charge from below 10% via AC charging every three to six months aids range estimation. In temperatures below 10 degrees Celsius, it is recommended to charge right after use.

High-Voltage System and Safety Warnings

The electric powertrain operates at high voltages that are extremely dangerous. The high-voltage orange cables must not be touched or opened by owners under any circumstances. Dangerous work, including repairs to the high-voltage system, brakes, steering, airbags, and ADAS calibration, must be done by an authorised BYD dealer or qualified technician.

Attempting unauthorised modifications or third-party conversions will void the manufacturer warranty. This includes software modifications, tuning, or bypassing the battery management system. There is no gas program for this vehicle, and any modifications to the permanent magnet synchronous motor or its controllers are strictly prohibited. Always confirm with BYD Automotive Australia if you are unsure about the safety or compliance of an accessory or repair procedure.

Warranty Coverage and Compliance

The BYD DOLPHIN comes with a New Vehicle Warranty of 6 years or 150,000 km, which covers the vehicle from the date of first registration (or from the date of delivery in Western Australia). The power battery and drive unit (comprising the drive motor and drive motor controller) are covered for 8 years or 160,000 km, whichever occurs first, with a guarantee of at least 70% battery capacity retention.

For the warranty to remain valid, owners must follow correct charging procedures and ensure the vehicle is serviced strictly per the manufacturer’s recommendations. Normal wear and tear, tyres, wheel alignment, brake linings, and wiper blades are not covered under the main warranty. Additionally, damage caused by water ingress from deep-water wading, racing, or loading beyond the gross vehicle mass (1,916 kg for the Essential, 2,068 kg for the Premium) is excluded.

Genuine spare parts imported by BYD Australia, bought by owners, and installed by an authorised BYD Retailer are covered for 12 months from the date of purchase. To claim any repairs under the warranty framework, always consult an authorised BYD dealer.
