Miljöstabilitetskammare för batteritestning

JOEO är en ledande leverantör av Environmental Stability Chamber med mer än 20 års branscherfarenhet av design och tillverkning av produkter för temperatur- och fuktighetskontroll, och vi erbjuder ett brett utbud av testutrustning för miljötillförlitlighet för testning av batterier av alla storlekar. Vi erbjuder lång erfarenhet av laboratorier som testar NIMH-, blysyra- och litiumjonbatterier, allt från små cellceller till stora batteripaket.

Battery Environmental Stability Chamber are offered to a variety of industries, including the automotive, computer, telecommunications, defense, and alternative energy markets. With the reduction of vehicle emissions and the development of electric hybrid vehicles, the need for lithium-ion battery testing has become more urgent.
Each of our test chambers is built to meet specific test requirements and can be connected to battery circulators, control and monitoring data acquisition systems, and other test equipment to form a complete integrated test solution.

Lösningar för batteritest

The environmental stability chamber can range from a small benchtop chamber for testing small cells to a large walk-in chamber for testing large battery packs, with an operating temperature range of -73 ° C to +190 ° C and an optional humidity range of 10% to 95%. Can range from small benchtop units to large walk-in rooms.
