Learn about the history, uses, and types of DC-to-DC converters, which are electronic circuits or devices that convert direct current from one voltage level to another. Find out how switching converters, transformers, and power optimizers work and compare their efficiency and advantages.
Most electric cars have a battery pack voltage below 400 volts. With a maximum charge current of 500 A, up to 220 kW charging is possible. EVSE manufacturers offer CCS chargers capable of outputs beyond 350 kW. The Terra 360 [32] from ABB supports up to 360 kW charging. CCS chargers capable of 400 kW charging include:
Learn about the different types of battery chargers, how they store energy in batteries, and how they adjust the charging current and voltage depending on the battery type and condition. Find out the advantages and disadvantages of simple, fast, and intelligent chargers, and the factors that affect the charging rate and temperature.
The Megawatt Charging System (MCS) is a charging connector under development for large battery electric vehicles. The connector will be rated for charging at a maximum rate of 3.75 megawatts (3,000 amps at 1,250 volts direct current (DC)).
An AC adapter or AC/DC adapter (also called a wall charger, power adapter, power brick, or wall wart) [1] is a type of external power supply, often enclosed in a case similar to an AC plug. [2] AC adapters deliver electric power to devices that lack internal components to draw voltage and power from mains power themselves.
Direct current (DC) is one-directional flow of electric charge, produced by a battery or a generator. Learn about the history of DC, its conversion from alternating current (AC), and its uses in various fields such as power transmission, electronics, and transportation.
In industrial settings such as telecommunications racks, bulk power may be distributed at a low DC voltage (e.g. from a battery backup system) and individual equipment items will have DC/DC switched-mode converters to supply required voltages. A common use for switched-mode power supplies is an extra-low-voltage source for lighting.
Depth of discharge (DoD) is the fraction of a battery's capacity that is removed or used on a regular basis. It can be defined in terms of the state of charge (SoC) or the absolute capacity (Ah) of the battery, and it affects the cycle life and performance of different battery types.
