Problems solved by technology

But batteries have their serious disadvantages: short driving range, short service life and high cost, which hinder the popularization of electric vehicles
Temperature differences between battery cells will result in the aging rate of different battery cells, and the result is a shortened life of some battery cells
Since the battery pack is operated by connecting battery cells together, the failure of a single battery cell will cause damage to the entire battery pack

Embodiment Construction

[0056] Regarding the type and specification of the battery core, I choose the laminated battery core. Compared with cylindrical cells, laminated cells have lower internal resistance and thus generate less heat during charging and discharging. And it has a high energy / power density. Due to its flat profile and large exposed surface, it facilitates heat exchange.

[0057] The battery box I designed has 86 large-scale laminated battery cells (100Ah, 3.7V, such as figure 1 ). The cells are connected by novel clips that provide electrical connections where space is limited, as described below.

[0058] Two battery cells are connected face to face in series ( figure 2 ), connect the different electrodes of the two battery cells through a small clip ( image 3 ). This will form a two-cell series connection (dual-cell for short). Two sides of the duplex with cooling channel plate ( Figure 18 ) contact for heat exchange.

[0059] The two cores are placed in the same orienta...

Abstract

The invention provides a clamp system for electrical connection among cell units. The clamp system for electrical connection among cell units has a novel structure, and a cooling fluid can effectively and efficiently cool power cell packs of electric automobiles in a uniform and well-distributed mode. The system comprises a large clamp, a small clamp and an end clamp, wherein the large clamp is used for crossing a cooling deflecting plate and providing electrical connection between two dual cores, the small clamp is used for providing electrical connection between two battery cells inside a dual core, and the end clamp is connected to an anode of a first dual core and a cathode of a last dual core and is used for being connected to a cable of a main power supply.

Description

[0001] This application was submitted on January 21, 2012, the international application number is "PCT / SG2011 / 000029", the Chinese patent application number is "201180003001.6", the invention name is "power battery cooling device", and the applicant is Feng Guoan's invention patent Divisional application of the application. Background technique [0002] introduce [0003] With the gradual depletion of oil resources and the environmental pollution caused by burning gasoline, electric vehicles (EVs) will be the future of transportation. But batteries have serious disadvantages: short driving range, short lifespan and high cost, which hinder the popularization of electric vehicles. [0004] Regulating the temperature of the battery during continuous charging and discharging is a big challenge. [0005] For the vast majority of electric vehicle lithium batteries, the temperature specifications are usually as follows: [0006] Working temperature: -20°C to 60°C [0007] Charg...
