In hybrid car technology, there are three variants: conventional hybrids, self-recharging and plug-in. The differences between them are more than obvious, but there are two technical approaches that brands rely on for their development. We explain the characteristics of series and parallel hybrids.
If you are thinking of a new car, and that is hybrid, surely that on more than one occasion you have wondered if all hybrids –self-recharging or plug-in hybrid– they all work the same way. But nothing is further from the truth, so the following lines will help you a little more to understand hybrids, from a more technical point of view.
The truth is that technical approaches are not given great importance, nor are some explained that hybrids have two batteries. We are going to answer these two questions below. The principle of hybrid cars is to be more respectful of the environment, so that self-recharging hybrids have a low capacity battery, so they hardly have the energy for a trip in zero emissions mode.
Hybrids are parallel, serial, and serial parallel
Your battery is designed to go continually recharging, especially from braking and deceleration phases, through the motor retention. This is one of the great advantages over the plug-in, because in this mode it is the recharge connected directly to the electrical network that stores the energy in the battery with the highest capacity, above 10 kWh and offering a maximum autonomy in electric mode from 20 kilometers.
Both models have two batteries -propulsion and auxiliary-, the latter of 12 Volts to power the different electrical systems on board. But, technically there are three systems that characterize hybrids. First -“hybridparallel»- refers to a hybrid scheme in which the combustion engine is used for starting, assisted by the electric motor. The two blocks are connected to the drive wheels, but it is the first that mainly moves the vehicle, and the one that is on board most hybrids.
The second “hybridserially»Is somewhat more sophisticated, as the combustion engine is used as a power generator to power the electric motor. It is the “E-Power” system of the new Nissan Qashqai, while the third combines the properties of the previous two, hence it is known as “hybridserial parallel». The electric motor starts and runs at low speed, while for normal driving the combustion engine works, and both when extra power is required. This is the case of the Toyota Prius Hybrid.
