This white paper proposes an innovation to battery management systems (BMS) for battery electric vehicles (BEVs) to address current challenges with charging. The key challenges are long charge times, overheating during charging, and only being able to charge batteries to 80% capacity with fast charging. The innovation involves incrementally increasing the voltage over time, such as raising it every second over 30 minutes, to avoid large voltage surges that cause overheating and limited charging. Test results showed batteries could be fully charged to 100% capacity within 30 minutes without overheating or reduced life. Adopting this incremental voltage increase could solve BEV challenges and help popularize electric vehicles.

White paper on Battery Management System for BEV ( Battery Operated Elec . Vehicles)
1. White Paper on BMS ( Battery Management System) of
BEV ( Battery Operated Electric Vehicles)
In further development after my success in modular battery design being accepted
by all MNC & local Indian companies to increase mileage of BEV ,I am floating
this white paper on BMS ( Battery Management System)
This Innovation was done to resolve existing challenges of BMS like
- Longer charge time for BEV resulting in time loss & BEV being not getting popular
- Overheating of battery while charging
- Only 80 % charge possible when charged at higher speed charging at
increased voltage
- Life of battery affected due to fast charging and increased voltage
All above challenges are due to few root cause in fundamental construction and
chemical process happening while electric charge is given to Cathode & Anode ,
be it NiCd, Nickel–Metal hydride, lithium-ion, Li-ion polymer, and, less
commonly, zinc–air and Li-ion- Phosphate or LTO or any other battery
Detailed experiment has resulted in solving all above challenges as mentioned below :
-Any battery mentioned above could be started with given nominal current and
voltage depending upon its chemistry.
-But due to large voltage surge ,it heats up and also loses its charging filed to 80 %
only .So till date fast charging was considered damaging to battery and its life was
short and also taking longer time of voltage was nominal
-This was resolved my experiment done in lab where voltage was increased in
small increment with help of a timer .Every second voltage was increased to
reach peak after 30 Minutes .
-Results were astonishing, as battery did not heat up, was charged to full 100
% capacity and also charged in 30 minutes flat
- This will help fast charging LTO also if done with incremental voltage
increase rather than High voltages ( be it any value of Voltages)
-LTO type of battery already charges at low voltages , so may charge in few
minutes with my method and save time and overheating is avoided and also
increase battery life further .
2. - All other battery types(NiCd, NickelMetal hydride, lithium-ion, Li-ion polymer )
can be done with increasing Voltage with small incremental value and see that
results are amazing .Innovators can try this Innovation of incremental Voltage and
affirm my results to start working on new BMS system with timer to give small
voltage increment for stipulated given of time ( it can be 15,30 ,45 or 60 minute
)depending upon time available for charging your BEV .
Reaching from (X) Voltage to (2 X) in 15 ,30, 45, or 60 minutes
( Time depends upon BMS system and customers requirement to charge BEV)
- This small change in charging pattern by incremental voltage will solve BEV
challenges faced till today .
- I am sure all innovators ,manufacturers and charger BMS system makers will
adopt this new system to cater to market with more full proof method of fast
charging without worrying about overheating , 80 % charging only , longer time to
charge and shorter battery life .
If anybody has more suggestion to this innovation is welcomed ,as my purpose of
this test was to solve all pending challenges with BMS to help market BEV with
more better technology to replace fossil fuel vehicles and make our mother earth
free of pollution .
