A smart charger can respond to the condition of a battery and modify its charging parameters accordingly, whereas "dumb" chargers apply a steady voltage, possibly through a fixed resistance. It should not be confused with a smart battery that contains a computer chip and communicates digitally with a smart charger about battery condition. A ...
Inductive charging is also used in vehicles, power tools, electric toothbrushes, and medical devices. The portable equipment can be placed near a charging station or inductive pad without needing to be precisely aligned or make electrical contact with a dock or plug. Inductive charging is named so because it transfers energy through inductive ...
Battery packs intended for rapid charging may include a temperature sensor that the charger uses to protect the pack; the sensor will have one or more additional electrical contacts. Different battery chemistries require different charging schemes. For example, some battery types can be safely recharged from a constant voltage source.

A lithium-ion or Li-ion battery is a type of rechargeable battery that uses the reversible intercalation of Li + ions into electronically conducting solids to store energy. In comparison with other commercial rechargeable batteries, Li-ion batteries are characterized by higher specific energy, higher energy density, higher energy efficiency, a longer cycle life, and a longer calendar life.
A method for very rapid charging called in-cell charge control involves an internal pressure switch in the cell, which disconnects the charging current in the event of overpressure. One inherent risk with NiMH chemistry is that overcharging causes hydrogen gas to form, potentially rupturing the cell.
ISO 15118 is one of the International Electrotechnical Commission's (IEC) group of standards for electric road vehicles and electric industrial trucks, and is the responsibility of Joint Working Group 1 (JWG1 V2G) of IEC Technical Committee 69 (TC69) [3] together with subcommittee 31 (SC31) [4] of the International Organization for Standardization's (ISO) Technical Committee 22 (TC22) [5] on ...
SAE J1772, also known as a J plug or Type 1 connector after its international standard, IEC 62196 Type 1, is a North American standard for electrical connectors for electric vehicles maintained by SAE International under the formal title "SAE Surface Vehicle Recommended Practice J1772, SAE Electric Vehicle Conductive Charge Coupler".
