Seasonal Technical Problems

Development of technical solutions for weather-related problems (winterisation, heat-related failures)
Frozen spring-loaded brakes: implementation of heating systems to prevent freezing
Frozen toilets: Installation of heated piping and insulation systems to prevent frost damage
Frozen air conditioning systems: Use special coolants and robust compressors that can withstand extremely low temperatures
Frozen steps: Development of heated steps and anti-ice systems to ensure functionality
Integration of high-performance air conditioning systems that work efficiently even at high temperatures, optimisation of ventilation systems to prevent overheating
Use of heat-resistant materials and components, and implementation of cooling systems to prevent failure of electrical subsystems

Problems with the Energy Supply in Vehicles
Analysis of power supply interruptions that affect the operation of lighting, air conditioning and other electrical systems
