HYBRID & EV POWER SYSTEMS

Hybrid & EV Power System Components

Modern hybrid and electric vehicles depend on a tightly integrated network of power electronics to move, charge, and stay safe on the road. Unlike a conventional car, where the alternator and starter motor do most of the electrical work, a hybrid or EV relies on high voltage batteries, inverters, onboard chargers, battery management systems, DC/DC converters, and a range of high voltage safety components working together as one system.

When any one of these parts fails, a battery pack losing capacity, an inverter throwing a fault code, a DC/DC converter no longer charging the 12V battery, the whole vehicle can be affected, from a dashboard warning light to a complete loss of drive power.

At Aerosell, we supply new, used and refurbished OEM hybrid and EV power system parts, from complete batteries down to individual modules, each tested before shipping and backed by a 12-month warranty. Whether you’re a workshop diagnosing a specific fault code or an individual replacing a failed part, browse the categories below to find the exact component your vehicle needs.

New, Used & Refurbished OEM Parts

Every component listed below is available in new, used or refurbished condition depending on the make and model, tested before it ships and covered by a 12-month warranty.

Batteries

12V auxiliary, 48V mild hybrid, and high voltage EV batteries, available as complete units or individual modules. See all Batteries & Modules →

Inverters

Converts the battery’s stored DC power into the AC power that drives the motor. See all Inverters →

Chargers

The onboard charger that converts AC power from a wallbox or public charge point into DC for the battery. See all Chargers →

Battery Management Systems (BMS)

Monitors, balances and protects every cell in the battery pack. See all BMS Modules →

DC/DC Converters

Steps high voltage down to 12V or 48V to keep the auxiliary battery charged. See all DC/DC Converters →

High Voltage Components

Contactors, connectors, junction boxes and cables that connect and protect the high voltage system. See all High Voltage Components →

Professional Testing, Warranty & Exchange Service

Every part we sell, battery, module, inverter, charger, BMS, converter or high voltage component, is tested before it leaves our warehouse and comes with a 12-month warranty. On exchange parts, we hold a refundable deposit until your old unit is back with us.
