The Chevrolet Volt is a plug-in hybrid and extended-range electric vehicle car that was manufactured by General Motors, and also marketed in rebadged variants as the Holden Volt in Australia and New Zealand and the Buick Velite 5 in China, and with a different fascia as the Vauxhall Ampera in the United Kingdom and as the Opel Ampera in the remainder of Europe.
An N battery (or N cell) is a standard size of dry-cell battery. An N battery is cylindrical with electrical contacts on each end; the positive end has a bump on the top. The battery has a length of 30.2 mm (1.19 in) and a diameter of 12.0 mm (0.47 in), and is approximately three-fifths the length of a AA battery.
The polarity for 12 V DC sockets is center pin positive (+), outer collar negative (−). Reversed polarity will damage some electronic devices. Although the nominal voltage of a 12 V lead acid battery is 12 V DC, when the engine is running the car's battery charging system will bring the system voltage to 13.8 V DC or higher. [11]
ISBN 978-0-444-52745-5. </ref> Self-discharge decreases the shelf life of batteries and causes them to have less than a full charge when actually put to use. [1] How fast self-discharge in a battery occurs is dependent on the type of battery, state of charge, charging current, ambient temperature and other factors. [2]
Battery electric cars are becoming more and more attractive with the higher oil prices and the advancement of new battery technology (lithium-ion) that have higher power and energy density (i.e., greater possible acceleration and more range with fewer batteries). [12] Compared to older battery types such as lead-acid batteries.
Rates up to three times normal charge rate (defined as C, the current equal to the nominal capacity of the battery divided by 1 hour) can be employed for periods of 30 minutes. [18] Fully charging a NiFe cell consists of seven hours at the normal cell rate. In service the amount of charge given is governed by the extent of the previous discharge.
The HSD system has two principal battery packs, the High Voltage (HV) battery, also known as the traction battery, and a 12 volt lead-acid battery known as the Low Voltage (LV) battery, which functions as an auxiliary battery. The LV battery supplies power to the electronics and accessories when the hybrid system is turned off and the high ...
The following table compares official EPA ratings for fuel economy (in miles per gallon gasoline equivalent, mpg-e or MPGe, for plug-in electric vehicles) for series production all-electric passenger vehicles rated by the EPA for model years 2015, [1] 2016, [2] 2017, [3] and 2023 [4] versus the model year 2016 vehicles that were rated the most efficient by the EPA with plug-in hybrid ...
