Electrovaya Launches Maya-300 Low-Speed Electric Vehicle; Using ExxonMobil Separator in Batteries
23 January 2008
|Electrovaya’s Maya-300 will be a zero-emission passenger car with a range of up to 120 miles per charge.|
Electrovaya is launching the Maya-300, a zero-emission, low-speed, all-electric vehicle. It will have an extended range of up to 120 miles on a single charge, powered by Electrovaya’s Lithium-Ion SuperPolymer battery technology with integrated iBMS (intelligent battery management system).
The Maya-300 will use Electrovaya’s lithiated manganese oxide MN-Series batteries with a balanced energy and power density optimization. (Earlier post.) The MN-Series is Electrovaya’s preferred chemistry for transportation because it offers up to 40-60% higher energy density with comparable safety characteristics to its Phosphate-Series offerings.
The Maya-300’s battery system incorporates battery separator films from ExxonMobil. (Earlier post.) The advanced performance separators exhibit enhanced permeability, higher meltdown temperature and melt integrity without compromising the shutdown temperature and mechanical strength. The higher meltdown temperature significantly increases the film’s thermal safety margin.
Electrovaya recently introduced its upgraded version-3 iBMS for transportation applications. The iBMS has been designed for 15V and 48V modules which may be integrated to form intelligent Battery Systems from 48V to 710V.
The iBMS is an integrated, CAN-bus solution with fail-safe capabilities. It optimizes the battery system for optimal performance at a cell and module-level, protects the system and provides system-level interface communications to optimize the battery system together with other elements such as motor, controller and charger.
The iBMS consists of both distributed and system control intelligence integrated in the battery system design.
Top speed of the Maya-300 is electronically regulated to either 25 or 35 mph, as per state regulations. The on-board battery charger allows for convenient recharging with standard 110V outlets.
This announcement complements several other Electrovaya clean transportation applications, including the Maya 100 EV (earlier post) and conversions of Ford Escape Hybrids to plug-in hybrids (earlier post).
