I Product Overview

CH4100 series 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

-3-

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-

(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 quality plugs

and sockets, poor contact of plugs and sockets, poor flame-retardant sheath or shells of breakers,

plugs and sockets and so on.

2. Correct Use of Input Connections

(1) It’s required to use a dedicated 16A power plug for the charger;

(2) It’s required to use copper core cables with flame-retardant sheath; the cables’ core diameter is

not less than 2.5mm2.

(3) Make sure that the plug is clean (no dirty) and no damage before charging.

3.Charging Environment Requirements

(1) Spacious and airy;

(2) No flammable materials; prohibited charging in warehouse.

(3) Keep away from valuables such as automobiles.

(4) Keep away from bedroom when charging at night.

(5)Prohibit placing the charging plugs, charging cables or charger itself on car cabs, plastics

-5-

chairs and other inflammable objects.

IV Regularly Maintenance

(1) Check 16A sockets regularly, if the connection between the socket and the plug is loose or

poor contacting, they should be firmly connected or replaced before the charger be used. The poor

contact may result in overheating and burning of the plug and socket, and even cause a fire.

(2) Check the leakage protection air breaker regularly using the test button to ensure its protection

function is valid.

(3) Make sure to use a dedicated input cable and plug for the charger.

(4) Make sure that there are no foreign matters between the charger’s shell and the cooling fan to

avoid damage to the fan．

(5) Make sure that the appearance of battery is not ballooning; the battery is not overheating when

charging.
