Recharge types for electric cars
This 2020, in Enel X we have a new challenge: to start with the implementation of new chargers for electric cars and thus in 2025, reach the goal of 1,200 chargers installed around Chile.
But before finishing installing the charging infrastructure, we want to explain in the best way the different types of recharging and how much time you will need to fully charge the battery, according to the capacity of each technology.
1. JuiceBox (up to 22 kW) - residential charger
Do you want to know how an electric car charger works? The vehicle is plugged in for approximately 8 hours to get a full charge. The conventional single-phase load uses the electric current and voltage of the same level as the house itself, that is, 16 amps and 230 volts.
This solution is optimal, fundamentally, to recharge the electric vehicle at night in a garage of a single-family home or community garage. To make the electric vehicle a reality and taking into account the current electrical system, the optimal recharge from the point of view of energy efficiency is to perform this type of recharge during the night period, which is when less energy demand exists.
With the Enel X JuiceBox equipment, which can give powers in your home of up to 22 kW, and with the connectivity capacity that it includes, loads can be made in less time in stages of lower energy expenditure in your home.
2. JuicePole - Semifast recharge
The vehicle is plugged in for approximately 2 to 4 hours, to obtain a full charge, depending on the available power.
The semi-fast load uses 32 amps of intensity and 230 VAC of electrical voltage. This implies that the electrical power that the point can deliver for this type of loads ranges from 7.4 kW to 22 kW.
This recharge solution is optimal for recharges that are carried out in work centers or in areas where the user can stay more than one hour parked (shopping centers, supermarkets, etc).
3. Juice Pump - Fast recharge
The vehicle is plugged in for approximately 30 minutes to obtain a charge of 80% of the battery, obtaining 100% in approximately one hour.
The fast charge delivers the energy in direct current, obtaining an output power of 50kW. The connectors that use this type of recharge are special, with safety systems adapted to the high amperage that circulates through the connectors.
This solution is the one that, from the client's point of view, resembles their current refueling habits with a combustion vehicle. Therefore, it seems suitable for service stations or restaurants located on the main roads, where the user remains a short period of time.
These charges should be conceived as an extension of autonomy or convenience charges. The requirements at the electrical level are greater than in conventional or semi-fast recharging, which may imply the need to adapt the existing electricity network. For this reason and due to the complexity of the installation, the locations where you can install fast recharge technology are smaller.
4. Ultrafast recharge (from 150 kW)
The latest in recharging are ultrafast points, with an output power of 150kW and capable of charging the battery in just three minutes.
