Electric energy has always been the most convenient energy source during our daily life , and we also store it through various methods to enable us to use this energy anytime and anywhere, such as lithium batteries in mobile phones, rechargeable batteries in electric vehicles, and so on. After years of technological innovation and continuous improvement in comprehensive performance, rechargeable lithium batteries have been applied in many fields. However, due to this, comprehensive testing of batteries is necessary, as various accidents often occur during the charging and discharging process of lithium batteries, leading to personal injury and property losses. Therefore, battery discharge testing is an important part of various battery tests. Battery discharge testing is very helpful for evaluating battery cycle life and discharge performance.

Generally speaking, the performance of a battery is affected by various factors such as battery temperature, battery internal resistance, charge and discharge cycle times, discharge current, and discharge mode. For batteries stored for a period of time, storage time, storage temperature, etc. also affect the performance of the battery during use. Therefore, testing battery discharge testing characteristics is a time-consuming and repetitive task.

Due to the heat generated during the charging and discharging process of the battery, which affects the data accuracy of the battery charging and discharging test system, the MC series EV test temperature control system provided by Beijing WIIP Co. Ltd. provides constant temperature, constant pressure, and constant current circulating fluid to the tested battery modules and battery packs, and simulates different operating conditions of the battery modules and battery packs. When selecting a temperature control system, it should be configured with reference to the minimum temperature of the battery pack or battery module that needs to simulate the working condition, simulating the working condition of - 40 ℃, and selecting Mca series products; Simulate the working condition of - 20 ℃ and select Mct series products; Simulate 5 ℃ working conditions and select Mcc series products. MC series products have multiple options, and flow, pressure, and temperature can be individually controlled; It also has air blowing and leak detection functions. The MC series new energy vehicle battery pack, motor, and controller test temperature control system ensures stable and efficient temperature control and cooling effects within the range of temperature control accuracy, assisting users in the stable use of main equipment.

EV test temperature control system is a professional temperature control system designed based on the requirements of new energy electric vehicle industry for product performance, safety, and environmental adaptability. It can meet environmental simulation, performance simulation, reliability and other professional tests of the motor, controller, battery pack, transmission, hybrid engine, vehicle OBC, DC/DC, CCU, electronic pump, cooling pipeline of new energy electric vehicles need.

At present, the MC series electric vehicle testing and temperature control system has launched seven product series, namely, MCc, MCt, MCa, MCy, MCm, MCs, and MCe, which are subdivided into hundreds of models to meet different market demands and user experiences. Temperature range: - 40~150 ℃, flow range: 0.5~90L/min, pressure range: 0~600kPa; Support circulating fluids such as antifreeze, heat transfer oil, transmission oil, and engine oil; Can switch constant temperature output, internal circulation mode, external circulation mode, and constant power mode; Linear temperature change rate, segmented program temperature control, load leakage detection, and automatic liquid return functions meet the comprehensive needs of users.

After years of experiences, MC series EV test temperature control system has served world-renowned auto test manufacturers, major scientific research institutions, colleges, testing institutions, auto parts manufacturers, and end users have covered many new energy vehicle manufacturers at home and abroad.

EV test temperature control system is suitable for different applications and functions to meet all the needs of industry. It has characteristics of wide temperature range, wide flow range, high control accuracy, strong reliability, high field compatibility, complete user interface, mature and stable software, and high service efficiency.

MCc direct cooling EV test temperature control system adopts the direct heat exchange mode between refrigerant and circulating liquid, with high heat exchange efficiency, fast temperature response and high performance.

MCt pressure EV test temperature control system adopts a closed pressurized coolant circulation design. Through system pressurization, the saturated vapor pressure of the circulating liquid (antifreeze) is increased, so as to realize high temperature operation condition of antifreeze; the closed coolant circulation system can isolates the contact between circulating fluid and air, and can keep the circulating fluid from deteriorating for a long time under high and low temperature conditions. It is a favorable assistant for high and low temperature experiments and airtight experiments in EV testing.

MCa cool storage EV test temperature control system adopts a two-stage low-temperature special compressor to realize ultra-low temperature and high temperature control, each output circuit is independent, which can realize independent temperature control of each circuit.
