The Research &Development team of Ampere Vehicles has developed India’s first, indigenous lithium-ion battery charger. President of India Ram Nath Kovind has unveiled the product recently at the National Capital. Dr Harsh Vardhan, Indian Minister of Science and Technology was also present during the event, amidst nearly 1000 scientists, technocrats, academicians, students and industry persons.
The lithium-Ion charger project is supported by Technology Development Board, Ministry of S & T, India, as part of the Make-in-India initiative.
“Our commitment and resolve to sustainable mobility are manifested in the consistently superior products that we have launched over the time. Our new lithium-ion charger is an extension of this commitment. I am sure this will be a milestone in optimising the vehicles and battery life for consumers and achieve economies of scale for EV companies,” said Hemalatha Annamalai, Founder & CEO, Ampere Vehicles.
The advanced lithium-ion chargers are designed with two-stage charging profile in which charging voltage and the current’s levels can be amended based on the requirements of battery manufacturers’ recommendations. The microcontroller based control and monitoring systems provide active battery reverse polarity protection, over temperature cut off and output short circuit protection.
Its battery capacity rating is 48V, 20Ah/24Ah with the onetime full charging time of 4-5 hours. Weighing 1.65 kgs, the input voltage range of the charger is 185 Vac to 265 Vac and has the operating temperature zero degrees to fifty-degree centigrade. Also, the charger is enabled with the input and output overvoltage protection.
During the event, Ampere’s two lithium-ion powered scooters-V48 and Reo- were flagged off. These vehicles will have lesser weight due to lithium batteries (almost 50% reduction), so the payload of the battery will be optimized letting the vehicles to run up to 65-70 km per charge, which just takes 3- 4 hours to get fully charged.
