Overview

Smart Portable Battery Charger is an intelligent three-stage charging equipment for lead-acid batteries. It adopts high-frequency PWM control and dual-CPU redundant design, supporting fast supplementary charging with multiple safety protections. Equipped with HD touch screen and supporting preset charging templates, it is widely used for on-site battery maintenance in power stations, UPS and communication rooms.

Portable Battery Charger | Features

Fast Supplementary Charging Function: It rapidly charges battery packs within a short time to activate internal battery chemicals. It also eliminates voltage difference sparking when closing charging module switches after charging.
Multiple working modes: three-stage charging mode including constant current, constant voltage and floating charge.
7-inch high-definition touch screen with 1024×800 resolution. The multi-layer composite membrane resistive touch panel delivers strong anti-interference performance against electromagnetic interference and transient pulses from power stations, battery rooms and high-frequency chargers. The backlit panel ensures clear data display under all conditions.
Comprehensive safety protections: overcurrent protection, short-circuit protection, over-temperature protection, reverse polarity protection and more.
Multiple alarm functions. Real-time alerts and automatic shutdown will be triggered for abnormalities including overvoltage, undervoltage, out-of-range current and fan failure to protect the equipment.
Intelligent operation design with quick connection ports for easy wiring. It automatically records data and performs intelligent analysis throughout the whole test without manual intervention.
The charging system adopts high-frequency PWM technology, built-in EMI surge protection circuit and microprocessor control technology.
The main control board uses high-performance ARM CPU from STMicroelectronics. Dual-CPU redundant design: the main CPU processes command operation, while the secondary CPU takes charge of alarm monitoring. Both CPUs lock output under emergencies; either CPU can cut off output to guarantee charging safety and reliability.
Presettable charging parameters. Built-in common charging templates for various battery types. Template data can be retained after power failure, enabling direct testing after power-on without repeated parameter setup.
Professional supporting analysis software. It simultaneously displays voltage & current curves, cell bar charts and data tables. It can automatically generate Excel/Word files, support printing and export complete test reports.

FAQ – Smart Portable Battery Charger

Q1: What is a Smart Portable Battery Charger?

A: It is an intelligent three-stage charger designed for lead-acid batteries. It supports fast supplementary charging with constant current, constant voltage and floating charge modes, equipped with comprehensive safety protections for on-site battery maintenance.

Q2: What charging modes does this unit support?

A: It adopts three-stage charging: constant current, constant voltage and floating charge. It also features fast supplementary charging to activate batteries and avoid voltage difference sparking during switch closing.

Q3: Where can this Smart Portable Battery Charger be used?

A: Widely applied in substations, communication base stations, data centers, UPS rooms, railway signal systems, fire emergency power and new energy storage for lead-acid battery maintenance and emergency charging.

Q4: Which battery types is it suitable for?

A: Mainly for VRLA, AGM and flooded lead-acid batteries. It is not applicable to lithium batteries without customized modification.

Q5: What is the advantage of fast supplementary charging function?

A: It quickly charges battery packs to activate internal chemical composition, and effectively eliminates sparking caused by voltage difference when closing charging module switches.

Q6: Can I save my customized charging parameters?

A: Yes. Built-in multiple charging templates for different batteries. Parameter settings can be saved after power-off, and you can start charging directly after power-on without repeated configuration.

Q7: Does the unit require continuous manual monitoring during charging?

A: No. It works automatically with full-process data recording and intelligent analysis. No constant on-site supervision is needed.

Q8: What can the supporting analysis software do?

A: It displays voltage and current curves, single cell bar charts and data tables. Test reports can be exported as Excel/Word files and printed directly.

Q9: Why adopt dual-CPU redundant design?

A: Main CPU handles operation commands, while the secondary CPU monitors alarms. In emergencies, both CPUs lock output; either CPU can cut off output to ensure charging safety.

Q10: What safety protection features are integrated?

A: Overcurrent, short-circuit, over-temperature and reverse polarity protection. It triggers real-time alarms and automatically stops charging for overvoltage, undervoltage, fan failure and other faults.
