The electrification of the automotive industry has led to the emergence of new words that are already part of the automobile nomenclature.
The electrification It has caused a new wave of words, acronyms and new terms to kick in when we describe a novelty in the automotive industry. From the autonomy of the battery, to the acronyms that identify each car, through the types of chargers and new units, such as the kWh, which identifies the capacity of a battery. These are the most important words you should know:
AMP
Unit that measures the intensity of an electrical current, a constant flow over a period of time that passes through an electrical component, such as a cable. Do not confuse amps with volts or watts.
AUTONOMY
It is the distance that we can travel with the energy accumulated in a vehicle without having to stop to recharge. In addition, it is influenced by factors such as: speed, vehicle load and ambient temperature.
APP
Applications that serve to recharge electric vehicles. There are several on the market and they differ depending on the provider of the recharge. There are app aggregators to facilitate use, but we are still far from having the same generic application to reload.
LITHIUM ION BATTERY
Device that stores the electrical energy used to power the motor of the electric vehicle. It works by means of the reversible electrochemical reaction of ions that takes place between the cathode and the anode, generating an electrical current.
BEV
Battery-powered electric vehicle (Battery Electric Vehicle). In electrification there are also PHEVs (plug-in hybrid electric vehicles) and FCEVs, hydrogen fuel cell cars.
BMS (BATTERY MANAGEMENT SYSTEM)
Electronic system integrated into the batteries, manages the load and balances the current, also prevents overcharging or overheating. It is a constant monitor of the state of the battery.
ALTERNATING AND DIRECT CURRENT
The difference between the two is how electrons move within the conductive material. In direct current they move in only one direction and in alternating current two directions alternate.
CCS, MENNEKES o type 2
It is the European standard charging connector, and the one already used by all electrical and almost all plug-in hybrids or PHEVs. It is also called Type 2 or Mennekes, after the company that defined the connector design.
CHADEMO
Japanese connector for fast charging in direct current. It is still used by many Japanese electrics, such as the Nissan Leaf.
COMBO
European fast charging connector. Allows charging up to 350 kW, depending on the charger
SLOW LOAD
This is achieved with a domestic plug -Schuko type-, with single-phase alternating current at 230 V, 16 A and 3.6 kW as maximum power. The time it takes to fully charge will depend on the capacity of the battery, which can range from 5 to 8 hours or even 12.
FAST CHARGE
Recharging system with direct current from 240 kW onwards, up to 600V and 400A, and that charges the battery to 80% in between 5 and 30 minutes. With alternating current, at 500 V and 220 kW (250A) this is achieved in 10 minutes.
REGENERATIVE BRAKING
System that makes it possible to take advantage of braking to generate energy from the friction of the brakes and the rolling. It is braked by running electric motors as generators, recovering part of the kinetic energy to charge the batteries. It can be controlled by the brake pedal, produced when the accelerator is released or even modulated using a radar that detects the car ahead. It allows to recover up to 30% of the energy present in the batteries.
ION-LITIO
It is the combination of minerals that makes possible the chemical reaction in batteries for the generation of electricity.
KILOWATO (kW)
The kilowatt is the unit of power with which the capacity of electric vehicle motors is measured. 100 kilowatts of power equals 100 kW equals 136 hp. In the recharging process, for example, charging at 7.2 kW on a 72 kWh battery takes 10 hours to fully charge.
KILOWATIO/HORA (kWh)
The kilowatt hour is a measurement that reflects how much energy is expended in the given time of one hour. It is not about the number of kilowatts you are using per hour. It is a unit of measurement that is equal to the amount of energy you would use if you kept a 1,000-watt appliance running for one hour.
ONE PEDAL
System that allows managing acceleration and braking with only one pedal (the accelerator). When we lift our foot, the vehicle begins to brake.
RECHARGE POINT
Equipment necessary to power one or more electric vehicles. It consists of the infrastructure in charge of controlling the electric current, the charging terminals and the corresponding parking space.
