1500W battery charger

Specifications

I Product Summary & Application Scopes

The charger is applicable for various Lead-acid batteries like Flooded, GEL, AGM, hemicolloid etc.,hemicolloid hemicolloid  It features light weight, small volume, stable performance, high efficiency and reliable security etc., It can be switched automatically between the floating and balancing charging and also has the protection functions of reverse connection, output short-circuit and overload and so on.

The charger is widely used for battery-charging cycles in electric vehicles such as electric forklift, golf cars, electric trucks, electric tour bus, electric yacht, cleaning machines, or Uninterruptible Power Supply (UPS), solar energy, wind power dynamo and electric communication system on the railway etc.

1. Thermal Self-Protection: When the internal temperature of the charger exceeds 75℃, the charging current will reduce automatically. If it exceeds 85℃, the charger will shutdown protectively. When the internal temperature drops, it will resume charging automatically. 

2. Short-circuit Protection: When the charger encounters unexpected short-circuit, it will automatically stop to output. When fault removes, the charger will re-start in 10 seconds.

3. Reverse Connection Protection: When the battery is polarity reversed, the charger will cut off the connection between the internal circuit and the battery, and refuses to start. It can avoid any destroy.

4. Input Low-voltage & Over-voltage Protection: When the  AC input Voltage is lower than 85V or higher than 265V, the charger will shutdown protectively and automatically resume working with the voltage is normal again.

IV Main Accessories & Wiring Diagram

Thermal Sensor TC-615 together with LED TC-618 (as per the specific vehicle model) or a single Thermal Sensor TC-615.

Thermal sensor TC-615 provides the real-time detection of the battery’s temperature in the charging process to prevent charge-off or charge due.

LED TC-618 shows the state of the charging such as ＜80% or ＞80% or 100% and can be fitted onto the vehicle panels.

Wiring Diagram:

Note: Thermal sensor and LED share the connector SP1310/P which pairs up with the charger’s communication port (SP1312/S, near the charger’s output terminal). Plug in the connectors before charging. Place the LED at the conveniently location. A thermal sensor should be fixed on the battery shell. Recommend to place it in middle position  between two cells. Make sure the DC cord is connected to the battery properly. .

Please check carefully the labels on the casing of the charger before using in order to  completing the transaction check the label on the charger before using, it can provide some help for you to understand the performance and the specification of the charger.

i. Bar Code Label:

Attaches on the output terminal of the charger. For example, SN10071001

1007: Production batch number.

HD VER 1.6 : Version number from the manufacturer

ii. Model Label: take the model TCCH-48-25 for example

a) “Input 100~240VAC 50/60Hz 14/8.1A”: The rated input current is 14A at 115VAC and 8.1A at 220VAC;

b) “48V   25A@240VAC 48V   24.5A@115VAC”: The maximum output current is 25A at input 220VAC, and 24.5A at input 115VAC.

It is the important symbol to evaluate whether the charger works normally.

The LED will flash red several times when AC is first connected, then the LED will flash green once. The number of red flashes denotes the present curve. e.g. If the red flashes three times, it means the present curve is curve 3, and so on.

Ten charging curves respectively represents different capacities of the Lead-acid battery. I4 means the equalizing current. Algorithms_105 means the procedure code from the manufacturer. e.g. the charger of Lead-acid flooded battery 48V for example,

48V Flooded Battery-1.5KW Charger (Algorithms_105)

1. The LED will flash red several times when AC power is connected, and then the LED will flash green once. The number of red flashes denotes the present curve. E.g. If the red flashes three times, it means the present curve is curve 3.

2. To choose another curve, please cut off the power supply first, then uncover the label, pressing the button while connecting the power. If you want to choose curve 3, release the button after the 3rd LED Flash. Now the selected curve (e.g. curve 3) will be recorded in memory. If you want the charger to work with the selected curve (e.g. curve 3), cut off the power and reconnect it.

3. The charging curves which represent the charging modes for 10 different capacities for Lead-acid battery are customized at the factory before delivery according to customer demand. Please note the corresponding Lead-acid battery type must be the same.

 VIII   Common Faults & Solutions

In case of the charging fails, please examine all the outside lines carefully to make sure that they are connected correctly. Apart from the circuits failure, please check the failure code of charging LED and handle it according to the following table.

2. “_” denotes one second pause

3. Above LED flashing sequence is one cycle; the LED will flash repeatedly if the fault has not been removed.

▲ Wrong Battery: Verify the battery voltage range matching with charger or inspect the battery for damage.

▲ Overcharged: Confirm the battery capacity and the selected curve are matched or if the battery is defective.

▲ Battery Overheated: Check the temperature at the external thermal sensor. If overheated, the charger will start the battery protection.

▲ Incorrect AC Input Voltage: Check that the AC input voltage is in accordance with the requirement.

▲ External Thermal Sensor Fault: Ensure connect the thermal sensor correctly.

▲ Communication Interface Fault: Make sure the communication have been correctly connected or if it is damaged.

▲ Charger Overheated: Check if the ambient temperature is too high or the ventilation is smooth.
