The alternator might not be charging the battery
im not gonna swear to this but maybe a short in computer?
Low battery power, or probably a loose battery terminal or ground wire. Follow and check em all...!!
Electrical power is expressed in watts or in jouls per secondAnother AnswerThere is no such thing as 'electrical power'. Power is simply a rate: the rate of doing work. Power can be measured in watts (in the SI system) or in horsepower (in the Imperial system). There is no reason why the power of a heater can't be measured in horsepower or the power of a car can't be measured in watts.
You have a loose electrical connection.
The charging system may be faulty or you may have a parasitic draw. Its also possible that you have a loose connection, or you have an electrical and/or computer problem.
i would say loose power
Sounds like a loose electrical connection, possibly a loose ground connection.
Arcing. The electrical current jumps across the air gap in the loose connection. This creates heat. .
A loose earth/ground wire can prevent any of the electrical components from functioning.A loose earth/ground wire can prevent any of the electrical components from functioning.
Defective, corroded, or loose battery cable.
It depends on whether you mean electrical power or mechanical power. The electrical power comes from the on-board batteries. The mechanical power comes from the motor. The motor is what makes the electrical power turn into mechanical power this is what goes through the drive train to propel the wheels.The Electric car will get its electrical energy from the batteries. The electrical energy is then converted into mechanical energy by the motor. The mechanical energy is then transfered into the wheels providing the power needed to achieve propulsion.
Power is created by the engine to drive the car and to provide electrical power through the alternator.
