In the event of an error in the high voltage electrical system, the same system sends an alert to the vehicle operator through the instrument panel. Even in the event that the 12V battery has been discharged, for example “Because you are listening to music without having started the engine”, it is a fairly easy detail to solve, since it is enough to place a simple 12V source with a capacity of 1 Ampere so that it draws enough power to restart your vehicle Great right!

Depending on the version of the hybrid vehicle, They exist with the option of recharging only through the internal combustion engine’s own energy and kinetic energy when driving or, in addition to this, with the option of a domestic charger to save fuel, the latter only as premium equipment depending on the version. .

The powertrain of a hybrid vehicle is mainly made up of the following parts:

• Combustion engine: It is in charge of recharging the HV battery when the vehicle is stopped, in addition to providing propulsion to the vehicle when there is a high demand for power by the operator.

• GM: The motor generators have two types of behavior, when they work as an engine they are in charge of propelling the vehicle or even starting the internal combustion engine; when they behave as generators, they transform mechanical energy into electrical energy to recharge the HV battery. This mechanical energy can come from the combustion engine or it can come from the kinetic energy when the vehicle is moving.

• HV battery: It provides the electrical energy for the propulsion of the vehicle, it has high levels of direct current voltage and its handling should only be carried out by qualified personnel, and although there is nothing to fear due to the fact that it is of high voltage, it is also true that it They run serious risks if not handled correctly.

• Investor: This electronics unit is the interface that exists between the aforementioned components, since it is in charge of putting the MGs in motor or generator mode at the right time, thus ensuring that while the HV control system is in good condition, never run out of power.

This is certainly just a brief overview of hybrid vehicles that is intended to give you peace of mind that a discharged HV battery is highly unlikely, and also reassurance as to what can be done in the event of a discharged auxiliary battery. 12V.

In summary, The battery of a hybrid vehicle will not have to be recharged manually like that of an EV since it is constantly recharged while the vehicle is running, whether in circulation or static.
