Applications

The 2kW DC portable charger is a high-power charging device with different types of voltage output options, designed specifically for electric devices that require fast charging or high-power power supply, and supports 24V, 36V, and 48V battery packs. Its core function is to adopt a five stage charging algorithm of pulse+soft charging (CC)+constant current (CC)+constant voltage (CV)+float charging, which efficiently and safely replenishes energy for batteries of different voltages. At the same time, it integrates multiple protection mechanisms such as overcurrent, overvoltage, short circuit, and overheating to ensure stable and reliable charging process. This type of charger is usually equipped with a portable handle, shock resistant housing, and wide voltage input (such as AC 90-264V), suitable for outdoor, industrial, emergency and other scenarios, and is a key component of high-performance electric systems.

Maintenance and upkeep

Usage environment

Temperature control: Avoid using outside the range of -20 ℃ to 40 ℃ to prevent a decrease in battery or charger performance.

Moisture and dust prevention: The charger should be placed in a dry and clean environment to avoid interface oxidation or short circuit.

Ventilation requirements: When charging, ensure that there are no obstructions around. For air-cooled chargers, a heat dissipation space of at least 15cm should be reserved.

regular inspection

Interface cleaning: Clean the charging interface with anhydrous alcohol every month to prevent poor contact from causing heating or sparks.

Voltage calibration: Every six months, use professional instruments to test the output voltage accuracy (error should be ≤± 1.0%) to ensure charging safety.

Cooling system: Check if the fan is running properly, clean the dust on the cooling fins, and prevent overheating protection from triggering.

Storage and transportation

Long term storage: Store in a cool and dry place. It is recommended to charge the battery every 3 months to prevent excessive self discharge.

Transportation protection: Use shockproof packaging to prevent the internal circuit board of the charger from loosening or solder joints from falling off.

Battery isolation: Store the charger and battery separately during transportation to prevent accidental start-up or short circuit.

Battery matching and safety

Voltage consistency: It is strictly prohibited to mix chargers and batteries with different voltages (such as using a 48V charger to charge a 24V battery), which may cause explosions or fires.

Lithium battery specific: Lithium batteries require a charger that supports BMS (Battery Management System) to avoid overcharging or overdischarging.

Reverse connection protection: Confirm the polarity of the interface before charging, some chargers have reverse connection automatic power-off function.

Fault handling and safety

Abnormal heating: If the surface temperature of the charger is abnormal, immediately turn off the power and contact after-sales to avoid damage to internal components.

Odor or smoke: Immediately cut off the power, use a dry powder fire extinguisher to extinguish potential sources of fire, and avoid electric shock caused by water use.

Professional maintenance: It is prohibited to disassemble the charger by oneself. Internal high-voltage components may pose a risk of electric shock and require professional maintenance.
