Introduction

The Ultra Power UP200 DUO is a twin-channel charger with two independent circuits, capable of charging two different types of batteries simultaneously. It supports power distribution in AC mode (total power 100W, CH1+CH2=100W) and in DC mode (2x100W). Features include terminal voltage setting, Battery Meter, PC control for firmware upgrade, Automatic Charging Current Limit, Capacity Limit, Temperature Threshold, and Processing Time Limit.

UP200 Duo Specification

Intelligent Power Distribution in AC Mode:

1. Output power is based on CH1+CH2=100Watt (e.g., 100W+0W, 80W+20W, 50W+50W).
2. If only one channel is used, it can reach up to 100W (Channel 1) or 50W (Channel 2).
3. If both channels are used, CH1 power = 100W - CH2 power.
4. Starting Channel 2 while Channel 1 is at 100W will reduce Channel 1's output.

Special Features

• Optimized Operating Software: Features AUTO function for automatic current setting during charging/discharging. Prevents overcharging and alarms on malfunction. Controlled via two-way linkage and communication for safety and ease of use. Settings are user-configurable.
• Balancing Individual Cells For Battery Discharging: Monitors and balances each cell during discharge. Displays error messages and stops the process if any cell voltage is abnormal.
• Adaptable to Various Type of Lithium Battery: Supports LiPo, Lilon, LiFe, and LiHV batteries.
• Fast and Storage Mode of Lithium Battery: 'Fast' charge reduces charging duration, while 'store' mode controls final voltage for long-term storage and battery protection.
• Cyclic Charging/Discharging: Allows 1 to 5 cycles of charge/discharge or discharge/charge for battery refreshing and balancing.
• Re-Peak Mode of NiMH/NiCD Battery: Charges the battery once, twice, or three times consecutively for full charge confirmation and fast charge reception assessment. Includes a five-minute cool-off delay after each re-peak charge.
• Data Store/Load: Stores up to 10 different charge/discharge profiles for quick recall without re-setting parameters.
• Terminal Voltage Control (TVC): Allows adjustment of the end voltage.
• LiPo Battery Meter: Enables checking of total voltage, highest voltage, lowest voltage, and individual cell voltages.
• Maximum Safety (Delta-peak sensitivity): Automatic charge termination for NiMH/NiCd batteries based on Delta-peak voltage detection.
• Automatic Charging Current Limit: Sets an upper limit for charging current for NiMH/NiCd batteries, especially useful for low impedance batteries in 'AUTO' mode.
• Capacity Limit: Automatically stops the process when the charging capacity exceeds the set limit.
• Temperature Threshold: Terminates the process if the battery temperature reaches the set limit. Requires an optional temperature probe (not included).
• Processing Time Limit: Limits the maximum process time to prevent defects.

Charging

During charging, electrical energy is supplied to the battery, calculated by charge current multiplied by charge time. Use only batteries rated for quickcharge at higher rates than standard. Connect the battery with correct polarity (red positive, black negative). Ensure the charge lead has adequate conductor cross-section and high-quality connectors. Always follow the battery manufacturer's recommended charging methods, especially for lithium batteries. Lithium battery packs can be wired in parallel or series; ensure correct configuration and voltage. Imbalanced voltage can cause fire or explosion. Series charging is recommended for lithium batteries.

Discharging

Discharging cleans residual capacity or reduces battery voltage to a defined level. Set the final discharge voltage correctly to avoid deep discharging. Lithium batteries should not be discharged below their minimum voltage to prevent capacity loss or failure. Generally, lithium batteries do not require discharging. Pay attention to minimum lithium battery voltages for protection.

Memory Effect: NiMH and NiCD batteries can suffer from memory effect if partly used and recharged before a full charge cycle. NiCD has a stronger memory effect than NiMH.

Lithium batteries are best discharged partially. Avoid frequent full discharging. Charge more often or use a larger capacity battery. Full capacity is reached after 10 or more charge cycles. Cyclic charge/discharge optimizes battery pack capacity.

Lithium Battery Connection Diagram

The UP200 Duo can be powered via AC (100-240V) or DC (11-18V) input. Ensure the charger is powered ON before connecting a battery. Incorrect connections can cause charger failure. If a "Reverse Polarity" warning appears, disconnect the battery immediately and never remove power from the charger first.

Crucial Steps Before Connecting:

• Double-check that charging parameters are set correctly. Incorrect settings can damage the battery or cause it to explode.
• Verify correct polarity of wiring from charger to battery.
• Connect charge leads to the charger first, then to the battery to avoid short circuits.
• When disconnecting, unplug the battery from the charge leads first, then remove leads from the charger.

BALANCE SOCKET: Connect the balance wire to the charger, aligning the black wire with the negative marking. Maintain correct polarity.

CONNECTING THE BATTERY: Follow these procedures for connecting a lithium battery with a balance plug:

1. Connect charge leads to the charger, ensuring correct polarity.
2. Turn on the charger and verify settings match the intended battery.
3. Connect the main leads of the battery to the charger's main leads.
4. Connect the balance lead to the correct balance port on the multi-balance board. Consult your dealer if unsure about the socket.
5. Start the charge cycle and monitor the screen for correct readings.
6. When charging is finished, disconnect the balance lead, then the battery main leads.

Program Flow Chart

The document includes detailed flow charts illustrating the programming sequences for various battery types (LiPo, Lilon, LiFe, LiHV, Pb, NiCd, NiMH), including charging, discharging, fast charging, storage, cyclic modes, and battery meter functions.

Lithium Battery (LiPo/LiFe/Lilon/LiHV) Program

These programs are suitable for charging and discharging lithium batteries with nominal voltages of 3.7V, 3.3V, and 3.8V per cell. They utilize Constant Voltage (CV) and Constant Current (CC) methods. Charge current varies with battery capacity and performance. The final charge voltage must precisely match the battery's charge voltage (4.2V for LiPo, 3.6V for LiFe, 4.1V for Lilon, 4.35V for LiHV). Ensure correct charge current and nominal voltage settings for the cell count.

Charging Lithium Battery at Balance Mode

This function balances lithium-polymer battery cells during charging. The battery must be connected with its power lead and balance wire. The charger's internal processor monitors individual cell voltages and controls charging current to equalize them. Charging lithium batteries with a balance wire in balance mode is recommended.

Charging of Lithium Battery

This mode is for charging LiPo/LiFe/Lilon/LiHV batteries in normal mode. Balance mode charging is recommended.

'Fast' Charging of Lithium Battery

In fast charge mode, the charging current drops towards the end of the process. The CV process is reduced, with charging current reaching 1/5 during the CV period. Charging capacity may be slightly less than normal charging, but the time is shorter.

'Storage' Control of Lithium Battery

This function is for charging/discharging batteries not used immediately. It's designed to bring batteries to a specific original state. Programs are classified by types: 3.7V Lilon, 3.8V LiPo, 3.3V LiFe, and 3.9V LiHV. The program will discharge if the original state exceeds the storage voltage level.

Discharging Lithium Battery

Discharge current should not exceed 1C. The right-side value should not be under the manufacturer's recommended voltage to avoid over-discharging. Press START/ENTER for more than 3 seconds to begin discharging. The screen displays the number of cells set up and detected by the processor. If they match, charging can commence. Otherwise, use the BATT TYPE/STOP button to go back and recheck cell count. The screen shows real-time discharging status; press BATT TYPE/STOP to stop.

Pb Battery Program

This program is suitable for charging Pb lead-acid batteries with nominal voltages from 2 to 20V. Pb batteries differ from NiMH/NiCD and deliver lower current relative to their capacity. The optimum charge current is 1/10 of capacity. Pb batteries are not suitable for fast-charging. Follow battery manufacturer instructions.

Charging of Pb Battery

Set the charge current (0.1-10.0A) and nominal voltage. The voltage should match the battery. Press START/ENTER for more than 3 seconds to start charging. The screen displays real-time charging status. Press START/ENTER again to store parameters, or BATT TYPE/STOP to end the program.
