48V Alternator Land Rover 3.0 d Hybrid

The Land Rover code LR190221 identifies a belt-driven alternator for a 48 V mild-hybrid system, called a BISG (Belt-Integrated Starter Generator). This is not a conventional 12 V alternator. The component integrates the functions of electrical generator and starter motor, is driven by the accessory belt and is connected to the vehicle’s 48 V mild-hybrid network. The unit works with the 48 V lithium-ion battery, the DC/DC converter, the 12 V battery and the energy management control units. Technical characteristics: manufacturer: Valeo; nominal voltage: 48 V; charging current up to 250 A; Poly-V pulley with six ribs; pulley diameter approximately 54 mm; four mounting points; indicative weight: approximately 11.2 kg. DIPA can refurbish these components thanks to its experience and expertise. Functions: starts the internal combustion engine during Start&Stop strategies of the mild-hybrid system; recovers energy during coasting and braking; charges the 48 V lithium-ion battery; replaces the conventional alternator within the mild-hybrid electrical architecture; supports the thermal engine during take-off and restart phases; enables faster and less perceptible engine restarts; cooperates with the DC/DC converter to support the 12 V on-board electrical supply; contributes to fuel- and emissions-reduction strategies used by the Ingenium MHEV engines. Model applications: Jaguar F-Pace; Land Rover Defender/Discovery. Typical faults: mild-hybrid system warnings; Start&Stop not functioning; difficulty restarting the internal combustion engine; reduced energy recovery capability. Final conclusions: the Land Rover LR190221 is a BISG rated 48 V and 250 A, intended for Land Rover and Range Rover mild-hybrid architectures with Ingenium 3.0 diesel MHEV engines. The component performs starting, electrical generation, energy recovery and Start&Stop support functions. It is a complex mechatronic unit that depends on the 48 V battery, the DC/DC converter, cabling and the accessory belt drive. DIPA offers a wide range of automotive spare parts, from OEM to selected aftermarket producers, and also supplies remanufactured units restored to like-new performance. If the replacement part you need is not available, DIPA can recondition your unit on demand and return it fully functional in a short time.
