Whereas current incidents of electrical automobile fires have alerted us on battery security wants, a Jaipur based mostly startup, Pure Battery Tech, is constructing batteries that it claims can maintain harsh temperatures as much as 200°C and nonetheless present optimum effectivity.
With the rise in demand for bigger battery packs with extra security options, Puneet Jain, CEO, Pure Battery Tech, says they’re now designing lithium-ion batteries that may work past their rated capability and in addition maintain harsh temperatures.
“The lithium cells (NMCs) might get heated and contact as much as 55-60 levels Celsius, resulting in thermal runaway. The same old batteries out there out there might use a thermal foam or epoxy sheet that may shield as much as 100 or 125 levels Celsius. By utilizing specialised thermal pads and warmth safety gadgets, we’re in a position to safe the whole pack as much as 200 diploma Celsius. These supplies may also take up automobile shocks to safeguard battery inner elements,” he explains.
For guaranteeing security from defective cells, the agency has launched fused connection know-how, which isolates the defective cell within the pack from the remaining. “A battery pack is a mixture of cells. If you’re utilizing a easy connection kind and if any cell goes unhealthy, it can’t isolate itself from the common pack. Whereas larger companies like Tesla go for costly applied sciences like ultrasonic bonding to deal with such points, now we have provide you with a less expensive resolution of utilizing fused connections for our battery packs,” says Jain.
Jain calls the optimisation function as their distinctive promoting level. “If a consumer orders a 50Ah (ampere-hour) battery, we give them a 51.5Ah battery. It is a refined distinction, nevertheless it seems to be a fantastic trust-building issue,” he says.
To optimise house and match extra battery capability in restricted automobile house, the agency makes use of customised ABS constructions to maintain the lithium cells in place. The ABS construction has concerned cautious choice of supplies that may allow the battery to be compressed additional and permit packing extra capability. A typical battery of 50Ah capability is housed in a field of 400mm thickness and with the compression construction, it’s lowered to 365~370mm. The house saving (approx. 30mm all-round) can be utilized for growing the capability of the battery additional.
Whereas the staff had earlier confronted difficulties in deciding on supplies that might present each thermal and shock safety, and in addition in designing ABS constructions, discovering a producer in India was an even bigger problem. “We couldn’t discover a producer in India and therefore we moved to importing from international locations like China and Germany. That is additionally a motive that places our price a little bit greater in comparison with our rivals,” Jain says.
The enterprise was began in 2019 with the leasing of electrical rickshaw batteries. It was later shifted to a few different monetary fashions, realising the preliminary heavy investments. “I partnered with electrical automobile producers and generally we even did the supply service by hiring drivers. All these choices weren’t very scalable with the restricted funds. Now we at present focus solely on constructing batteries,” he provides.
He strongly believes that permitting a free hand to experiment is a good way to innovate. “I’ve fairly some examples in our manufacturing unit the place we had skilled our manpower from little technical experience to adapt efficiently in innovating at our manufacturing unit flooring. These with not so greater schooling backgrounds have experimented loads with testing, repairing, tinkering, and are actually understanding methods of manufacturing environment friendly outcomes,” Jain says.
Jain expects to quickly introduce an efficient liquid cooling mechanism. His staff is designing the pump and pipe programs for liquid cooling to successfully hold the bigger packs cool. Jain goals to develop a fantastic battery ecosystem deploying battery swapping and charging infrastructure in India in the long term. He says, “We’re already in talks with some traders. We need to create an infrastructure the place the batteries could be simply serviced, recharged and all managed by way of cell apps.”
The agency is at present planning growth and searching for refined OEMs to co-design battery packs customised for his or her autos. It is usually in strategy of hiring battery researchers, mechanical engineers, provide chain managers, product growth specialists, and electrical engineers.
