The Tesla history you actually own.

Third-party cloud apps like Tessie or TezLab require your Tesla account OAuth token. That token is stored on multi-tenant cloud servers and grants broad vehicle write permissions: unlocking doors, starting drives, monitoring real-time GPS locations, and logging where you park overnight. In addition, continuous server polling prevents vehicle computers from sleeping, creating phantom drain. Carvico is 100% offline via SwiftData. Your vehicle records are stored exclusively on your iPhone and your personal iCloud private database container — zero API login, zero remote commands, zero vampire drain, and zero remote attack surface.

The rated range displayed on your Tesla dashboard is calculated directly by the vehicle's Battery Management System (BMS) from its internal nominal full pack capacity, divided by the fixed EPA test constant (for example, ~230 Wh/mi on Model 3 RWD). When you record your displayed miles at 100% state of charge (or your current miles alongside SoC percentage), Carvico computes your usable pack capacity retention against your vehicle's factory EPA baseline. Over time, it plots your longitudinal degradation velocity and benchmarks your pack retention against 20,000+ fleet curves to detect accelerated wear versus routine calibration drift.

Multiply the total energy delivered by your home EVSE (or metered kWh) by your electric utility rate in $/kWh. For example, replenishing a 60 kWh pack at a residential off-peak rate of $0.13/kWh costs approximately $7.80 for 250 miles of travel (about 3.1 cents per mile). Carvico tracks energy in kWh, separates residential off-peak sessions from commercial DC fast charging, factors in Level 2 inverter conversion losses, and computes your true operational cost per mile.

BMS range drift is an algorithmic calculation error that occurs when a battery is repeatedly charged in a narrow state-of-charge band (for example, 40% to 75%). The vehicle's management software loses precise calibration of the open-circuit voltage curve, temporarily displaying fewer rated miles. Permanent degradation is irreversible chemical capacity loss from solid-electrolyte interphase (SEI) layer growth, lithium plating, and active material dissolution. Carvico's longitudinal tracking separates temporary BMS drift from genuine degradation velocity.

Tesla's New Vehicle Limited Warranty covers battery capacity retention to a minimum of 70% over 8 years or 100,000 to 120,000 miles (depending on the vehicle trim). If usable capacity drops below 70% within the warranty window, Tesla is required to repair or replace the pack. Carvico models your degradation curve to project your buffer above this federal threshold well in advance of warranty expiration.

Electric vehicles weigh 20% to 30% more than comparable internal combustion engine vehicles due to traction battery pack weight (for example, a Model Y weighs nearly 4,400 lbs). Combined with immediate stator torque off the line and rear-wheel camber, tires experience elevated shear stress and accelerated inner-shoulder wear. Carvico sets an aggressive starter rotation schedule of 6,000 miles (10,000 km) to preserve tire tread life and prevent premature replacement.

Yes. Carvico natively supports all battery-electric and plug-in hybrid platforms including Hyundai Ioniq 5 and Ioniq 6, Ford Mustang Mach-E and F-150 Lightning, Rivian R1T and R1S, Chevrolet Bolt and Equinox EV, Porsche Taycan, and BMW i4. Maintenance schedules are tuned specifically for electric vehicles, eliminating oil change prompts while tracking tire rotations, cabin microfilters, and brake fluid moisture tests.
