I Product Overview
3.3kw high efficiency intelligent charger is designed to charge power batteries of electric vehicles. This series of products adopt the most advanced technologies such as LLC resonant, active power factor correction, microcomputer measurement and control, digital adjusting, fully sealed waterproof technology and so on. Its features include: wide input voltage range adapted to global general voltage; High input power factor that significantly reduces the input current as well as heat generated by input cables, so the charger can be safely used in family; Low harmonic current that reduces interference to other electric equipment. Full range soft switching is realized to achieve high conversion efficiency and slight electromagnetic interference, the charger is more energy-saving and money-saving to use; the charger is designed according to IP66 protection grade and achieved high waterproof performance. Another feature includes small size, light weight, quiet operation, beautiful appearance, simple installation, operation and maintenance and so on.
The charger adopts microcomputer measurement and control technology, embedded CPU can accurately detect various states of battery. Advanced multi-stage charging mode can prevent the battery from be over-charged and over-discharged, minimize overheating and water loss phenomenon caused by over-charge, slow down polar plate vulcanization phenomenon caused by over-discharge, extend the service life of batteries. The charger will stop automatically after fully charged.
The charger has functions of temperature compensation, automatically shut down after fully charged, battery reverse connection protection, output short circuit protection, AC input under-voltage protection, overheating protection and so on, and these functions can ensure safe and reliable use.
II Safety Instructions
Please read these instructions carefully before you use the charger:
(1) For safety consideration, the charger adopts AC single-phase three-wire inputs which contain live, neutral and protective grounding wire. The shell of charger connects protective grounding wire. When using the charger, you should connect it to power grid with a quantified 16A three-hole socket which contains a grounding pole and controlled by a leakage protection air breaker with leakage protection function to prevent leakage and fire.
(2) Please use dedicated 16A plug and socket of reliable quality for the charger (Socket requirements: flame-retardant shell and cables of the socket, thick internal springs that not less than 0.8mm and has a good elasticity), or it may burn the plug and socket, even cause severe fire! Copper core cables thicker than GB 2.5mm2 are suggested to be used as power connections to prevent the cables from becoming too hot when charging ,so to prevent fires.
(3) Please do not disassemble the charger; this may cause electric shock or other injuries.
(4) If the charger need to be connected to AC power supply with extension cables, please make sure that the extension cable can withstand the maximum input current(GB 2.5mm2 copper core cable is recommended to be used), and limit the extension cable length within 10m.
(5) Don’t place the charger in water or rain position; otherwise there is a danger that may cause electric shock and damage to the charger.
(6) The charger’s DC output plug should be connected reliably to the socket, if they are damaged or loose, please replace them immediately, otherwise it will cause overheating in the plug position, and even cause serious fire.
(7) If the charger product any abnormal sound or smell during working, please unplug the power plug immediately and contact the service department. Do not attempt to open the shell of charger, to prevent electric shock.
(8) Make sure that all air vents are unobstructed to prevent charger overheating. Do not place the charger near a heat source; the charger should be left enough space to ensure ventilation and use of connectors.
(9) Please disconnecting the charger's AC input power if you need to move it.
(10) Make sure that AC power supply voltage matches chargers’ input voltage. For inquiries, please contact your supplier or local power Supply Corporation.
(11) Battery voltage and the nominal voltage of the charger must be matched; otherwise it will damage the charger or batteries.
(12) Do not pull, twist or shake the cables to avoid damage to the charger’s cables and connection terminals. If the cable is worn, please replace it immediately.
III Preventing Leakage and Fire
1. Correct use of Breakers, Sockets and Cables
(1) Its required to use a leakage protection air breaker with leakage protection function.
(2) Its required to use reliable qualified 16A three-hole socket to connect the charger to AC power.
(3) Input cables of leakage protection air breaker is required to use copper core cables with flame-retardant jacket, the cables’ core diameter is not less than 2.5mm2.
(4) The cables between leakage protection air breaker and 16A socket are required to use copper core cables with flame-retardant sheath, the cables’ core diameter is not less than 2.5mm2.
(5) Prevent plugs, sockets from dripping or splashing.
Note: According to statistics, 80% fire accident caused by an electric car occurred during charging, main reasons for this are insufficient core diameter size of cables, poor quali
