Electric Vehicle Charging Station Block Diagram

Every 0 1 seconds the vehicle tells the charging station how much current to deliver following a very specific cc cv charging curve profile defined in the chademo specification and finally it tells it when to stop.

Electric vehicle charging station block diagram. Electric vehicle supply equipment evse the equipments that constitute an electric vehicle charging station are collectively called as electric vehicle supply equipment evse. The vehicle charger tells the charging station through the can bus the battery capacity and at what level to set the voltage. Working of charging station ref 2 8. The level 1 2 charging system for these vehicles consist of an ac dc converter to generate a dc voltage from the ac line.

Technical detail for those of a technical bent here s how a typical dc charging station is configured. Types of electric vehicle charging stations the charge time is dependent on the vehicle s battery capacity and charge acceptance rate 120 vac 1 phase 12 a or 16 a max continuous current ac level 1 250 vac 1 phase 16 a max. Cord with no pilot or auxiliary connections mode 1 ac 250 vac 1 phase. Whether a level 1 residential or level 2 commercial charging subsystem we have the right ingredients to efficiently transmit power from a single phase.

These vehicles are available in a variety of models with varying ranges and capabilities and are plugged in to a source of electrical power to recharge. You can summarize the three concepts derived from one item. The whole setup takes a 12 kv 750 kva feed from the utility steps it down to 480v three phase on site pushes that into 2000a switchgear which feeds four banks of charging units. Some people also refer it as ecs which stands for electric charging station.

Our integrated circuits and reference designs help you create smarter and safer ac charging stations that provide energy to electric vehicles evs. Ac charging stations are the dominant type of plug in vehicle charging type and we expect ac charging to retain its position long term. 1 electric vehicle technology and charging equipment overview 1 1 electric vehicles electric vehicles evs use electric motors powered by electrical energy stored in a battery for propulsion. It is also an editable graphic with text and icon placeholders.

The term is more popular and it refers nothing but to the charging stations. On the input side it has three phase ac mains which are connected to the ac dc power stage. Or 480 vac 3 phase 16 a max. This block converts the incoming ac voltage into a fixed dc voltage of around 800 v.

The price can range from 395 usd for a simple domestic wall box to more than 35 000 usd for a dc charging station japan has more than 2 800 dc fast charging stations using chademo the.
