New energy vehicle assembled battery temperature control apparatus

Abstract

The invention discloses a new energy vehicle assembled battery temperature control apparatus. An adjusting system comprises an operation panel, a BMS controller, a first Bluetooth adapter and a temperature display module, wherein output ends of the operation panel and a battery temperature sensor are respectively electrically connected with the input end of the BMS controller, the output end of the BMS controller is electrically connected with the input ends of the first Bluetooth adapter and temperature display module, the output end of the temperature display module is electrically connected with the input end of the operation panel, the output end of the first Bluetooth adapter is electrically connected with a heat exchanging system, and the heat exchanging system comprises a second Bluetooth adapter, a PLC temperature controller, a refrigerating apparatus, a heating apparatus, a circulating water pump and heat exchanging liquid. By adopting the new energy vehicle assembled battery temperature control apparatus, the temperature of an assembled battery is kept in a set interval, so that the performance of an assembled power supply is maximally utilized, the service life of the battery is prolonged, more convenience in operation is realized by virtue of the Bluetooth connection with the system, and the maintenance is facilitated.

Description

technical field [0001] The invention relates to the technical field of new energy vehicle batteries, in particular to a temperature control device for combined batteries of new energy vehicles. Background technique [0002] At present, with the rapid development of the new energy industry, batteries are used in a wider range of fields, such as in automobiles. By using power battery systems to provide electric energy for electric vehicles, the use of non-renewable resources can be reduced. [0003] However, the battery will generate a certain amount of heat whether it is in the charging state or the discharging state. When the heat is too high, the temperature of the battery will exceed the normal temperature range value, which will reduce the performance of the battery and reduce the cycle life. In addition, when the battery When in a low-temperature environment, the performance of the battery will also decline. Most of the existing devices for cooling the battery use circui...

Problems solved by technology

[0003] However, the battery will generate a certain amount of heat whether it is in the charging state or the discharging state. When the heat is too high, the temperature of the battery will exceed the normal temperature range value, which will reduce the performance of the battery and reduce the cycle life. In addition, when the battery When in a low-temperature environment, the performance of the battery will also decline. Most of the existing devices for cooling the battery use circuit control, and the circuit is easily damaged during long-term use. Especially in some high-temperature areas, the problem of heat dissipation of the circuit cannot be solved, and The wiring is located inside the car body, and maintenance work is very troublesome
