Recharge modes of electric cars.
There are different modes of recharging in the market and they have to do with the level of communication between the electric vehicle and the recharging infrastructure (and therefore the electrical network), and the control that can be had of the charging process, to program it, see the status, stop it, resume it, or even dump electricity into the network.
Mode 1: Domestic Schuko type plug with no communications between charging infrastructure and electric vehicle. In other words, it has no communication with the network. A conventional plug is used for this recharge mode.
Mode 2: domestic wall plug Schuko, with pilot function systems included in the cable. The cable has an intermediate pilot control device that serves to verify the correct connection of the vehicle to the network. It has a communication with the low network.
Mode 3: Has a high level of communication with the network. The control devices and protections are located within the recharging point itself, and the cable includes integrated communication pilot wire. For example, the connectors SAE J1772, Mennekes (IEC 62196) can be used
Mode 4: With a high level of communication with the network. There is a DC converter and only applies to fast recharge. For example, the CHAdeMO or COMBO DC connector.
Types of recharging electric cars.
Los tipos de recarga de los coches eléctricos se clasifican según la velocidad de esta. Es decir se clasifican según el tiempo que tardamos en recargar la batería, algo que depende de la potencia disponible. Actualmente hay cinco tipos de recarga de coches eléctricos.
The recharge types of electric cars are classified according to the speed of this. That is, they are classified according to the time it takes to recharge the battery, something that depends on the available power. Currently there are five types of electric car recharge.
1.- Ultra-fast recharge for electric cars. Its use is not very common, it is in an experimental state in electric vehicles tested with accumulators of supercapacitor type, (for example some electric buses). The batteries can be recharged in five or ten minutes, the recharge power is very high. Lithium-ion batteries do not withstand the high temperature caused by this type of recharging, as it severely deteriorates its useful life.
2.- Fast recharge of electric cars. The power that is demanded is very high, between 44 and 50 kW. Recharging those 22 to 24 kWh batteries can take half an hour. The normal thing is that you do not recharge 100% but around 80% or 90%.
3.- Semi-fast recharge of electric cars. The duration of the recharge ranges from one to four hours. It is done at a power of about 22 kW. This form of recharging is very common in Renault, its low-cost chassis Charger for example that is compatible with Renault Zoe.
- Slow recharge of electric cars. This form of recharge is what we usually call normal or conventional. The batteries are usually recharged between six and eight hours and are performed at 16 A, demanding about 3.6 kW of power.
- Super-slow recharge of electric cars. When the current intensity is limited to 10 A or less because there is no recharging base with adequate protection and electrical installation. The full recharge of the batteries of an average electric car, about 22 to 24 kWh capacity, can take between ten and twelve hours.
