5kW self-cooled on board battery charger

CHR series high frequency charging power supply are charging for 24V~750V Lithium batteries and Lead-acid batteries, their single power range from 1KW to15KW, the highest single current can be 100A and reach hundreds kW after parallel operation. They could be widely used in circulation charging of Electric car, Electric taxi, Electric bus, Electric forklift, Golf car, Electric bikes, Electric cruise and so on with the advantages including light weight, small volume, stability, efficiency and safety. They can Auto Switch between Float Charging and Equalized Charging with the protect function including battery polarity reverse and DC output short circuit and over load.As an on-board charger, with its own characteristic like waterproof, dustproof, shockproof, and the Electrical performance all meet safety standard. Its uses the micro-computer controlled to control the charge and then auto finish battery charge without manual operation. With its main specialty of more charging zone in accordance with charge and discharge characteristic, it can rapidly full the battery charge while protect the battery charge in a high level in order to avoid the damage by improper charge. Another advantage of this charger is that it could auto identify different seasons and preset the highest charge voltage. This charger has two charge mode: Balance charging mode and Pulse charging mode; you can set charging ways by the buttons of the charger and its Default state is balance charging mode.

IV. Features

1.high power density: this series charger using advanced switching technical, small loss and with high efficiency. It consist of PFC power correction circuit and DC/DC converter. It achieves the widely output 100~240VDC. The power factor get 0.99, and efficiency reach 95%.

2.self-air cooling. This series charger using selft cooling type. Advanced PCB design, strict select the components, it leads our productsradiationso small and decrease the volume, it make the stability much higher.

3.Advanced charging mode. This charger using 5 stage charging curve. Max voltage is pre-setting. And automatically identify winter and summer mode. Auto and repairing mode as option.

4.Perfect protection function: over heated protection: when the temperature over 75°C, the output decrease to 50%, when the temperature over 85°C, the charger will be shut down. When the temperature get down in normal range, the charger get recovery.

Short circuit protection: when charger happen in short circuit condition, the charger will be shut down, after out of faulty condition, charger will be restart. Reverse connection protection: when the battery are wrongly connect to the charger, the charger will not working and will not break. Low-voltage protection: when AC voltage &gt;85V, <170V, the charger will working on 50% output condition, when AC voltage power &lt;85V or> 265V, the charger will be shut down. When the voltage recover the normal range, the charger will start working. Charger working too long protection: when the charger working time beyond 12 hours, the charger will be shut down.
