The ZIVAN NG3 48V 45A is a 48V 45A lead battery charger designed for autonomous charging of traction batteries in stand-alone version, with CU1 or CU2 curves depending on the battery and selected charging strategy. This version is dedicated to flooded, gel and AGM lead-acid batteries for onboard or fixed applications requiring a single-phase 230 VAC charger consistent with a professional 48 V electrical architecture.
This NG3 version is positioned as a professional 48V lead battery charger focused on system integration rather than consumer use. With charging current up to 45 A, maximum power of 3 kW, forced-air cooling, an IP20 enclosure and auxiliary contacts, it addresses integrators looking for reliable charging on lead-acid batteries without depending on a lithium control logic managed by a BMS.
The role of this ZIVAN NG3 48V 45A charger is to convert a single-phase 230 VAC supply into stabilized charging energy for a 48 V lead-acid battery pack, with a current level suited to light traction, service batteries or onboard charging on electric machines. The 50 / 60 Hz operating range, maximum absorbed power around 3 kW and constant-current / constant-voltage charging principle make it a serious basis for architectures requiring more controlled charging than a simple workshop charger. In a new project or replacement context, the value of the NG3 lies both in its charging capacity and in its ability to be integrated cleanly into a full battery, protection, wiring and maintenance architecture.

The version covered here must be understood as a stand-alone lead-acid version. This means the product page is limited to flooded, gel and AGM lead-acid battery applications, and the operating logic relies on stand-alone mode with CU1 or CU2 curves. In practice, CU1 corresponds to an IUIa charge profile with equalization and maintenance, while CU2 follows an IU1U2ob logic. This is a key selection point: for a 48V 45A lead battery charger, the correct nominal voltage and current are not enough if the selected curve is not consistent with the battery technology, available charging time and actual operating profile of the machine.
The NG3 format remains relevant when a 48V 45A charger must stay onboard a vehicle or be installed in a protected technical compartment. Its IP20 enclosure requires installation in a sheltered, ventilated and mechanically stable area, but this constraint comes with a compact layout for its power class, with dimensions of 430 x 220 x 110 mm and a base weight of 6.88 kg. For integrators, this makes installation easier in light electric utility vehicles, scrubber machines, mobile platforms, material handling equipment or special-purpose machines powered by a 48 V system, provided sufficient clearance is maintained around the charger to preserve forced-air cooling.

| BATTERY CHARGERS |
The value of a stand-alone 48V lead battery charger like this NG3 becomes especially clear in maintenance, retrofit or fleet standardization contexts. When equipment still operates with lead-acid batteries, it is not always relevant to switch immediately to a lithium logic or to a more complex communicating architecture. A dedicated lead-acid version allows charging to remain readable, robust and easy to bring back into service, while still providing useful signals through auxiliary contacts. This relative simplicity is a real advantage for field equipment where availability, ease of diagnosis and repeatability of maintenance matter more than sophisticated data exchange.
This onboard 48V charger is well suited to applications still using traction or service lead-acid batteries and requiring a higher charging current than a small compact charger. It can be relevant on light industrial electric vehicles, cleaning machines, rolling platforms, special-purpose equipment, electric carts or 48 V architectures requiring onboard or wall-mounted charging in a controlled technical environment.
From an integration standpoint, sizing must account for several parameters beyond the nominal product sheet. A 48V 45A lead battery charger requires verification of actual battery pack capacity, usual depth of discharge, available charging window, cable cross-section, connection quality and compartment ventilation. Lead-acid charging is sensitive to curve selection, temperature and voltage drop across wiring. It is therefore preferable to validate charger behavior on the final wiring and with the actual battery in use, rather than drawing conclusions from a simplified workshop test that does not reflect real operating conditions.
For replacement, refurbishment or fleet harmonization, the NG3 48V 45A can also be a relevant option when it is necessary to keep lead-acid technology and secure regular charging without redesigning the whole machine architecture. In that context, the gain does not come only from the available charging current, but from the ability to stabilize the charging function around a single, identifiable, parameterizable charger compatible with several lead-acid battery families, provided the correct curve is selected.
Which batteries does this charger accept?
This version is dedicated to 48 V lead-acid batteries, especially flooded, gel and AGM types.
What is the difference between CU1 and CU2?
CU1 and CU2 are two different charging logics. The right choice depends on the expected end-of-charge behavior and the battery technology actually installed.
Is this charger suitable for a lithium battery?
No. This product page is intentionally limited to the stand-alone lead-acid version. Lithium or CAN-controlled variants belong to a different product scope.
Can it be mounted onboard a vehicle or machine?
Yes, provided a protected and ventilated compartment is designed for an IP20 charger with forced-air cooling.
The ZIVAN NG3 48V 45A is a relevant basis for projects requiring a stand-alone 48V lead battery charger, with a current level suited to traction batteries and a charging logic adjustable through CU1 or CU2 curves. Its real value is measured by the overall integration quality of the battery, charger, wiring and ventilation. Final validation must therefore always be carried out at full system level before commissioning.
