A vehicle comprises a battery management system () including an electronical control unit (), a battery system () and an electronic battery controller (). The battery controller () includes an acquisition device () for acquiring values of at least one electrical parameter of the battery system () and a memory () storing a battery profile () representative of properties of the battery system (). The electronical control unit () includes: —a storage space () including a plurality of additional battery profiles (), —a selection interface () for selecting a replacement battery profile among the plurality of additional battery profiles (). and is programmed to replace the battery profile () stored in the memory () with the replacement battery profile selected by the selection interface ().

Method for operating a battery system of a vehicle and a vehicle comprising a battery management system

Provided is a method of operating an electrical system including a first battery, a second battery coupled in series with the first battery, and a battery equalizer coupled to the first battery and the second battery and configured to supply an equalizing current to the first battery. The method includes monitoring a level of the equalizing current, determining, based on monitoring of the level of the equalizing current, that the equalizing current is saturated, and reducing a level of current supplied at a positive terminal of the first battery in response to determining that the equalizing current is saturated. The methods may take an action to reduce the demand for current that is supplied by the first battery.

Equalizer overload management

An electrical system for a vehicle having a chassis ground (G) and an engine having an engine ground (G), the system comprising a first electrical energy storage device (), denoted EESD1, a second electrical energy storage device (), denoted EESD2, a starter device () having a starter motor (), a generator (), a first cable () coupling a positive terminal (+) of EESD1 to the positive terminal (+) of the starter device, a second cable () coupling the positive terminal (+) of the generator to a positive terminal (+) of EESD2, a third cable () coupling a negative terminal (&#x2212;) of EESD1 to the negative terminal (&#x2212;) of the starter device, a control unit () for controlling the charge of EESD1, a fusible link () coupling a negative terminal (&#x2212;) of EESD1 to the chassis ground (G).

Vehicle electrical starter circuit protection

A method is provided for controlling the operation of a rear light set of a tractor of a vehicle, the rear light set including a plurality of rear lights, the vehicle further including a trailer which can be pivotably connected to the tractor about a substantially vertical axis and which includes the same set of rear lights. The method including: detecting whether a trailer is connected to the tractor; detecting a steering angle of the vehicle; if a trailer is detected to be connected to the tractor and if there is at least one activated rear light in the trailer rear light set: in case the steering angle of the vehicle is below a predetermined threshold, deactivating at least the rear light(s) of the tractor rear light set which is (are) of the same type as the activated rear light of the trailer rear light set; in case the steering angle of the vehicle is above the predetermined threshold, in a so-called manoeuvring operation, activating at least the rear light of the tractor rear light set which is of the same type as the activated rear light of the trailer rear light set and which is located outside of the turn.
