What Provides Power to a Car?
1 Answers
Electricity in a car comes from the vehicle's battery and alternator. The types of batteries are as follows: 1. Nickel-Cadmium Battery: Nickel-Cadmium Battery (Ni-Cd) Voltage: 1.2V. Service life: 500 cycles. Discharge temperature: -20°C to 60°C. Charge temperature: 0°C to 45°C. Note: Strong fire resistance. 2. Nickel-Metal Hydride Battery: Nickel-Metal Hydride Battery (Ni-MH) Voltage: 1.2V. Service life: 1000 cycles. Discharge temperature: -10°C to 45°C. Charge temperature: 10°C to 45°C. 3. Lithium-Ion Battery: Lithium-Ion Battery (Li-ion) Voltage: 3.6V. Service life: 500 cycles. Discharge temperature: -20°C to 60°C. Charge temperature: 0°C to 45°C. Note: 30%-40% lighter than Ni-MH batteries, with over 60% higher capacity. However, they are not resistant to overcharging, which can cause overheating and structural damage. 4. Lithium Polymer Battery: Lithium Polymer Battery (Li-polymer) Voltage: 3.7V. Service life: 500 cycles. Discharge temperature: -20°C to 60°C. Charge temperature: 0°C to 45°C. Note: An improved version of lithium batteries, using polymer electrolyte instead of liquid, allowing for various shapes and greater stability compared to lithium-ion batteries.
