New types of cars powered by electricity or hydrogen are constantly developing and gaining increasing recognition, posing new challenges for car manufacturers. An important factor in the success of electric vehicles is the availability of spare parts suppliers and service providers who utilize their expertise to provide targeted support to established car manufacturers.Bertrandt AGcompany Provide customers with a testing platform with an environmental chamber for testing high-voltage batteries under different climate and load conditions, covering module level, hybrid battery, and pure electric vehicle battery. The battery will be exposed to various extreme conditions during climate simulation or accelerated aging during durability testing.40 For many years,BertrandtWe have been providing successful research and development services for specific industries, and our business covers a wide range 57 A region with approximately13,000An employee is an operating company. This year, the company isEhningenEstablished a large high-voltage battery testing center in Germany. asLAUDALoyal fans,BertrandtPut fromLAUDAThe temperature control technology obtained is equipped in a brand new testing chamber.

as low as -40 °CHigh precision temperature control

The company has specifically ordered adjustable volumetric flow ratesLAUDAProcess cooling equipment to meet the high requirements of customers in the automotive industry. The equipment is used to control the temperature of the samples in the environmental chamber, such as high-voltage energy storage devices, which are high-voltage batteries used in electric vehicles and solar energy equipment. During this period, the customer used two large machinesSUK 400WThe equipment is undergoing performance testing, with an additional ten unitsSUK 350WType equipment is used for fatigue testing and simulated operation. Meanwhile, process cooling equipment can be used in -40 to 120 °CAccurate temperature control within the specified range.

LAUDAThe uniqueness lies in the use of water-Ethylene glycol mixture as temperature control medium and refrigeration equipment equipped with single-stage refrigeration circuit. In terms of compliance with European fluorinated gas regulations, due to the abandonment of cascade refrigeration equipment, the high requirements for the second stage are not includedGWPValue refrigerant,LAUDACan ensure the safety of future designs. To ensure that -40 °CThe refrigeration equipment must also have sufficient power reserve, as it can be precisely adjusted even at extreme temperatures. Due to water-Once the temperature of the ethylene glycol mixture reaches -45 °CLeft and right (depending on concentration) will start to freeze, so it is necessary to accurately coordinate each individual process cooling equipment.

Fully automatic filling simplifies the testing process

In order to simplify the testing process for customers in the automotive industry,LAUDAThe process cooling equipment is equipped with fully automatic sample filling and emptying functions. This technology has always belonged toLAUDAThe service scope is currently being demanded by an increasing number of customers and has developed into an industry standard.LAUDAHeating and Cooling System Project ManagerManuel FaulhaberAs a service provider,BertrandtServing customers from various industries, the system has been additionally designed with the function of fully automatic filling and emptying of the entire equipment. Thanks to this,BertrandtTesting procedures can be completed using different temperature control media for each customer, eliminating the need for tedious manual filling and emptying - saving service providers a lot of time.
