environmental test chambers Battery Explosion Proof High & Low Temperature Chamber Double Layer High & Low Temperature Chamber Walk in Battery Explosion Proof High & Low Temperature Chamber International standard Energy Conservation Remote network system Circuit System Why does battery heat,fire and explosion? What will happen under such phenomenon? Burn somebody directly or decrease the insulation Burn somebody directly, Harm somebody flammable liquid ignition. with battery fire. What test should be battery made? Secondary battery environmental test Lithium-ion batter advantages: Battery type primary cell just Solar cell Physical battery thermal battery fuel cell Its action voltage is 3 times to nickel cadmium battery and nickel metal hydride battery, the machine just nedd equipped with a few batteries, small size and portablity. secondary cell can be charged primary cell chemical battery Small size portabilityenergy density, with same capacity, its weight is only half of the nickel cadmium battery and nickel metal hydride batteries, its volume just 20 to 50% of them. more time secondary cell Continuous charge can be charged and discharged under any condition and stock reservoir which will not reduce energy capacity to continuous charging. nickel-cadmuum battery Small size NI-MH battery secondary battery lithium-ion battery Safety and environmental protection Lead storage battery Over-charging ability and over-thermal safety. No cadmium, lead, mercury, etc. Environmental test necessity and test method The necessary reason for environmental test Necessary test Secondary battery applied preservation test charge or discharge under different Under specific environment under specific environment to environmental temperature to check charge/discharge battery secondarybattery performance under test battery leakeage and repeatedly and check every such temperature condition safety performance battery performance Temperature requirement： Temperature requirement： Temperature requirement： Vibration requirement： With econdary battery widely used, the environment will also be changed as mobile phones, computers, household appliances, electric tools, automobile such area change Low/High Temp. Performance Test range of battery type and usage) range of battery type and range of battery type and Charge/discharge test Transport test Simulate air transport, road transport (UN) specification chemical reation affected maintain 6s on peak value environmental test chambers Temperature control range Temperature fluctuation Cooling rate Heating rate Temperature uniformity Humidity control range Humidity fluctuation Adopts 1.2mm thickness stainess steel(SUS304) External material Adopts 1.2mm thickness Cold rolled steel sheet / powder spraying Heat insulating material 100mm thickness polyurethane plate ＋10mm thickness mineral wool Centrifugal blower Semi-closed Germany Bock, Germany Bitzer Air cooling, water cooling Fin - and - Tube Heat Exchanger Nickel chromium alloy heating wire Steam humidifier Standard configuration 2∅ 100MM pressure relief port, 4 explosion-prood chains Multipoint temperature monitor Adopts Sanwood developed controller, which can be used to acquire surface temperature points of multiple products Automatic fire extinguishing and automatic shutdown of the machine to protect the equipment from burning When the battery will produce gas, it will detect gas solubility and discharge to outdoor when it exceeds the standard Exhaust valve Internal material Material / components Humidity uniformity When the test sample produces harmful gas, ventilate and exhaust internally Interior size(mm) W*H*D Outer size(mm) W*H*D Operating ambient temperature Power supply E-mail: [email protected] www.sanwood.com
