Definitions
- the present invention relates to an installation and charging method for electric battery, and more particularly to a fast charge terminal for vehicles equipped with at least one electric battery and an on-board computer.
- the simplest recharging is done using a direct connection, on a so-called normal socket, delivering a current of 16 A at 220 to 240 V, or about 3.7 kVA.
- the alternating current is converted into direct current by the on-board charger of the car. A full recharge takes place in 6 to 10 hours.
- This type of load which can be performed from a conventional home outlet, lies in the absence of the need for any new infrastructure, at least for individuals with a garage or a parking space.
- This type of load also has the advantage of offering the possibility of recharging the vehicle at night during hours, when energy consumption is lowest.
- Charging by fast direct connection requires a dedicated charging terminal, delivering a direct current of a hundred amps, at a voltage currently between 20 and 500 V, directly applied to the batteries of the electric vehicle.
- the installed power is of the order of 50 kVA.
- This type of charging provides, in principle, a range of 3 to 5 km per minute of charge, provided that the batteries are able to absorb high currents without damage. Co-management of the load by intelligent elements present, on the one hand on the electric vehicle and on the other hand, on the fast charging terminal is necessary.
- the fast charging station has a charger-rectifier powered by a three-phase network.
- the amount of energy consumed by the electric car depends mainly on its performance and the distance it travels. Designed for an average of 40 km per day, the electric car requires between 4 and 25 kWh per 24 hours, which gives an annual consumption of between 1,500 and 9,000 kWh. According to the various sources given by GI FAM (Inter-professional group of manufacturers of household equipment) and INSEE, in France, the average domestic consumption of potential users of the electric car would be 8,000 kWh and this consumption would be 1 000 kWh in the United States.
