In a leg-up to its technological innovations, Chennai-based two-wheeler major TVS Motor Co has been granted a patent for an invention relating to a device that would avoid battery drain in motor vehicles. The Chennai patent office has granted the patent after being satisfied with the submissions put forward by the company regarding the efficacy of the invention. TVS Motor claimed the invention provides a device for avoiding battery drain in a motor vehicle which comprises a magneto connected to a regulator-rectifier. The device enables the battery to supply power to the direct current (DC) load directly and to receive power from the regulator-rectifier for charging of the battery through the diode. Also, the battery is selectively disabled from supplying power to the brake lamp through the diode. This reduces battery drain leading to various difficult situations, notably, those associated with the electric start of the engine, according to a patent document filed by the company.
Generally, in a motor vehicle, the DC loads such as turn signal lamp, brake lamp, beeper, horn and service indicator lamps, among others, are connected to the battery. When the engine is off, these DC loads are driven by the battery causing drain of the battery. This leads to electric start problem since it is driven by battery.
Especially, a brake lamp, which is one of the DC loads, is turned on when the brake is actuated. As a safety requirement, the driver is required to apply the brake while starting a vehicle with electric starting mechanism. The company said the invention is aimed at addressing drawbacks and avoiding, or at least minimising, the battery drain. Besides, it leads to cost saving and is capable of being readily incorporated in the vehicle.
TVS Motor continued to grow ahead of the industry for the third year in succession, registering sales of 28.58 lakhs two-wheelers in 2016-17, growing 11% over the previous year. It had registered a sales growth of 16% in August 2017 over the year-ago period. Total revenue, including other income, increased to Rs 13,363 crore in FY17 from Rs 12,195 crore in the previous fiscal.
Despite lower sales from November 2016 to March 2017 due to demonetisation and impact of discount to the dealers to sell BS III stocks, the net profit increased to Rs 558 crore from Rs 489 crore. The company has a strategic partnership with BMW Motorrad to develop and manufacture sub-500 cc bikes both for domestic and global markets.
The BMW G310R is the first motorcycle to be manufactured under this partnership. Manufacturing and exports of this motorcycle has commenced. TVS Motor will launch their own motorcycle based on this common platform during the current fiscal.
