A battery charger, recharger, or simply charger, [1] [2] is a device that stores energy in an electric battery by running current through it. The charging protocol—how much voltage and current, for how long and what to do when charging is complete—depends on the size and type of the battery being charged.
The DieHard brand is also used on hand tools, power tools, battery chargers, booster cables, power inverters, alkaline batteries, tires, work boots, and the batteries for Craftsman power tools. Battery chargers were initially made by Associated Equipment under the "608" model prefix, and then later Schumacher Electric under the "200" model prefix.
Conventional battery chargers use a one-, two-, or three-stage process to recharge the battery, with a switched-mode power supply including more stages in order to fill the battery more rapidly and completely. Common to almost all chargers, including non-switched models, is the middle stage, normally known as "absorption".
Schumacher soon started selling internationally. The company has always operated out of Northampton [3] but sources some components from China like most other RC companies; however, the majority of manufacturing remains in England. Cecil Schumacher's son Robin Schumacher took over the business in 2001.
Non-contact charging utilizes magnetic resonance to transfer energy in the air between the charger and battery. This achieves a highly efficient energy transformation. [7] As the non-contact charger could keeping charging the vehicle, it allows EVs to have a smaller battery. By itself, it is more economical, safer and more sustainably developed.
The actual voltage, matching the car battery's voltage, will be approximately 12.5 volts when dormant (less in cold conditions), approximately 14.5 volts when the engine and the alternator/generator are operating (more when cold), and may briefly drop as low as 5–6 volts during engine start due to the high temporary battery current usage.

Cars with battery voltages higher than the charger's voltage rating will not be able to charge at all (e.g. chargers with the minimum GB/T voltage of 750V will not be able to charge a 800V battery), though some such as the Hyundai E-GMP and Porsche Taycan can still use lower voltage chargers through the use of a boost converter.
