Lithium Battery Chargers for Lithium Battery Systems

Qiangfeng designs and manufactures lithium battery chargers for battery-powered vehicles, equipment and other lithium battery systems. Charger selection should be based on the battery specifications, charging requirements and BMS configuration rather than nominal voltage alone. Replacement and OEM projects can also be reviewed using the existing battery and charger information.

Typical Applications

AGV & AMR：For automated mobile equipment requiring controlled lithium battery charging and, where applicable, BMS communication.

Electric Forklifts & Material Handling Equipment：For lithium battery systems used in forklifts and other electric material-handling equipment.

Aerial Work Platforms & Scissor Lifts：For battery-powered lifting equipment where charger output, installation conditions and charging requirements need to be matched.

Industrial Floor Cleaning Equipment：For scrubbers, sweepers and other battery-powered cleaning equipment requiring regular battery charging.

Utility Vehicles & Golf Carts：For lithium battery systems used in golf carts, utility vehicles and other low-speed electric equipment.

How to Select a Lithium Battery Charger

Battery Voltage

Confirm the battery's nominal and required charging voltage.

Battery Chemistry

Provide the battery chemistry and recommended charging requirements.

Battery Capacity

Provide the battery capacity to help determine the charger rating.

BMS Configuration

Confirm whether BMS communication is required.

Charging Schedule

Provide the required charging time or daily operating schedule.

BMS & Communication Compatibility

BMS compatibility depends on the communication interface, protocol and charging parameters. CAN or RS485 availability alone does not confirm compatibility.

Communication Interface

CAN and RS485 are available on applicable models.

Communication Protocol

The charger may need to match the battery system's communication protocol and charging parameters.

Electric Forklift Battery Charger suppliers

Information for Verification

For BMS-controlled charging, provide the BMS manufacturer, model, interface and protocol information for technical review.

Choosing the Charging Current

Charging current should be selected according to the battery’s charging limits and the required charging time. A higher-rated charger is not automatically suitable for every lithium battery system.

Battery Charging Limit

The selected current should remain within the charging current specified by the battery manufacturer.

Required Charging Time

A shorter charging time may require a higher charging current, provided that the battery system supports it.

Charger Current Rating

The charger’s rated current should match the required charging range rather than simply using the highest available output.

Charger Configuration

Configuration	Description
Onboard Charger	Installed directly on the vehicle or equipment
Offboard Charger	Installed separately from the equipment
BMS-Compatible Configuration	Configured for supported BMS communication requirements
OEM Configuration	Developed according to agreed electrical, mechanical and identification requirements

Replacing an Existing Lithium Battery Charger

A replacement charger should be checked against the battery charging parameters, BMS requirements, communication interface and connector configuration.

Qiangfeng can review the existing charger and battery information for replacement projects. Where available, provide the charger nameplate, battery datasheet, connector photos and BMS information.

AC input, DC output connector, cable length and equipment-side connection requirements can also be reviewed.

Installation Environment

The installation environment affects the required enclosure protection, cooling method, mounting arrangement and connection requirements.

Indoor Charging

Confirm the available AC supply, ambient temperature, ventilation and installation space.

Outdoor Charging

Check the required IP rating, operating temperature range, weather exposure and mounting conditions.

Onboard Charging

For chargers installed on mobile equipment, consider mounting space, vibration, cable routing, connector access and cooling conditions.

Offboard Charging

For stationary charging, confirm the installation location, AC supply, ventilation and connection arrangement.

Information Reviewed Before Quotation

Before proposing a charger configuration, Qiangfeng can review the following project information:

Electrical

Required charging voltage and current, AC input and charging conditions.

Battery & BMS

Battery model, chemistry, BMS model, communication interface and protocol.

Mechanical

Enclosure dimensions, mounting method, connector type and cable arrangement.

Operating Conditions

Indoor or outdoor installation, ambient temperature, cooling and IP requirements.

Project Requirements

Quantity, OEM/ODM requirements, labeling, documentation and destination market.

Manufacturing & Technical Verification

Qiangfeng carries out production inspection for lithium battery chargers, including applicable electrical, communication and protection-function checks before shipment.

Output voltage and current testing
CAN/RS485 communication testing on applicable models
Protection-function testing
Load or burn-in testing on applicable models
Final inspection and nameplate verification

Technical Documents for Procurement

Depending on the model and destination market, Qiangfeng can provide applicable procurement and technical documentation, such as:

Product datasheet
User manual
Electrical test information
CE-related documentation
UL certification/documentation for applicable models
Product nameplate information
Communication protocol information for applicable models

FAQ

Q: Can Qiangfeng supply samples before a volume order?

A: Sample orders can be discussed for applicable charger models and project requirements before volume production.

Q: Can approved charger specifications be kept for repeat orders?

A: Yes. Once the charger configuration is confirmed, the approved electrical and functional specifications can be used as the reference for repeat production.

Q: Can the charger carry our own model number or product label?

A: For OEM projects, customer-specific model identification and labeling can be reviewed according to the agreed product configuration.

Q: Can a charger configuration be changed after sample approval?

A: Changes can be reviewed before the production order is released. Revised electrical, mechanical or communication requirements should be confirmed before production.

Q: Can Qiangfeng support small-batch lithium charger projects?

A: Project quantities and production arrangements can be reviewed according to the charger model, customization requirements and production configuration.

Q: Can spare chargers be supplied for an existing equipment fleet?

A: Yes. Replacement or spare-unit requirements can be reviewed using the existing charger, battery and equipment information.
