High-Voltage Battery Health Service
Specialized
800-Volt Architecture
The Taycan uses an industry-leading 800-volt electrical architecture — double the voltage of most EVs. This enables faster DC charging (up to 270 kW), more efficient power delivery to the motors, and lighter wiring. The battery pack is available in two sizes: the Performance Battery (79.2 kWh usable) and the Performance Battery Plus (93.4 kWh usable). Battery health service involves monitoring cell voltage balance, measuring total capacity against specification, inspecting the liquid thermal management system, and verifying the Battery Management System (BMS) is functioning correctly.
- 800V architecture: double the voltage of most EVs — requires specialized high-voltage training and equipment
- Performance Battery: 79.2 kWh usable capacity / Performance Battery Plus: 93.4 kWh usable capacity
- Cell voltage balance: PIWIS reads individual module voltages to identify cells that are drifting from the pack average
- Capacity measurement: total usable energy compared to specification quantifies any degradation over time
Safety and Service Requirements
Working on the Taycan's high-voltage system requires Porsche EV certification, specialized insulated tools, high-voltage personal protective equipment, and strict safety procedures. The high-voltage system must be fully de-energized before any service that involves HV components, and insulation resistance testing is performed before and after service to verify electrical isolation. Our technicians hold Porsche EV and high-voltage certifications required for Taycan service.
- Full HV de-energization procedure before any battery or motor service — PIWIS controls the disconnect sequence
- Insulation resistance testing before and after service verifies no HV current paths to the chassis
- Specialized insulated tools rated for 1000V+ required for all HV component access
- Module-level service possible without full pack replacement — individual modules replaced if cell-level faults are isolated
Multi-Circuit Cooling Overhaul
System
Four Separate Cooling Circuits
The Taycan uses four independent cooling circuits: battery thermal management, front motor cooling, rear motor cooling, and power electronics (inverter and DC-DC converter) cooling. Each circuit has its own pump, heat exchanger, and coolant specification. The battery circuit uses a non-conductive coolant to prevent electrical hazards. The motor and electronics circuits use conventional automotive coolant. A complete cooling overhaul addresses all four circuits simultaneously, flushing old coolant, inspecting pumps and heat exchangers, and verifying temperature regulation across the system.
- Battery circuit: non-conductive coolant — standard coolant cannot be substituted
- Front and rear motor circuits: conventional coolant with dedicated pumps and radiators for each motor
- Power electronics circuit: inverter and DC-DC converter cooling with its own heat exchanger
- Each circuit flushed independently with the correct coolant specification — cross-contamination must be avoided
Two-Speed Transmission Service
Specialized
Unique Among EVs
The Taycan is unique among production EVs in using a two-speed transmission on the rear axle. First gear provides maximum torque multiplication for launch acceleration, while second gear provides efficient cruising at highway speeds and enables the Taycan's high top speed (over 160 mph on Turbo S models). The transmission uses a planetary gear set with a dog clutch for gear selection. Fluid service is required at factory intervals to maintain proper lubrication and cooling of the gear set and clutch mechanism.
- Planetary gear set with dog clutch: first gear for launch, second gear for efficiency and top speed
- Transmission fluid service at factory intervals — specific fluid specification for the two-speed unit
- Gear selection mechanism inspected during service: dog clutch engagement and actuator function verified through PIWIS
- Front axle uses a single-speed reduction gear — simpler but still requires periodic fluid service
Air Suspension Service
System
Taycan Adaptive Air Suspension
The Taycan's adaptive air suspension combines air springs with electronically controlled PASM dampers. The system adjusts ride height and damping rate based on driving mode, speed, and road conditions. The air springs provide variable ride height — raised for rough roads and lowered for aerodynamic efficiency at highway speeds. Service involves the same WABCO-type components as other Porsche air suspension systems: air springs, compressor, valve block, and height sensors.
- Air spring bladder inspection: rubber bellows checked for cracking, abrasion, and air leaks
- Compressor and dryer cartridge: compressor duty cycle monitored through PIWIS — excessive running indicates air leaks
- PASM damper integration: active damping adjusts independently from air spring height — both systems calibrated together
- PIWIS ride height calibration required after any air spring or sensor replacement
Charging System Diagnostics
System
800V Charging Architecture
The Taycan supports both AC charging (up to 22 kW with the optional dual onboard charger) and 800V DC fast charging at up to 270 kW. The charging system includes the onboard AC charger, the CCS (Combined Charging System) DC inlet, the high-voltage battery junction box, and the charging control software. Common issues include onboard charger faults (reducing AC charge rate), CCS connector pin corrosion, 12V auxiliary battery drain preventing charge initiation, and software-related charging interruptions.
- Onboard AC charger: tested for output capacity — reduced charge rate indicates charger module fault
- CCS DC inlet: connector pins inspected for corrosion, damage, or thermal discoloration from high-power charging
- 12V auxiliary battery: the 12V system must be healthy to initiate HV charging — replacement resolves many charge faults
- Software updates: Porsche regularly releases charging optimization updates via PIWIS — applied during every service

Taycan Service FAQs
- What maintenance does a Porsche Taycan need?
- The Taycan requires significantly less routine maintenance than combustion Porsches since there is no engine oil, spark plugs, or exhaust system to service. The primary maintenance items include brake fluid changes every two years, cabin air filter replacement annually, tire rotations every 10,000 miles, and a comprehensive multi-point inspection. The regenerative braking system means brake pad life is substantially longer than on conventional cars — often lasting 60,000 miles or more.
- How long does the Porsche Taycan battery last?
- Porsche warranties the Taycan's battery for 8 years or 100,000 miles with a guaranteed minimum of 70 percent capacity retention. Real-world longevity depends on charging habits, climate, and usage patterns. Avoiding frequent DC fast charging, keeping the state of charge between 20 and 80 percent for daily use, and storing the car in moderate temperatures all help preserve battery health. Annual battery health assessments can detect cell imbalances early.
- Does the Taycan two-speed transmission need maintenance?
- The Taycan's rear-axle two-speed transmission is a unique feature among EVs and does require periodic fluid changes. Porsche recommends transmission fluid replacement every 40,000 miles. The single-speed front motor unit also has its own fluid that should be changed at the same interval. Both units are sealed and require PIWIS diagnostics to confirm proper fluid levels and shift calibration after service.
- How much does Taycan brake service cost?
- Brake service costs depend on whether the Taycan is equipped with standard iron rotors or optional PCCB ceramic brakes. Standard brake pad and rotor replacement costs approximately $1,500 to $2,500 per axle. PCCB rotor replacement is significantly more expensive at $4,000 to $8,000 per axle. The Taycan's regenerative braking system substantially extends brake life, so many owners go 50,000 to 80,000 miles before needing pad replacement.
- Can the Taycan air suspension be serviced independently?
- Yes, individual air suspension components including air springs, the compressor, and the electronic valve block can be replaced independently. The Taycan's air suspension is monitored by the vehicle's onboard diagnostics system, which detects leaks, compressor wear, and ride height sensor faults. After any air suspension work, the system must be recalibrated using PIWIS to ensure proper ride height and damping across all driving modes.
