Charging technology is always expensive, especially when it comes to smart alternators. You normally find these fitted to later vehicles from around 2015 onwards, to meet emissions or other regulations (Typically late EURO 5 and EURO 6, or vehicles with stop/start, ad-blue, or regenerative braking).
Traditional DC-DC or B2B charging kits can sometimes be over 5 times the price of a standard split charge kit, but we've put this kit together to try and make this technology a little more affordable.
How does the unit work?
Very simply, the voltage range from a smart alternator can be very wide compared to a standard one. For example, around 12V and sometimes exceeding 15V, clearly neither of these are suitable for charging a leisure battery.
What the DC-DC unit does it convert these voltages to a more stable and constant one to provide an efficient and reliable charge to your leisure battery.
In addition the battery charging is provided in three stages - Bulk, Absorption, & Float (Depending on battery technology).
When using Lithium, the unit also has a reactivation feature for batteries in a low state of charge.
Will it work in my van?
Not only will this kit work with smart alternators, it'll also work with standard ones too. It'll provide a more stable and reliable charge to your leisure battery (extending life & available capacity) over a traditional voltage sensitive relay kit. It'll also allow you to run lithium battery technology.
Such vans as the below will normally have a smart alternator fitted, but if you're not sure, or your van isn't listed, please just drop us a message and we should be able to confirm its technology.
- Late Volkswagen Transporter T5.1
- Volkswagen Transporter T6
