OTA Software Patch: Toyota has begun pushing firmware version 2.4 to BZ4X electric crossovers, introducing manual and navigation-linked battery thermal preconditioning that cuts cold-climate DC charge times by half.
Active PTC Heater Cycling
The revised software activates the high-voltage PTC coolant heater 30 minutes prior to arriving at a programmed DC fast charger, raising core cell temperatures to 25°C to accept peak 150kW charge currents.
Display Telemetry Enhancements
The instrument cluster now displays real-time battery state of charge percentages and estimated charge completion times under active thermal conditioning.
