  At what speed does hybrid switch to gas?

  The point at which a hybrid car switches from electric mode to using its gasoline engine can vary depending on the specific hybrid model and its design. Different hybrid systems operate in different ways, with factors such as driving conditions, battery state of charge and power demand affecting the switch between electric and gasoline power.

  
  

  Generally speaking, most hybrid vehicles are designed to operate in pure electric mode at low speeds (usually up to a certain threshold). Once that speed is exceeded or more power is required, the gasoline engine kicks in to provide additional propulsion or support.
  For example, many hybrid vehicles can operate in electric-only mode at low speeds, such as during city driving or at speeds below 20-30 mph. When you accelerate hard or reach higher speeds, the gasoline engine may kick in to provide the necessary power.
  
  It's worth noting that advances in hybrid technology have led to changes in the way different hybrid models operate. Some modern hybrids are designed to run in electric mode at higher speeds or for longer periods before starting the gasoline engine. Additionally, plug-in hybrids allow you to drive a certain distance in electric-only mode before relying on the gasoline engine.

  What engine you won't find in electric vehicles?

  Electric vehicles (EVs) do not have internal combustion engines, which are common in traditional gasoline or diesel-powered vehicles. The following types of engines are not found in electric vehicles:
  ① Internal Combustion Engine (ICE): This is the most common type of engine found in traditional vehicles. It burns fuel (usually gasoline or diesel) to generate power and drive the vehicle. Electric vehicles do not have an internal combustion engine.
  ② Rotary Engine: Some vehicles, particularly certain models from Mazda, use rotary engines. These engines operate on a different principle than conventional piston engines but still rely on combustion. Electric vehicles do not use rotary engines.
  ③ Wankel Engine: The Wankel engine is a type of rotary engine developed by Felix Wankel. It's different from traditional piston engines but still relies on combustion. Electric vehicles do not use Wankel engines.
  ④ Wankel Engine: The Wankel engine is a type of rotary engine developed by Felix Wankel. It's different from traditional piston engines but still relies on combustion. Electric vehicles do not use Wankel engines.
  ⑤ Turbine Engine: Turbine engines, commonly found in aircraft, generate power by the continuous flow of gases through a turbine. They are not used in electric vehicles.
  ⑥ Two-Stroke Engine: This type of engine completes a power cycle with two strokes of the piston during one rotation of the crankshaft. Two-stroke engines are not used in electric vehicles.
  
  In electric vehicles, the primary source of power is an electric motor that is driven by electricity stored in a battery. This eliminates the need for traditional combustion engines and associated components like a fuel system, exhaust system, and complex transmission systems found in internal combustion engine vehicles.

  What happens if electric car runs out of power?

  If an electric car runs out of power, it becomes immobile until it is recharged. When the battery of an electric vehicle (EV) is depleted, the car will come to a stop, and the driver won't be able to continue driving until the battery is recharged.

  Do electric cars have refrigerant?

  Yes, electric vehicles (EVs) can use refrigerants, especially in air conditioning (AC) systems. Like conventional cars, electric cars are equipped with HVAC (heating, ventilation and air conditioning) systems to control the interior climate for comfort.  These systems use refrigerants to absorb and release heat, allowing for efficient air conditioning.
  Refrigerant in electric vehicles is used in the air conditioning system to transfer heat from the interior of the vehicle to the exterior. The process involves the compression and expansion of the refrigerant, allowing it to absorb and release heat. Refrigerant circulates through the air conditioning system and its properties facilitate cooling and dehumidifying the air before it is blown into the cabin.
  It's worth noting that the type of refrigerant used in a car's air conditioning system can vary, and there have been efforts in recent years to switch to more environmentally friendly options due to concerns about the environmental impact of certain refrigerants.

  Do electric cars have timing belts?

  Electric vehicles (EVs) typically do not have a traditional timing belt because they lack an internal combustion engine with a camshaft and timing mechanism. Traditional timing belts are commonly found in internal combustion engine vehicles and are used to synchronize the rotation of the engine camshaft and crankshaft and control the opening and closing of the engine valves.
  
  In electric vehicles, the power system consists of an electric motor, power electronics and a battery pack. Electric motors do not have the complex valve and camshaft mechanisms required in traditional internal combustion engines that require timing belts.
  
  That said, electric vehicles may have other parts that require maintenance, such as the electric motor itself, the battery pack, and associated cooling systems. Because components and maintenance requirements may vary, it is important to refer to the manufacturer's specific maintenance recommendations for each electric vehicle model.
