Future development of cr2032 button battery management
The distribution of the components, costs and weight of the battery system is actually an interesting question. For a rated small battery pack (20kwh), a large battery pack (60kwh), a PHEV battery pack (8-10kwh) and a HEV pack, the cost of the electrical system and the battery management system (BMS) is one set to one pack, so these two items are actually diluted with the ratio of capacity kwh.
Reading SAE's Denso's content on the BMS system of HEV, some of the content about design is quite meaningful, and some content is excerpted for everyone to see.
Simply put, this product is implemented around the cost reduction of lithium battery HEVPack. Take the previous generation of lithium battery BMS and look at it, and further increase the channels of each ASIC.
A brief discussion on the future development direction of cr2032 button battery management
Observing the changes in AFE, the reduction of chips has reduced the cost by 36%. The core is that Denso has semiconductor technology, which has increased the voltage resistance of ASIC to 150V, and the entire power supply has been reduced.
There is an implicit and interesting point here. The self-discharge of small-capacity lithium batteries and the difference in self-discharge caused by AFE leakage and working current differences are not felt when the battery is large, but when the battery is small, the difference in the entire path will cause subsequent changes, at least the passive balancing current is also pulled down. Stack is the difference between power modules. Through the high-voltage merging mode, the difference becomes smaller.
The shell material selection of BMU and BMS is actually the plastic shell and metal shell that need to consider waterproofing (especially for liquid cooling systems), working and balanced heating, and EMC (ESD issues in module and Pack assembly).
I personally think that in the future, the BMS system needs to integrate multiple capabilities together and solve and optimize from the chip perspective. Especially driven by HEV, in fact, the cost of a single BMS and BDU has been reduced to a very low level (problem of proportion). The amount of EVs used, because the cost of electronic and electrical systems is relatively low, actually pays attention to the price of battery cells. In the future, if it is really done on a large scale, the money will not be saved by a penny, but at least it will be deducted by a dollar.
Summary:
Companies that make 48V and HEV will definitely pose very strict challenges to the cost refinement of BMS, BDU, and even DCDC electronic and electrical systems. Here, money is made by the block, which is actually the norm in the car. If we look at the components that have been booming in new energy vehicles in recent years, it is actually not normal. Money cannot be wasted, it must be earned little by little. Brothers who make BMS must adapt to this change in price trend in advance. The price of BOM will be more brutal than we think.
