2、 Technical parameters and core functions

Multi voltage output and current characteristics

Output voltage: Supports 24V/36V/48V

Output current: 22A constant current

Power range:

24V：528W（24V×22A）

36V：540W（36V×15A）

48V：528W（48V×11A）

Applicable battery types:

Lead acid batteries (AGM, GEL, rich solution)

Lithium battery (compatible with BMS protocol, such as lithium iron phosphate LiFePO ₄, ternary lithium NCM)

Charging mode and algorithm

Three stage intelligent charging:

Constant current (CC): Quickly charge the battery to 80% -90% of its capacity with maximum current.

Constant Voltage (CV): The voltage stabilizes at the rated value of the battery, and the current gradually decreases to avoid overcharging.

Float: Maintain low current (such as 0.5A-2A) after being fully charged to compensate for battery self discharge.

Pulse repair: For lead-acid batteries, regularly output high-frequency pulses to break down lead sulfate crystals and extend battery life.

Security protection mechanism

Overcharge protection: When the battery voltage reaches the threshold (such as lead-acid 2.45V/cell), it automatically shuts off.

Short circuit protection: When a short circuit is detected, the circuit is cut off within 0.1 seconds

Over temperature protection: Reduce power when the internal temperature exceeds 75 ℃, and forcibly shut down when it exceeds 105 ℃.

Lightning and surge protection: Built in TVS diode to absorb transient high voltage (such as 4000V lightning strike).

Input under-voltage/over-voltage protection: Automatic power-off when AC input voltage<85v or="">264V.

Input and output interface

Input voltage: AC 100-240V (globally applicable, 50/60Hz), suitable for unstable voltage environments.

Output interface:

Lead acid battery: can use Anderson plug (SB50/SB175 specification) or M8/M10 stud.

Lithium batteries: can be matched with dedicated interfaces (such as H4, XT90, aviation plugs).

Protection level: IP20 (fan-cooled)

Heat dissipation design: Aluminum casing+fan for forced heat dissipation, ensuring long-term high-power operation.

3、 Applicable scenarios and user needs

Industrial Logistics and Warehousing

Electric forklift: 24V/48V models can be quickly charged, reducing downtime (such as a 24V 100Ah battery, a 22A charger takes about 4.5 hours to fully charge).

Transporter: 24V model for high-frequency short distance transportation, supporting 24-hour shift operation.

Stacker: 36V/48V system, meeting the requirements of heavy-duty (such as 2 tons or more) operations.

Factory and Workshop

Electric tractor: 48V high-power charging, suitable for long-distance transportation (such as over 5km).

Automation equipment: AGV (Automated Guided Vehicle) battery pack charging, supporting centralized management of multiple vehicles.

Cleaning equipment: floor scrubbers, sweepers, and other 24V/36V models to improve cleaning efficiency.

Special application scenarios

Backup power supply: To charge UPS or emergency lighting systems, customized interfaces and protocols are required. 

Mining equipment: Explosion proof charger (requiring Ex certification), suitable for underground electric vehicles.

4、 Purchasing Guide and Precautions

Voltage and current matching

Confirm battery voltage: The charger voltage must be completely consistent with the battery (for example, a 48V battery requires a 48V charger).

Current demand:

22A is suitable for 50-200Ah batteries, and the larger the capacity, the longer the charging time.

If the battery capacity is>200Ah, it is recommended to choose a higher current (such as 30A/40A) charger.

Example calculation:

48V 100Ah battery, charging time of 11A charger ≈ 100Ah ÷ 11A =9.1 hours.

Compatibility of battery types

Lead acid batteries: Choose a charger that supports pulse repair to extend their lifespan.

Lithium battery: It is necessary to confirm that the charger supports BMS communication to avoid overcharging or over-discharging.

Mixed use: Some chargers support dual mode switching between lead-acid/lithium batteries (manual setting required).

Use safety and maintenance

Environmental requirements:

Temperature: -20 ℃~40 ℃ (optimal), avoid high temperature direct exposure or low temperature freezing.

Operating standards:

Check the battery level (lead-acid battery) and interface cleanliness before charging.

Do not charge in confined spaces to prevent hydrogen accumulation (lead-acid batteries).

When stored for a long time, disconnect the charger from the battery.

Abnormal battery heating: Immediately cut off the power and check for battery aging or short circuit.

Applications

Wheelchairs, e-Bikes, Sport Gears, Motorbikes, Caravans, Hydraulic Lifts, Farming Tools, Boats, Yachts
