SMART POWER BACK-UP SOLUTIONS FOR URBAN INDIA
URBANISATION IN INDIA – AT A GLANCE In India, urbanisation was caused after independence, due to adoption of mixed system of economy. In recent century, urbanisation is taking place at a faster rate. Source : en.wikipedia.org/wiki/Urbanisation
URBANISATION IN INDIA – AT A GLANCE As reported in 2011 Census - MUMBAI (12.5 million) 3.1% DELHI (11.1 million) 4.1% KOLKATA (8.9 million) 1.9% Population in all these cities are expected to cross 16 million by the end of 2018 Source : en.wikipedia.org/wiki/Urbanisation
ELECTRIFICATION TO URBAN INDIA In urban areas, the access to electricity is 93.1% In rural areas, the access to electricity is 52.5%
ELECTRIFICATION TO URBAN INDIA In the peak power requirement, there is a huge gap between electrical energy requirement & supply, over national grid. As a consensus decision, demand of urban India is catered on priority. -1.4% 14.5% -22.2% -1.0% -12.9% -2.2%
TYPICAL POWER SITUATION IN URBAN INDIA A study report published by World Economic Forum, in January 2013 reveals, Less than 15 minutes power cut at a stretch (89%) 15 to 30 minutes power cut at a stretch (7%) More than 30 minutes power cut at a stretch (4%) Source : Energy Vision 2013 , January 2013 : World Economic Forum
TYPICAL POWER SITUATION IN URBAN INDIA Study report of World Economic Forum, Jan. 2013 - Sample size : 9963 Data collection period : June – July 2012 Source : Energy Vision 2013 , January 2013 : World Economic Forum
Urban India experiences repeated short power cuts TYPICAL POWER SITUATION IN URBAN INDIA Urban India experiences repeated short power cuts
Repeated short power-cut TYPICAL APPLICATION SCENARIOS Repeated short power-cut High power electrical gadgets for urban application Intelligent power solution, which is capable – To deliver instantaneous high power Minimize energy consumption in float Float application
TYPICAL FAILURE MODES Typical failure of back-up power batteries on float is related to - Corrosion of plates Exposure of plate due to lack of timely topping up
IMPROVEMENT OPPORTUNITIES - BATTERY SMART BATTERY DESIGN Reduction of corrosion rate through plate optimization : Selection of grid alloy Optimum paste density Control of paste morphology.
IMPROVEMENT OPPORTUNITIES - BATTERY Selection of grid alloy Optimum alloy selection significantly increases battery life Battery Type : LUMINOUS 12V150Ah Test Schedule : 100% DOD at 3 hour rate, Discharge load 400 Watt, 3D + 12C
IMPROVEMENT OPPORTUNITIES - BATTERY Selection of optimum paste density Higher paste density ensures higher battery cycle life Battery Type : LUMINOUS 12V150Ah Test Schedule : 100% DOD at 3 hour rate, Discharge load 400 Watt, FD + 8C Density A > Density B End of life
IMPROVEMENT OPPORTUNITIES - BATTERY Control of paste morphology Plate production processes tailored to generate a high level of tetra-basic lead sulphate 4BS improves battery cycle life Battery Type : LUMINOUS 12V150Ah Test Schedule : 100% DOD at 3 hour rate, Discharge load 400 Watt, FD + 8C
IMPROVEMENT OPPORTUNITIES - INVERTER SMART INVERTER DESIGN Increment of discharge load capacity, by optimum design of overload tripping switch Reduction of depth of discharge Optimum selection of high initial current in-rush
IMPROVEMENT OPPORTUNITIES - INVERTER Selection of higher discharge load Selection of a higher discharge load is better for batteries in float/cyclic application Battery Type : LUMINOUS 12V150Ah Test Schedule : 100% DOD at full load + Charge with RAPIDCHARGE 1500VA Inverter
IMPROVEMENT OPPORTUNITIES - INVERTER Controlled depth of discharge Controlled depth of discharge using higher discharge voltage cut-off Battery Type : LUMINOUS 12V150Ah Test Schedule : Discharge @C10 rate with variable DOD + Charge in LCT @15Amp CC with 120% charge return
IMPROVEMENT OPPORTUNITIES - INVERTER Selection of high in-rush current High initial current helps the battery to regain power, fast. Battery Type : LUMINOUS 12V150Ah Test Schedule : Discharge 100% DOD at C3 rate + Charge in LCT with variable current till 14.4V, Hold for 3 hours, Float at 13.8V with charge return 104%
