Porsche Cayenne produced after 2018 (model 9Ya) and Lamborghini Urus use the same battery for engine starting and consumer management.The battery is produced by LG in South Korea and is a LI-ION battery.
The LI-ION battery requires much more attention than a regular car battery.Inside the plastic casing are the battery elements and a battery management system controlled by a microprocessor.
At a discharge below a certain limit the management system disconnects the battery output voltage.When trying to start or open the car there is no reaction, the battery voltage is 0 Volts.
In this situation, if the discharge has been done in a short time and the battery voltage is not less than 10 Volts, the battery can be recharged by applying a voltage of 14 V on the charger's power supply module or from another machine.After applying the voltage the management system switches the voltage output from the battery and the engine can be started.
In the case of a slow discharge, or a discharge followed by a period of time in which no voltage has been applied in order to recharge the LI-ION battery, the voltage of the cells drops and it is impossible to couple the output voltage.
In this case the battery must be reconditioned by re-software and firmware update then directly recharged on the internal elements.
In order not to encounter such cases it is recommended that a Battery maintainer (LI ION) is connected for longer periods of time when the car is not in use.
Such a charger can be purchased on Emag or other sites.
Automotive Solutions Romania has reconditioning solutions for batteries that can no longer be charged.
